| 摘 要： | 随着电网综合变电站的数目的日益增加,电网必须动态调整综合变电站的负荷特性分类结果.针对不断新增和变化的变电站的负荷特征数据,提出了基于数理统计的综合负荷特性多总体距离判别法,该方法以马氏距离作为多总体距离判别依据,以误判率来检验判别结果的准确性.通过某电网已知的实际变电站负荷特性,对待判别的变电站进行总体距离判别,得出...

| Abstract: | With the number of synthesis substations growing,power system must dynamically adjust the substation classification result of load characteristics.The multi-distance criterion method of synthesis load characteristics based on mathematical statistics is presented in the paper for the new and changing load characteristics data of substations.The method is based on the Ma-distance,,and can improve the accuracy by testing misjudgment rate.Through a example of actual grid substation load characteristics,the accurate results can be obtained which use the multi-distance criterion to judge the substation,and the effectiveness of the method is demonstrated. |
