风险评估在电网检修中的应用探讨

在电网检修过程中,必然涉及到断路器的倒闸操作,不同的倒闸操作的选择,可改变潮流分布进而也会改变系统运行风险。通过工程中典型的例子,利用概率统计的方法进行计算,并将结果进行了比较分析。优选出最有利的方案,从而能够有效控制潮流分布,降低在倒闸操作过程中系统运行的风险。电网系统运行规划工程人员参照该方法可以进行类似的风险评估。

Discussion on Application of Risk Evaluation in Examination and Repairment of Electric System

In the overhaul process of a power grid,the switching operation is essential.However,the different choice of the switching operation will change the trend distribution,and therefore also change the operation risk of a system.Here,through the engineering example,using the calculation method of probability and statistics,and by the comparative analysis of the results,the most beneficial programs are optimized in order to control the tide distribution effectively,and reduce the operation risk of the system dur...
