基于区域电压距离的无功补偿投入的研究

在无功补偿位置、容量确定的情况下,对电力系统无功补偿的投入进行了研究。首先利用"电气距离"进行分区,运用电压稳定裕度思想,考虑主导节点法的不足,提出了基于区域电压距离指标的无功补偿投入参数模型;然后采用粒子群算法对该模型下系统的这种无功补偿最优投入参数进行了计算,并给出了具体的计算流程。IEEE-30算例结果表明,所提参数有效地改善了系统无功投入的合理性,并相应降低了系统损耗,对系统无功补偿有较好的实用价值。

Reactive Power Compensation Based on Regional Voltage Distance

Putting the reactive power compensation into power system when the position and capacity of reactive power compensation is determined is studied.The "electrical distance" is used to divide the grid firstly and a parameter model based on regional voltage distance is put forward by using voltage stability margin theory.Then,the optimal input of reactive power compensation in this model is calculated by particle swarm optimization(PSO).The results of IEEE-30 numerical example show that the proposed parameters are practicable because they can make reactive power compensation much more rational and reduce the system losses,which provides a better practical value for reactive power compensation in power system.
