【摘要】 提出一种新的相量测量单元(PMU)配置优化算法,在关联节点可测的基础上,引入PMU优选约束,建立以可测关联节点与假设安装的适配指标为目标函数的网络覆盖模型。采用适应型Petri网分析方法,先将复杂网络分解为若干基本分析单元,从而缩小了分析规模;然后引入标识算子,将复杂矩阵运算转化为逻辑运算,简化推理过程;同时,通过更新变迁点火序列进行PMU地点选择,并引入变迁时间标签使计算过程得以简化,提高了计算效率。最后通过算例仿真,验证该方法计算准确,过程简便。更多还原

【Abstract】 A new optimization algorithm for phasor measurement unit(PMU) placement is introduced in this paper.The net-covering model is built based on suitability of the observable associated nodes and the choice of PMU location.Then based on the information of connection nodes,the whole power network is analyzed with improved Petri net.The complex power network is divided into several parts,the change enabling array is renewed,and the marking operator is used.The analysis scale is reduced and the inference process is simplified.Finally,from the testing results of several methods with the actual data of the real power network,it is concluded that the method proposed is relatively accurate and the processes of calculations are feasible and convenient.更多还原
