Opis:
Electric arc furnace has a variable power consumption with time that causes mechanical oscillations in the adjacent small scale synchronous generators, and consequently, decreases its life. In this paper, we first provide a model for electric arc furnace and is validated using actual measured data. In this paper a real distribution system consisting of the small scale synchronous generator, which feeds industrial loads, including electric arc furnaces, is analyzed and evaluated based on the simulation of the time domain. Using analytical studies and simulation results, the appropriate value for controller parameters of the prime mover is determined in such a way that the mechanical oscillations of the small scale synchronous generator created by the electric arc furnace are reduced. In addition, the response of the transient mode of the small scale synchronous generator is also considered in the proper setting of the parameters. Finally reliability and effectiveness of the proposed parameters are evaluated using real measurement data.

Opis:
In response to the inability of the flexible DC transmission system connected to the AC grid under conventional control strategies to provide inertia to the system as well as to participate in frequency regulation, a virtual synchronous generator (VSG) control strategy is proposed for a voltage source converter (VSC)-based multi-terminal high-voltage direct current (VSC-MTDC) interconnection system. First, the virtual controller module is designed by coupling AC frequency and active power through virtual inertia control, so that the VSC-MTDC system can provide inertia response for AC grid frequency. Second, by introducing the power margin of the converter station into the droop coefficient, the unbalanced power on the DC side is reasonably allocated to reduce the overshoot of the DC voltage in the regulation process. Finally, the power regulation capability of the normal AC system is used to provide power support to the fault end system, reducing frequency deviations and enabling inter-regional resource complementation. The simulation model of the three-terminal flexible DC grid is built in PSCAD/EMTDC, and the effectiveness of the proposed control strategy is verified by comparing the conventional control strategy and the additional frequency control strategy.

Opis:
The problem of large speed loss exists in the traditional passing through the electric phase-separation method of trains, which is more prominent when trains pass through an electric phase-separation zone in the uphill section of long ramps and may lead to the trains not passing through the phase-separation zone safely. In order to solve this problem, based on the energy storage type railroad power conditioner, a train uninterrupted phase-separation passing system based on the energy storage type railroad power conditioner is proposed. The energy storage railroad power conditioner can realize the recovery and utilization of regenerative braking energy of the electrified railroad. In the structure of the energy storage railroad power conditioner, the single-phase inverter is led from the middle DC side of the energy storage railroad power conditioner and connected to the neutral line through the LCL filter and the step-up transformer, which constitutes an uninterrupted phase separation passing system. The single-phase inverter is controlled using virtual synchronous generator technology, which allows the single-phase inverter to have external characteristics similar to those of a synchronous generator, providing support for the voltage and frequency in the neutral zone. The power required by the train to pass the electric phase-separation is provided by the power supply arm or the energy storage system, which not only improves the utilization rate of regenerative braking energy but also realizes the uninterrupted phase separation passing of the train through the control of the voltage in the neutral region.

Opis:
Different from the synchronization mechanism of synchronous generators, the non-synchronous generators must be synchronized with the grid through a controller. Generally, the virtual synchronous generator (VSG) control strategy is adopted for this purpose. In view of the current situation, where the control loops are not comprehensively considered in the research of the synchronization stability of the VSG, this paper considers multiple control loops, such as active frequency loops, virtual governors, power filters and current constraint control, to establish the mathematical model of the VSG and infinite system. On this basis, the correlation formula between power angle difference and control parameters is deduced. Adopting the phase plane method, the influence of different control loops and their parameters on the transient synchronization stability is analyzed. Finally, a setting principle of the frequency modulation coefficient of virtual governors is proposed, which not only meets the response speed of control systems, but also has good control performance.

Opis:
Large synchronous generators are of high importance for the stability of power systems. They generate the frequency of the system and stabilize it in case of severe grid faults like trips of large in-feeders or loads. In distributed energy systems, in-feed via inverters will replace this generation in large parts. Modern inverters are capable of supporting grid frequency during severe faults by different means on the one hand. On the other hand, higher Rates of Change of Frequency (RoCoF) after incidents need to be accustomed by future systems. To be able to analyse the RoCoF withstand capability of synchronous or induction generators, suitable models need to be developed. Especially the control and excitation system model need enhancements compared to models proposed in standards like IEEE Std 421.5. This paper elaborates on the necessary modelling depth and validates the approach with example results.

Opis:
This paper proposes a system design and control technique for a newly developed brushless and permanent magnetless synchronous generator-based variable-speed wind energy generation system, transferring power to a constant voltage dc grid via a three-level Vienna rectifier (VR). The recently established generator named Brushless Induction excited Synchronous Generator (BINSYG) is a wound field synchronous generator (WFSG), whose excitation is developed by controlling an Induction Machine fitted to the same machine structure and sharing the same magnetic core. A new controller is proposed that ensures the stable operation of BINSYG for a wide variation of shaft speeds. VR achieves sinusoidal input current and can control the power factor at its input, which is particularly suitable for wind energy applications. The top and bottom capacitor voltages of the VR are balanced using redundant switching combinations. The system with its proposed control algorithm is modelled in MATLAB/Simulink for a 5 kW rated BINSYG feeding power to a 750 V dc grid. The steady-state and dynamic state simulation results are presented and the controller performance is verified for a wide range of wind speeds. Further, real-time results using the OPAL-RT testbed are presented for the same system to verify the effectiveness of the overall control strategy.

Opis:
Wielobiegunowa prądnica synchroniczna ma liczbę par biegunów p = pPM + pEM. Bieguny (2pPM) są wzbudzane magnesami trwałymi, a na biegunach (2pEl) jest umieszczone uzwojenie wzbudzenia. W artykule przedstawiono prądnicę synchroniczną o liczbie par biegunów p = 6, przy czym cztery pary biegunów są wzbudzane magnesami trwałymi przyklejonymi na powierzchni nabiegunników, a dwie pary biegunów są wzbudzane elektromagnetycznie. W ten sposób straty mocy wzbudzenia zmniejszają się o 66%. Sześciofazowe uzwojenie twornika (2 x 3 fazy) umożliwia zwiększenie mocy znamionowej prądnicy o 3,4% i o taką samą wartość zmniejszają się straty mocy w uzwojeniu twornika. Prądnica przy pracy samotnej i zmianach mocy obciążenia ma możliwość stabilizacji napięcia, a przy pracy na sieć elektroenergetyczną umożliwia regulację, w sposób ciągły, mocy biernej. Uzwojenie wzbudzenia ma małą masę miedzi, tym samym straty mocy w uzwojeniu wzbudzenia są małe.
A multi-pole synchronous generator has a number of pole pairs p = pPM + pEM. The poles (2pPM) are excited with permanent magnets, and the field winding is located at the poles (2pEl). The article presents a synchronous generator with the number of pole pairs p = 6, where four pole pairs are excited with permanent magnets glued on the surface of the pole pieces, and two pole pairs are electromagnetically excited. In this way, the excitation power loss is reduced by 66%. The six-phase armature winding (2 x 3 phase) allows the generator’s rated power to increase by 3,4% and the power loss in the armature winding is reduced by the same amount. The generator in the case of off-gird work and changes of load power has the ability to stabilize the voltage, and when working on-grid it allows continuous regulation of reactive power. The excitation winding has a small copper mass, thus the power losses in the field winding are low.

Opis:
Among the various methods for generating electricity on a ship, a shaft generator system is characterized by the highest energy and economic efficiency. The use of a Permanent Magnet Synchronous Generator (PMSG) in these systems, in comparison to classic synchronous generators, improves the ship’s propulsion efficiency and the system’s reliability. The problem of adjusting the PMSG’s excitation and changing the speed of the generator’s shaft can be solved by the use of modern power and electronic systems. This article presents a method for controlling the mechatronic system of a shaft generator with a PMSG, which enables stable operation to be achieved when changing the rotational speed of the shaft. Analytical and simulation studies were carried out and have enabled the boundaries of the area in which the PMSG can operate to be determined, while maintaining the required electrical power. The results have shown that the use of a PMSG instead of an EESG can increase the energy efficiency of the shaft generator system and increases the system’s reliability

In the presented system a generator and a battery of supercapacitors were connected with use of power electronic converters. The synchronous generator is connected to the DC network via an AC-DC converter and the super capacitor is connected with means of an isolated DC-DC converter. Both converters have been equipped with auctioneering diodes to prevent the flow of equalizing currents. The theoretical basis and results of experimental research obtained on a laboratory test-stand equipped with the aforementioned system are presented.

Elektrownia wytwarza więcej energii elektrycznej, jeśli turbina wiatrowa i sprzęgnięty z nią generator synchroniczny pracują z prędkością obrotową dostosowaną do prędkości wiatru według kryterium maksymalnej mocy. Napięcie prądnicy powinno być możliwie duże zarówno przy małej prędkości obrotowej, jak i przy prędkości znamionowej. Uzyskuje się to poprzez podzielenie uzwojenia twornika prądnicy na sekcje i łączenie sekcji uzwojenia, w czasie pracy prądnicy, szeregowe bądź równoległe. W artykule przedstawiono prądnicę wzbudzaną magnesami trwałymi z uzwojeniem twornika podzielonym na dwie sekcje i trzy sekcje. Sekcje uzwojenia są łączone wyłącznikami elektromechanicznymi. Sterownik mikroprocesorowy mierzy parametry pracy prądnicy: napięcie, prąd, częstotliwość, oraz steruje załączaniem i wyłączaniem wyłączników.
The power plant generates more electricity if the wind turbine and the synchronous generator associated with it operate at a speed adapted to the wind speed according to the maximum power criterion. The generator voltage should be as high as possible at both low speed and rated speed. This is achieved by dividing the generator armature winding into sections and connecting the winding sections, during generator operation, in series or in parallel. The article presents a permanent magnet generator with armature winding divided into two sections and three sections. Winding sections are connected by electromechanical switches. The microprocessor controller measures the generator’s operating parameters: voltage, current, frequency and controls the switching on and off of circuit breakers.

The models and their implementation in the microcontroller of an industrial inverter (with the local control) are discussed, including the usability of the implementation with large-scale developments constraints in mind. The comparison is conducted based on existing standards (for synchronous machines and diesel generators) in order to determine their needed evolution, to define the requirements for future grid-friendly inverter-based generators, notably implementing a VSG solution.

Opis:
The process of synchronization of synchronous generators and power electronic converters with the power grid may take on quite different forms. This is due to their specific principles of operation and essential differences in energy conversion process. However, since synchronous generators and power converter often operate in the same utility network, coherent rules should be defined for them. There-fore, this paper aims at a formulation of the uniform and consistent interpretation of synchronization with the power grid for both types of aforementioned units. The author starts from the classic interpretation of synchronization for synchronous generators and power electronic converters, considered as micro-generators, specifies their mathematical and numerical models and then performs simulation tests. Selected synchronization algorithms are described in detail. Simulation tests are used for analysis of the elaboration of outcomes. The results of simulation tests are handled to formulate a uniform interpretation of synchronization for the micro-generation systems considered. Based on the results obtained, appropriate parallels are built between the two systems being compared. It is shown that the synchronization processes are identical regardless of the micro-generation unit considered. Nonetheless, they differ significantly due to their properties in transient states. Inverter systems have higher dynamics but their disadvantage lies in the relatively high sensitivity to disturbances and the complex selection process of the synchronization algorithm.

The paper presents the background and results of numerical simulation and experimental research of a system using auctioneering diodes used to distribute the power of direct current between two power converters operating in parallel. Non-isolated power distribution systems using blocking diodes are used in the ship's electrical power systems, however, they create problems related to control and the possibility of ground faults. Another issue occurring during the operation of this type of systems is the increased heat dissipation. Selected problems related to the operation of the above systems have been identified by means of simulation studies and experiments carried out in a 11 kVA laboratory system and the theoretical basis along with results are provided in the article.
