摘要
研究了直流落点不同无功补偿方式对交流电力系统静态电压稳定的影响。当直流落点采用固定电容器补偿时,可将该节点看作PQ节点;而采用大容量同步调相机补偿时,该节点可看作PV节点。基于计及负荷静态电压特性的交直流电力系统连续潮流方法,分析了直流落点分别为PQ节点和PV节点下,直流落点近区交流系统的静态电压稳定性,得出直流落点采用大容量同步调相机进行无功补偿有助于提高近区交流系统的静态电压稳定性。
The way of reactive power compensation on the static voltage stability of AC system at the neighborhood of DC location is studied in this paper. It is pointed out that the node can be regarded as a PQ type if the capacitor is used as reactive power compensation equipment at the DC location, while the node can be regarded as PV type if the synchronous compensator is used as reactive power compensation equipment. The static voltage stability of AC system is studied with PQ or PV node of DC location by continuation power flow method, which considering the static voltage characteristics of load. It is concluded that it will improve the static voltage stability of the AC system if the synchronous compensator is used as reactive power compensation equipment at DC location.
