摘　　要：针对分布式电源广泛接入的主动配电网馈线自动化评估问题,提出一套主动配电网馈线自动化动作效果评价方法。首先定义了配电网馈线自动化过程中的负荷状态,并细致分析了主动配电网中馈线自动化动作干扰因素。之后,综合考虑动作过程和动作结果,提出了7个馈线自动化动作效果定量评价指标,并建立了主动配电网馈线自动化动作效果评估体系。基于无失效测试法改进了配电网馈线自动化动作评估方法。最后,以某双环网线路的馈线自动化系统为例,验证了本文方法的有效性,该动作效果评估方法也可扩展应用于配网自动化中其他动作效果的评估。Wide access of distributed generation introduces a new challenge to the traditional feeder automation(FA)evaluation method.Given this background,an evaluation method of the feeder automation(FA)for active distribution network is presented.Firstly,the load states during the fault location,isolation and restoration process are elaborately defined and the interference factors affecting FA are systematically researched.Secondly,the FA action evaluation method is proposed,including seven evaluation indexes from two aspects of action process and action result,respectively.Subsequently,the comprehensive evaluation method of the action effectiveness for the FA in the active distribution network is improved based on the failure-free evaluation test method.Finally,a FA system with double loop network is employed to demonstrate the effectiveness of the proposed evaluation method.
