摘要
结合同调分群与基于信息含量的方法,提出了一种转子角测量装置的优化配置方法。以发电机转子角响应的信息含量为性能指标,通过系统聚类分析将动态场景集压缩;同调分群并结合电气距离形成配置地点的候选集合;以Gramian行列式作为信息含量的表征,采用Tabu搜索算法从候选集合中有效地求得最优解或次优解。实际系统的仿真结果表明了这种配置方法的合理性和有效性。
Combining coherency identification with infor-mation content, an optimal placement method of rotor angle transducers is proposed in this paper. Based on generator rotor angle responses, raw dynamic scenario set is compressed through hierarchical clustering analysis. Incorporating coheren-cy identification with electrical distance measure, placement candidates are formed for each scenario of the compressed set. Using Gramian determinant as the information content measure, a tabu search algorithm is implemented to find the optimal or nearly optimal placement sites from the candidates. Simulation results of an actual power system demonstrate its rationality and effectiveness.
