Abstract

The aim of this paper is to develop a new way to control active power rectifier (APR) for Reactive Power Compensation (RPC) in a power network. The emphasis of this research was on the theoretical analysis of controllability of the active, reactive and full power in the APR system - power network. On the basis of received results, we can make a conclusion about reactive power regulation with help of APR: it is possible with the use of a new automated control system (ACS). The most important thing is to use this new ACS, when the installations with a non-linear load work in parallel near with the consumption point of current. It allows to decrease the value of input reactive power from the electrical substation and to improve the technical-and-economic indexes of the electrical power supply system in whole for a factory.
