| 摘 要： | 针对目前监视控制和数据采集(supervision control and data acquisition,SCADA)系统和广域测量系统(wide-area measurement system,WAMS)量测数据的特点,提出了一种计及相量测量单元(phasor measurement unit,PMU)的量测量变换状态估计。文中利用量测量变换方法,将SCADA和WAMS下的各类量测转化为等效电压量测,经简化处理得到了常实数信息矩阵,实现了节点电压实部、虚部的解耦计China(NSFC)(50177066).算。该算法具有计算速度快的特点,克服了传统量测量变换状态估计只能处理单一支路功率量测的弊端。IEEE30节点系统算例验证了所提方法的有效性。

| Abstract: | According to the features of measured data acquired from current supervisory control and data acquisition (SCADA) and wide-area measurement system (WAMS) respectively,a state estimaiton on measured quantity transformation in which the phasor measurement unit (PMU) is taken into account is proposed. Using transformation of measured quantity,all kinds of measurements by SCADA and WAMS are transformed into equivalent voltage measurement,and after simplification a constant real number information matrix is obta... |
