摘要
基于 GPS的同步相量测量单元 ( PMU )能够测量节点的电压相量。本文从节点电压初值选择、多平衡节点潮流计算、潮流方程直接可解等三个方面初步分析了应用PMU后电力系统的潮流计算问题 ,并讨论了这三种方法的应用条件和特点。算例表明 。
GPS based synchronous Phasor Measurement Units(PMU)which have been successfully developed and equipped in power systems in recent years can provide bus voltage phasor measurements.The applications of PMU with high precision in power flow calculation are analyzed in the paper in the following ways.1)take the PMU measurements with low precision as initial values in the iteration of power flow,2)Consider the PMU buses as VΘ buses,3)Find the direct solution of power flow equations.Some study cases indicate that all of these methods would improve the power flow calculation more or less.
