The article presents a method for selecting the parameters of the current-voltage characteristics of adjustable reactive power compensation devices used at sectioning stations of railway sections electrified by alternating current with a voltage of 27.5 kV. This technique is based on the experience of operating two types of devices in the traction power supply system. Power control of these devices is implemented by the voltage level at the switching point. Selection of the setpoint voltage and slope characteristics was done. The developed method allows increasing the efficiency of devices by eliminating the voltage losses on the active component of traction loads. That will reduce the loss of electricity in the system of traction power supply. Changing the parameters of the characteristics will increase the relationship between the reactive power consumed in the zone and the voltage measured by the devices. Following the results of the formation of the methodology, an example of the choice of characteristics for a real compensation device is presented.

The objective of this work is to research on a SVC auto-compensation method to improve the power factor of the power supply system. Firstly, the principles of the reactive power compensation of FC+TCR are analyzed qualitatively. According to the deficiencies of this compensator, a novel SVC auto-compensating method based on the variable reactor is presented. The reactor controlled by anti-parallel thyristors is namely as the variable reactor in this method. The secondary-side equivalent inductance of the variable reactor is varied by adjusting the SCR firing angles. And then, the equivalent inductance of the variable reactor of the compensator branch is adjusted indirectly for compensating the corresponding reactive power after the working conditions of the load are changed. Therefore, the auto-compensating of this var compensator is realized. The auto-compensating principles of this compensator have been analyzed, and a research on the compensating parameters of this compensator is given emphatically in this paper. Finally, the essential operation steps of this SVC compensation method are given. The research of this paper has laid a theoretical foundation for this compensator in industrial applications.

Optimization of a power supply system is one of the main directions in power engineering research. The reactive power compensation reduces active power losses in transmission lines. In general, researches devoted to allocation and control of the compensation units consider this issue as a static optimization problem. However, it is dynamic and stochastic optimization problem that requires a real-time solution. To solve the dynamic optimization NP-hard problem, it is advisable to use Swarm Intelligence. This research deals with the problem of the compensation units power control as a dynamic optimization problem, considering the possible stochastic failures of the compensation units. The Particle Swarm Optimization and the Bees Algorithm were applied to solve it to compare the effectiveness of these algorithms in the dynamic optimization of a power supply system.

In a rural power grid 220kV transformer substation in Liaoning Province, because of the appearance of a lot of new impact loads in the power supply area, the original reactive power repertory can not meet the existing load need. As a result, the output 66kV voltage fluctuation affects the power supply security of the users. After a comprehensive evaluation, it is planned to set up a set of ±100M SVG to increase the reactive power repertory to stabilize the system voltage. The electrical system of 220kV transformer substation is huge and often meets with sudden failure; and the capacity of this set of SVG is large, so it may worsen the situation in case of improper control. This paper discusses several operational modes that SVG should have and designs a scheme that can be flexibly switched in several operational modes, which is specifically executed by an overall coordination module. This method has passed the preliminary field operation verification.

The expediency of using a power active filter in the mode of reactive power compensation of the supply network for the powerful sounding pulses shaper power supply system of the Institute of ionosphere NAS and MES of Ukraine is shown. An analysis of the literature has been carried out, which shows the effectiveness of solving the problem of reactive power compensation, filtering higher harmonics of the power supply network using active filtering of higher harmonics of current or voltage using an additional energy source to obtain a compensating signal in the form of current or voltage. The choice of the power circuit for constructing a power active filter has been made. A voltage inverter on IGBT transistors is used as a power active filter. The basic principles of operation of the power active filter control system are described, which are based on the p-q theory of power and provide for the calculation of instantaneous values ​​of the task currents for each phase of a three-phase power supply system. The work of the Matlab-model of the power supply system of the shaper is shown, the oscillograms of the main energy characteristics of the shaper are given. As a result of using a power active filter, the current of the supply network becomes close to sinusoidal, and the power factor tends to 1. A positive effect on the efficiency of the shaper when the power active filter is included in the supply network is noted, which is due to the efficiency of compensation of the reactive power consumed by the shaper from the supply network. The simulation results are presented, in particular, graphs of reactive power change at the point of connecting the power active filter to the supply network, at different levels of reactive power consumption by the shaper. The results obtained confirmed the possibility of using a power active filter in the mode of reactive power compensation of the supply network when solving the problems of improving the electromagnetic compatibility of powerful sounding pulses shapers with the supply network, reducing losses and increasing the reliability of the shapers.
