通过对我国电网运行安全性的分析,提出了简便实用的电网运行安全性评价的指标体系,该体系从结构安全、运行安全、可靠性、充裕性四个方面进行构建,并利用极值法、变异系数法、综合线性评分法建立了评价模型,对电网运行安全性进行综合评价,进行了实证分析应用。
According to the analysis of the safety of power grid operation in China,this paper puts forward a simple and practical index system of power grid operation safety evaluation which includes structural safety,operation safety,reliability and abundance.Then the extreme value method,the coefficient of variation method,and the integrated linear scoring method were used in this paper to establish evaluation model which evaluates the safety of power grid operation and some examples were analyzed and applied.
