Opis:
The paper presents a comparison analysis of the noise generated by wind turbines and the one generated by a ventilation shaft of a working coal mine. The aim of the research was to compare the frequency and amplitude distribution of those sources, especially in the infra range. The ultimate aim it is evaluate possible environmental impact on human annoyance or severity. During the research noise signals were recorded utilizing low frequency microphones, shielded by windscreens. Microphones were localized at the heights of 0.0 m, 1.5 m (approximate location of a human ear in a standing position) and 4 m. Additionally, a measurement position of a microphone in relation to the ground surface was observed. Measurements at ground level were performed according to the standard PN-EN 61400-11:2013-07 and in vertical position, where the microphone was mounted "upside down" with the grid flush with the board. The possible influence of wind speed was also monitored. The results of the measurements are discussed.

Opis:
The article presents a design of a floating platform for offshore wind turbines. The concept is a modification of the Spar design and consists of three variable section columns connected to each other by a ballast tank in the lower part of the platform. This solution makes it possible to influence the position of the centre of buoyancy and the centre of mass of the structure. Compared to the classic Spar platform structure, the centre of buoyancy can be higher than mid-draft, which will provide the platform with greater stability. At the same time, this concept is better, in terms of technology, because of its modular structure and smaller bending radii.On the basis of the model testing performed, the hydrodynamic coefficients of the designed platform and its response to a given regular wave were determined (the transfer functions for heave and pitch motion were determined). Then, based on the damping coefficients, the platform was modelled in the ANSYS AQWA program and the results were very similar.

Opis:
A digital twin is a digital replica, a mathematical model of a given object, product, process, system, or service. A digital twin enables the attainment of a significant amount of data and it can be used to gain comprehensive knowledge about a given object, its behaviors, and reactions. The constant ability to monitor the product and its reactions contribute to its improvement and the exclusion of errors, as well as its optimization, which in turn allows for a more perfect product. This article presents a model of a digital twin for the analysis of the operation of a slewing bearing in the structure of a wind turbine. The quality of the bearing is directly related to the quality of the materials from which they were made, the process of thermo-chemical treatment, and the accuracy of all its elements, as well as its proper assembly. The bearings are characterized by very narrow tolerances. Errors in the shape of cylindricity cause distortion of the bearing raceway, stress accumulation, and jamming of rolling parts. This leads to rapid bearing wear as a result. The condition for the approval of bearings for sale is the successful passing of all tests, both geometric and strength. This is to develop quality standards that bearing suppliers must meet. The article presents an analysis of the load distribution that prevail in rotor blade bearings at the limit loads of a wind turbine. The basic types of the most commonly used coronary bearings for wind turbine applications were considered. A methodology for constructing computational models of slewing bearings, using the finite element method, was developed. An original way of simulating rolling parts with rod elements – for rollers and superelements – for the support balls was proposed. A numerical FEM model of a slewing bearing with a wind turbine rotor hub is presented. The calculations accounted for the susceptibility of the bearing rings and hub, as well as the stiffness of the mounting screws. Areas of bearing raceways, where rolling parts achieve the greatest loads, have been identified. Demonstrated by diagrams are the deformations of the rotor hub seats and bearing rings.

Opis:
The paper presents an innovative solution which is heave plates with holes. The long-known heave plates are designed to damp the heave motion of platforms. They are most often used for Spar platforms. The growing interest in this type of platform as supporting structures for offshore wind turbines makes it necessary to look for new solutions. Based on the available literature and the authors’ own research, it was concluded that the main element responsible for the damping of heave plates is not so much the surface of the plate, but its edge. Therefore, it was decided to investigate the effect of the holes in heave plates on their damping coefficient. Model tests and CFD calculations were performed for three different structures: a smooth cylinder, a cylinder with heave plates with a diameter of 1.4 times the diameter of the cylinder, and a cylinder with the same plate, in which 24 holes were cut (Fig. 1). Free Decay Tests (FDT) were used to determine the damping coefficient and the natural period of heave, and then the values obtained were compared. The full and punched heave-plate designs were also tested with regular waves of different periods to obtain amplitude characteristics. The results obtained are not unequivocal, as a complex motion appears here; however, it is possible to clearly define the area in which the damping of a plate with holes is greater than that of a full plate.

This paper is based on designing a modified rotor for a drivetrain in a Type-III wind turbine system for maximum power generation to work effectively under low and high wind speed and its variation. In this paper three drive trains are designed for the gearbox to provide regulated torque and thrust force. For time to time variation in wind speed the voltage sag and during over speed condition voltage swell problem can be solved by using this modified design. The pitch control, gear box and yaw of the wind turbine basically focused for modification. Mainly the gear box for the rotor causes sluggish motion of the rotor during low wind speed. This paper explained the design of modified rotor control for the gear box in DFIG based (Type-III) wind turbine. Also in this paper how the modified rotor system can be helpful for reactive power control highlighted with comparison with existing models. For designing MATLAB Simulink platform is taken and validated using CFD mechanical design analysis. Using these types of modified drive trains maximum power for the wind turbines is enhanced by 40–60% of its reference value.

Opis:
Wind energy is one of the most relevant renewable energy. A proper wind turbine maintenance management is required to ensure continuous operation and optimized maintenance costs. Larger wind turbines are being installed and they require new monitoring systems to ensure optimization, reliability and availability. Advanced analytics are employed to analyze the data and reduce false alarms, avoiding unplanned downtimes and increasing costs. Supervisory control and data acquisition system determines the condition of the wind turbine providing large dataset with different signals and alarms. This paper presents a new approach combining statistical analysis and advanced algorithm for signal processing, fault detection and diagnosis. Principal component analysis and artificial neural networks are employed to evaluate the signals and detect the alarm activation pattern. The dataset has been reduced by 93% and the performance of the neural network is incremented by 1000% in comparison with the performance of original dataset without filtering process.

Opis:
The following paper covers a method for wind turbine selection with a horizontal axis of rotation basing on real in-field measurements of wind conditions. The basic meteorological properties and characteristics obtained during measurement campaigns using necessary equipment as well as the used methodology are vital for successful investment in wind farm. The main goal of in-field investigation is to collect meteorological data using a measurement mast installed at the possible future wind farm location. The conducted measurement campaign provided wind directions, velocities and wind blast parameters. The measurements were conducted in the northern Poland using measuring system installed on 100 meter high mast. The system was equipped with all devices necessary to measure and record the basic wind parameters. The reliability of measurements was verified using statistical data for the Weitbull distribution and the wind rose. In this way, the energy potential of raw air stream that could possibly drive a wind turbine was determined. Among 6 pre-selected wind turbine types, the optimal one for a given location was proposed.

Opis:
Some Renewable Energy Sources (RES), such as wind power, are often regarded as intermittent. That means they are not available on demand, but rather depend on external conditions e.g. such as the weather. In order to manage these resources, it is advised to combine them with energy storage or other energy sectors, what is known as “sector coupling”. This approach is set to mitigate the negative impact of unstable renewable energy sources and manage the generated surpluses. In this study, a system combining wind turbines, district heating network and short-term thermal energy storage was proposed and examined for the instance of the Westfjords, Iceland. Ísafjörður, Patreksfjörður, Bolungarvík and Flateyri are the exemplary communities with existing district heating networks, chosen to investigate the implementation of the system. A short review of the current state of the energy sector in Iceland was provided to present the local conditions. Wind potential in the described area was estimated as high in comparison with average wind turbine generation in the European Union and a few instances of wind turbines placement were analyzed in this study. For locations close to the district heating net-work, a long-term correlation between power generation and usage was proven. However, locating wind turbines in places with better wind conditions, provides stable output and a similar amount of energy produced by fewer generators.

Opis:
The continuous development of the technologies used in the construction of wind turbines makes them a promising and widely used source of energy. Wind turbines keep getting bigger, resulting in increases in their production capacity. However, both the wind turbines and their support structures are exposed to huge loads that cause the deformation of the rotor blades, vertical deflection, or vibration of the support structure and rotor blades. In this context, the issue of monitoring the technical condition of the structures of such facilities becomes important, particularly in terms of reliability and the service life of the whole system. This document shows a method of measuring a wind power station using the Leica P40 terrestrial laser scanner. The object of the research was a few-years-old wind turbine located in the village of Kluczewsko (near Włoszczowa). The examined wind turbine is 35 m high measured to the turbine base and has rotor blades that are almost 13 m long. The measurements were performed at two stages: during turbine operation and with the wind turbine at rest. This enabled us to determine the changes in the geometry of the object at dynamic loads during the operation of the plant. Each series of measurements was made from three stations evenly arranged around the entire facility, which allowed for a full recording of the wind turbine geometry as well as of its supporting structure. The measurements taken at rest and during operation of the turbine were recorded on the basis of the same points of reference, which allowed us to obtain data on the same coordinate system. The measurements were used to determine the deflection of the turbine support from the vertical axis at rest and the change of deflection under wind pressure during the turbine’s operation. The vibration amplitude of the turbine’s support during operation was also determined. In addition, an attempt was made to determine any changes in the geometry of the rotor blades under wind pressure. The obtained results are presented in a tabular and graphical manner.
Ciągły rozwój technologii stosowanych w budowie turbin wiatrowych sprawia, że jest to coraz bardziej obiecujące i powszechniej występujące źródło energii. Budowane są coraz większe elektrownie wiatrowe umożliwiające zwiększenie zdolności produkcyjnych. Jednakże zarówno turbiny wiatrowe, jak i ich konstrukcje nośne narażone są na wysokie obciążenia powodujące odkształcenia łopatek wirnika, wychylenia od pionu czy też drgania konstrukcji nośnej. Pojawia się więc zagadnienie monitoringu stanu technicznego konstrukcji tego typu obiektów, szczególnie istotne w aspekcie niezawodności i czasu żywotności całego systemu. W niniejszym artykule przedstawiono sposób pomiaru elektrowni wiatrowej przy użyciu naziemnego skanera laserowego Leica P40. Obiektem badawczym była kilkuletnia elektrownia wiatrowa, znajdująca się w miejscowości Kluczewsko niedaleko Włoszczowy. Badana elektrownia wiatrowa jest obiektem o wysokości 35 m mierzonej od podstawy turbiny i długości łopat wirnika wynoszącej prawie 13 m. Pomiary wykonano przy dwóch stanach elektrowni: w trakcie pracy turbiny i w stanie spoczynku, co umożliwiło określenie zmian geometrii obiektu przy obciążeniu dynamicznym w trakcie pracy elektrowni. Każda z serii pomiarowych została wykonana z trzech stanowisk rozmieszczonych równomiernie wokół całego obiektu, co pozwoliło na pełną rejestrację geometrii turbiny wiatrowej, jak również konstrukcji jej podpory. Pomiary turbiny w stanie spoczynku i w trakcie jej pracy zostały przeprowadzone z wykorzystaniem tych samych punktów nawiązania, co pozwoliło uzyskać dane w jednolitym układzie współrzędnych. Na podstawie wykonanych pomiarów określono wychylenie od pionu podpory turbiny w stanie spoczynku oraz zmianę tego wychylenia pod naporem wiatru podczas pracujący turbiny. Wyznaczono również amplitudę drgań podpory w czasie pracy turbiny oraz przeprowadzono próbę określenia zmian geometrii łopat turbiny pod naporem wiatru. Uzyskane wyniki zostały przedstawione w sposób tabelaryczny i graficzny.

Wind energy is one of the most environmentally friendly energy industries. Wind power is used in more than 70 countries of the world to produce electricity. Wind power plants generate more than 1% of the world’s electricity. Wind energy is considered to be one of the most popular renewable energy sources. In countries where this energy is already widely used, the environmental conditions substantially improve. To increase the efficiency of wind power plants and work reliability, and also to solve other problems, it is necessary to carry out climate research on wind energy and collect information on the distribution of wind energy depending on wind speed profiles, etc.

Opis:
The use of condition monitoring techniques in wind energy has been recently growing and the average unavailability time of an operating wind turbine in an industrial wind farm is estimated to be less than the 3%. The most powerful approach for gearbox condition monitoring is vibration analysis, but it should be noticed as well that the collected data are complex to analyse and interpret and that the measurement equipment is costly. For these reasons, several wind turbine subcomponents are monitored through temperature sensors. It is therefore valuable developing analysis techniques for this kind of data, with the aim of detecting incoming faults as early as possible. On these grounds, the present work is devoted to a test case study of wind turbine generator slip ring damage detection. A principal component regression is adopted, targeting the temperature collected at the slip ring. Using also the data collected at the nearby wind turbines in the farm, it is possible to identify the incoming fault approximately one day before it occurs.

Opis:
This paper deals with problems relating to the impact of wind power plants on the landscape and their acceptance by society. The advantages and disadvantages of wind power energy produced by such energy plants are discussed. It is observed that most of the disadvantages of classic windmills can be avoided with the application of wind turbines with vertical spin axes. These turbines are designed for consumers who need power sources up to 1.5 kW. This paper also presents new and original construction solutions for these types of turbine masts, which are defined as types “F,” “2F” and “F/2F”. It is concluded that the presented solutions are easily integrated with the landscape, architecture and infrastructure of the region. The work also introduces research results concerning wind speed in the Białystok region (Nowosiółki, near Krypno). As the range of wind speed changes over time is relatively wide, this influences the value of momentary turbine power. The research results indicate that from October to March, wind speeds are significantly greater than during the remaining months.

Opis:
Annoyance ratings for artificially created noises, resembling the main characteristics of temporal wind turbine noise, were studied by means of a listening experiment involving 21 participants with normal hearing. Three types of stimuli were examined: broadband noise (−4 dB/octave), noise generated by moving cars, and narrowband noise. All stimuli had the sound level fluctuations typical for wind turbine noise. The magnitude of the sound level fluctuations was measured in a quantitative way, by using the characteristics of amplitude modulated sound: modulation rate and modulation depth. Our aim was to examine how the modulation rate and the modulation depth influence the noise annoyance assessment of broadband and narrowband amplitude modulated noises. Three different modulation rates, 1, 2 and 4 Hz, and sound level fluctuations (a measure of the modulation depth), 3, 6, 9 dB, were applied to each type of stimuli (with exception of noise generated by the moving cars) and investigated. The participants in the listening experiment were presented with sound stimuli in laboratory conditions and asked to rate their annoyance on a numerical scale. The results have shown a significant difference between the investigated conditions. The effect was particularly strong between the annoyance judgments of different types of noise (narrow and broadband), and modulated versus unmodulated noises. Temporal fluctuations occurring in wind turbine noise are very pertinent to the perception of annoyance and could be responsible for its being a relatively annoying noise source. The obtained results were discussed and compared to the typical modulation rates and level changes that occur in recordings of real wind turbine noise.

A review of the literature gives several guidelines for the design of a Permanent Magnet Synchronous Generator (PMSG) for Small Wind Turbines (SWT) applications. This paper presents Finite Element Analysis (FEA) of a Surface Mounted PMSG. Several optimization tests are run in order to yield the lowest Total Harmonic Distortion (THD) and cogging torque with the highest induced voltage. The results of the optimization tests are then utilized to design an initial “optimized” circumferential Internal PMSG. This optimized design is then compared to a non-optimized design, as well as the results of the Surface Mounted PMSG.

The general review of applications and functionalities of the SCADA system was carried out. An application that performs the assumed visualisation, control, alarm, protection and archiving functions was proposed. Designs were made in the Vijeo Citect environment. As the application is of universal nature and is based on components which exist in the design environment, it can constitute a model and a template which will serve the purpose of creation of visualisation of any process of energy generation from the RES sources.
