Application of reactive power compensation for auxiliary power system of a power plant

Abstract

Abstract:

Abstract:This paper introduced the current condition of auxiliary power system of power plant, and analyzed the need to add reactive power compensator for auxiliary power system from the aspect of two sources of the auxiliarypower:one is from the grid and the other is from power plant.Took auxiliary power systems of 600MW and 300MW units as examples,this paper performed a qualitative analysis of the application value of reactive power compensation for auxiliary power system,and pointed out that the reactive power compensation could improve the safety margin of auxiliary power operating voltage,decrease the losses of lines and transformers,reduce the equipment load factor,improve the transmission capacities of lines and transformers,and delay the ageing of equipment.
