Processing method for solving section power flow out-of-limit by automatically searching adjustable unit based on section active sensitivity

The invention discloses a processing method for solving section power flow out-of-limit by automatically searching an adjustable unit based on section active sensitivity, and the method comprises the steps: carrying out the preconceived fault analysis of a user-defined fault set, and finding out a power flow out-of-limit section; automatically calculating the power flow out-of-limit section active sensitivity; automatically searching effective adjustable units according to the section active sensitivity; and verifying the practicability by adopting examples. According to the invention, N-1 and N-2 anticipated fault scanning can be carried out according to the user-defined fault set, the power flow out-of-limit section can be searched, section active sensitivity calculation can be automatically carried out, the regional adjustable unit can be searched, and an auxiliary decision is provided for section out-of-limit elimination. 本发明公开了一种基于断面有功灵敏度自动搜索可调机组解决断面潮流越限的处理方法，该方法包括：自定义故障集进行预想故障分析，找出潮流越限断面；自动计算潮流越限断面有功灵敏度
