摘要:

摘要:介绍了发电厂的厂用电系统现状,从厂用电电源来自电网和厂用电电源来自电厂两个方面分析了发电厂厂用电系统加装无功功率补偿设备的必要性。以600MW300MW机组厂用电为例,定性分析了无功功率补偿在发电厂厂用电系统的应用价值,指出厂用电无功功率补偿可提高厂用电运行电压的安全裕度,减少线路和变压器损耗,降低设备负载率,提高线路和变压器输电能力,延缓设备老化。

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.
