摘要
基于GPS的同步相量测量单元 (PMU)是一种新型的高精度测量装置 ,能够测量母线电压相量。该文提出了在传统的SCADA量测系统的基础上 ,部分地安装PMU以后混合量测系统的状态估计模型。基于此模型 ,可定量地分析引入PMU以后对状态估计精度的改善程度。
GPS based synchronous Phasor Measurement Unit (PMU) is a new type of measure unit with high precision. The modeling of a hybrid measurement system is proposed which includes traditional SCADA measurements and partially equipped PMUs. Based on the model, the precision improvement of state estimation due to incorporation of PMUs can be analyzed quantitatively and the scheme of PMU placement can be established.
