一种基于主成分分析法及熵权法的中压配电网运行状态模糊综合评价方法
摘要：
本发明公开了一种基于主成分分析法并融合客观权重的中压配电网运行模糊综合评价体系。利用主成分分析法可以保留源数据中的主要信息，采用供电能力、供电质量以及经济性指标作为表征配网运行状态的源数据，通过求取相关系数矩阵的特征值和特征向量，从而确定配电网运行的主成分，形成一组相关性弱、而包络信息量大的评价体系。考虑到指标评价中存在模糊性，在体系内利用熵权法对新的评价指标进行客观赋权最终形成10kV配电网运行方式的模糊综合评价体系。本发明考虑了评价指标的模糊性，兼具定性分析和定量判断，具有一定的合理性和科学性。
摘要（英）：

The invention discloses an intermediate-voltage distribution operation state fuzzy integrated evaluation method based on a principle component analysis method and an entropy weight method. Major information in source data can be reserved by use of the principle component analysis method, a power supply capability, power supply quality and economic indexes are taken as the source data representing an operation state of a distribution network, through solving a feature value and a feature vector of a correlation coefficient matrix, principle components of operation of the distribution network are determined, and an evaluation system with weak correlation yet large envelope information content is formed. Given fuzziness existing in index evaluation, new evaluation indexes are objectively endowed with weights by use of the entropy weight method in the system, and a fuzzy integrated evaluation system of a 10kV distribution network operation mode is finally formed. According to the invention, the fuzziness of the evaluation indexes is taken into consideration, qualitative analysis and quantitative determination are realized, and the method provided by the invention is reasonable and scientific to a certain degree.
