Features of Reactive Power Compensation in Electrical Networks of Coal Open Pit Mines

摘要

This paper discuss the features of reactive power compensation in electrical networks of coal open-cast minings. The authors calculated the value of the reactive power consumed by the network elements. It is established that synchronous motors are able to compensate about 40% of the total reactive power consumption in coal open-cast minings. The paper gives recommendations on the possibility of using synchronous motors as compensating devices in electrical networks of coal open-cast mining. The conducted researches showed that for compensating the reactive power consumed by other consumers, it is more appropriate to use additional compensating devices installed in the places of reactive power consumption.
