摘要: 孤岛的判别与处理对电力系统可靠性评估具有重要意义,为了提高孤岛判别与处理的速度和精度,提出一种基于Matlab和Matpower的孤岛处理与判别方法,该方法根据孤岛的性质利用Matlab建立孤岛判别矩阵,并对Matpower中参数进行修改,使Matpower能够对孤岛系统直接进行直流潮流计算。相较于之前的人工计算,该方法不仅在速率上得到较大的提升,而且具有较高的准确性和可操作性。适用于电力系统的可靠性评估过程中的孤岛判别与处理。

关键词: 孤岛, 可靠性评估, Matlab, Matpower, 直流潮流计算

Abstract: Island judging and processing is of great significance in power system reliability assessment.In order to improve the island judging and processing speed and accuracy,an island judging and processing method based on Matlab and Matpower is proposed.The method uses Matlab to establish the island discriminant matrix according to the nature of the islands,and then modifies the parameters in the Matpower for the Matpower to perform directly dc power flow calculation of the island system.Compared with the conventional manual calculation,this method offers higher speed as well as better accuracy and operability.

Key words: island;reliability assessment;Matlab;Matpower;dc power flow calculation
