Opis:
This paper shows application of the method of sum of power losses to determining energy losses which occur in hydraulic rotary motor in situation when not all laboratory data are at one’s disposal or when no use is made of data contained in catalogue charts. The method makes it possible to determine the coefficients, ki, of energy losses occurring in the motor. The method of sum of power losses is based on the approach proposed by Z. Paszota, in the papers [3 ÷ 9]. It consists in adding power flow of energy losses occurring in the motor to power flow output and comparing the sum to the power flow input. Application of the method is exemplified by using a A6VM hydraulic motor.

Opis:
In this paper are compared two models of energy losses: that suggested by Prof. Paszota, Z. in monograph “Energy losses in the hydraulic displacement motors – definitions and relations serving the evaluation of the efficiency of hydrostatic drive” [18] and that of Prof. Balawender, A. in “Energy analysis and methodology of testing of low-speed hydraulic motors” [1]. By using the data obtained from the tests of SWSB-63 hydraulic motors [2] the graphs which illustrate mechanical, volumetric and pressure losses in function of the parameters on which the losses directly depend [18 ], have been elaborated and showed in comparison with the description of such losses in function of the parameters assumed in [1]. The below presented text has been complemented in relation to that published in the monograph [4] and read during the scientific technical conference „Cylinder 2010” organized by the Mining Engineering Centre „Komag”, Gliwice, and held on 20÷22 September 2010 in Rytro, Poland.

Opis:
Full picture of the energy losses in a hydrostatic drive system is a picture of the power of energy losses in the system elements. Paper presents the areas of the power fields of energy losses occurring in the elements of some hydraulic systems with different structures of the hydraulic motor speed control. Proposed graphical interpretation allows analysing and comparing different hydrostatic drive systems. In many constructed and manufactured machines currently used hydrostatic drive systems or electro hydrostatic systems of varying complexity. Today, the need for energy-efficient systems forces to some extent the development and improvement of computational methods using computer aided relating to energy efficiency systems. Hydrostatic systems especially in modern machines play a very important role. Actuators, such as hydraulic motors, hydraulic cylinders is commonly used for a long time, including on machines and equipment land and marine. Unawareness of proportions of the energy, volumetric, pressure and mechanical losses in elements is often the case. Problems connected with energy efficiency are essential for improvement of functionality and quality of hydrostatic drive systems, characterised by unquestioned advantages. Energy efficiency of hydrostatic transmissions, particularly those with throttling control of the motor speed, and also efficiency of the hydraulic servomechanism systems may be in fact higher than the values most often quoted in publications on the subject.

Opis:
The aim of the article is to look at the possibility of accurately determining the energy efficiency of drive systems. The results of experimentally determined efficiencies and the efficiencies determined from simulations of two hydrostatic systems with throttling control and fed by a constant capacity pump were compared. The research apparatus was very precisely designed, made and automated. The measuring instruments that were used are characterized by their high measuring accuracy. The issues related to the determination of the energy losses and the energy efficiency of the hydraulic motor or drive system, which should be determined as dependent on the physical quantities independent of these losses, were also discussed. A Paszota diagram of the power increase in the direction opposite to the direction of the power flow, replacing the Sankey diagram of the power decrease in the direction of the power flow in the hydraulic motor or in the drive system, was analyzed. The results showed that a Paszota diagram opens up a new perspective on research on the power of energy losses and energy efficiency of hydraulic motors and drive systems.

Opis:
With increased interest in renewable energy sources, such as photovoltaic farms, a number of studies whose aim was the analysis of their positive and negative impact on the power system was carried out. From the point of view of the system operator, the suitable place of installation and the size of such plant in the network can have a positive impact on the value and direction of power flow, voltage levels, the value of the power loss, short- circuit currents and power factor. However, the biggest difficulty in the application of the farm is its unexpected production characteristic which depends mainly on the weather conditions changing randomly during the day. The most desirable case is a period when this farm is capable of being installed in depth of the network to reduce daily peak demand for electricity. The energy from big, centralized plants working in the system must be delivered to the customers at this time, which generates additional costs of starting units, working in short period of time and increases power losses on lines, which must send higher energy values. Accordingly, the sense of use of an external energy storage systems cooperating with photovoltaic installations is clear. For the grid operator, in the case of large PV farm desirable to be able to use the extra energy of the battery power and the ability to use the farm to reduce the afternoon and evening peaks. This may positively affect production costs and transmit additional energy to the system.

In the paper are presented the diagrams of the structural energy efficiency of system with the throttling control assembly and total energy efficiency of the system with constant or variable capacity pump cooperating an overflow valve with the throttling control of the linear hydraulic motor. Diagrams of total energy efficiency of three hydraulic systems working at the same parameters of speed and load of hydraulic linear motor, which were different due to structure and ability of energy saving were presented and compared. This publication also presents analyses and compares the areas of the power fields of energy losses occurring in the elements of three compared hydraulic systems with different structures of the hydraulic linear motor speed control on example on Load Sensing system. The graphical interpretation of the power of losses in the hydrostatic drive and control system elements lets to compare the same power fields of energy losses with other power fields of another structure. This enables to understand what energy losses are the biggest and in which elements of compared hydraulic systems. The best possibility to use in system, as a supply source of the hydraulic cylinder speed series throttling control assembly, is a set consisting of a variable capacity pump cooperating with a Load Sensing (LS) regulator, which totally eliminates the structural volumetric losses in a system. Power ΔPstv of structural volumetric losses is equal to zero, because the current pump capacity QP is adjusted, by the LS regulator, to the current flow intensity QM set by the throttling assembly.

Opis:
A control system with a proportional directional throttling control valve or a directional control servo valve, controlling a cylinder (linear hydraulic motor) is used in the ship steering gear drive, in the controllable pitch propeller control, in the variable capacity pump control system for hydraulic deck equipment motors or fixed pitch propellers in small ships (for example ferries). The hydraulic system is designed first of all taking into consideration the nominal parameters of the cylinder load and speed. For such parameters, the energy efficiency of the elements and complete system is described. Meanwhile the exploitation conditions can vary in full range changes of the cylinder load and speed coefficients. The article presents a comparison of the energy behaviour of two widespread structures of hydrostatic systems: a standard individual systems with a throttling steering fed by a constant capacity pump. Both hydraulic solutions are described and equations of the total efficiency η of the system are presented. Diagrams of energy efficiency of two hydraulic systems working at the same parameters of a speed and a load of hydraulic linear motor, which were different due to structure are presented and compared, as well ability of energy saving. This publication also presents analyses and compares the areas of the power fields of energy losses occurring in the elements of two hydraulic systems with different structures of the hydraulic linear motor speed control.

Opis:
The article presents the energy performance of a heat pump. The coefficient of performance was taken into account, which is the ratio of the heating energy obtained to the supplied electrical energy necessary for the compressor operation. The focus was on the issue of operating costs of using heat pumps. These costs are mainly influenced by two factors. Firstly, energy performance and the purchase price of electricity. The second factor is investment costs. Heat gains from solar energy were characterized. The value of the solar radiation transmission coefficient for the double glazing was assumed (TR = 0.7). Solar gains were shown in January for windows on the eastern and western facades. The analysis covered the seasonal heat demand for heating. The studies and calculations took into account the occurring heat losses and heat gains from the sun and internal sources with their utilization rate. Particular attention was paid to the fact that the peak power of heating appliances can be calculated by knowing the value of the annual energy demand for heating a building that takes into account the most severe external conditions prevailing in a given climate zone, i.e. the minimum outside temperature.

W artykule omówiono wybrane wyniki badań wykonanych dla operatora sieci przesyłowej nad konstrukcją nowych, niskostratnych przewodów przewidzianych do stosowania w napowietrznych liniach elektroenergetycznych 400 kV. W szczególności omówiono wyniki porównania parametrów elektrycznych wybranych konstrukcji pojedynczych przewodów z przewodami referencyjnymi. Porównano również straty mocy i energii w liniach elektroenergetycznych z wiązkami wykonanymi z przewodów niskostratnych i obecnie stosowanych. Zastosowanie w liniach przesyłowych nowych, niskostratnych przewodów pozwoli na redukcję strat, w porównaniu ze stratami w liniach z przewodami referencyjnymi nawet o 30%.
The article presents selected results of studies carried out for the transmission network operator on the construction of new, low-loss conductors intended for use in overhead power lines. Developed and treated multi-criteria analysis of new types of conductors steel-aluminium (ACSR), homogeneous alloy matrix aluminium (AAAC) Alloy-aluminium (ACAR) and using conductive cores made of copper based alloys, intended for use in bundles of 3-wire on existing towers and bundles of 3- and 4-wire on the new towers. We examined 80 projects of wires. The article discusses the impact of construction on the conductor resistance for alternating current and energy loss. We also compared the energy losses in power transmission lines equipped with bundles made of low-loss conductors with losses in the lines equipped with the currently applied wires. The use of the transmission lines with new low-loss conductors allows the reduction of energy losses in transmission lines by up to 30%, compared to the reference conductors (currently used).

Opis:
A control system with a proportional directional throttling control valve or a directional control servo valve, controlling a cylinder (linear hydraulic motor) is used in the ship steering gear drive, in the controllable pitch propeller control, in the variable capacity pump control system for hydraulic deck equipment motors or fixed pitch propellers in small ships (for example ferries). Energy savings in a constant capacity pump operation can be achieved by means of overflow valve controlled by the oil outlet pressure between the directional throttling control valve and the cylinder. Although structural volumetric losses cannot be eliminated in such a system, but it is possible to reduce considerably structural pressure losses, mechanical losses and volumetric losses in the pump, and mechanical losses in the cylinder too. The paper discusses these energy savings using an earlier developed by Paszota mathematical model of losses in elements, the energy efficiency of the system and the operating range of the cylinder. The paper also presents a comparison of the energy behavior of two widespread structures of hydrostatic systems: a standard individual systems with a throttling steering fed by a constant capacity pump. Both system solutions are described and equations of the total efficiency η of the system are presented. Diagrams of energy efficiency of two hydraulic systems working at the same parameters of a speed and a load of hydraulic linear motor, which were different due to structure and ability of energy saving, were presented and compared.
