optimal PMU placement PMU优化配置
In chapter 3 and 4, the optimal PMU placement problems are discussed.
第三章、第四章着重讨论P MU优化配置问题。
For too high cost for PMU placement, the network is not observable only with PMU.
同时，由于成本原因，当前PMU配置还不能保证电网的完全可观测。
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.
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。进而讨论了以提高状态估计精度为目标的PMU配置方案。
