智慧型电力应急预案模式在故障线路快速定位方法中的应用研究

Application research on fast location method of fault line based on intelligent power emergency plan mode

现有电力应急预案在响应突发事故导致的输电线路故障情况时,体现出准确性和时效性的明显不足问题,归其根本是因为在响应初期无法做到准确及时地定位出故障线路位置,从而使得应急响应存在滞后性。而智慧型电力应急预案以事故的推理机制为基础,在考虑系统的状态运行条件下,实现无脚本的动态应急响应。在智慧型应急预案下,动态应急响应的关键在于准确及时地定位出发生故障的输电线路位置。通过将电力网络的APTS简化模型和改进遗传算法相结合,构建出一种在智慧应急预案下的故障线路快速定位方法。该方法具有定位速度快和定位精度高的优点,具有很强的实用性。最后,以广州市某小型配电网为例验证了其合理性和可行性。

In response to the transmission line fault caused by the emergency accident,the existing electric power emergency plan reflects the obvious shortage of accuracy and timeliness.The reason is that the location of the fault line can not be accurately and timely located at the initial stage of response,which makes the emergency response lag.The intelligent power emergency plan is based on the reasoning mechanism of the accident,and realizes the dynamic emergency response without script under the condition of considering the state operation of the system.Therefore,under the intelligent emergency plan,the key of dynamic emergency response is to accurately and timely locate the fault transmission line location.In this paper,by combining the simplified APTS model of power network with the improved genetic algorithm,a fast fault line location method under the intelligent emergency plan was constructed.This method has the advantages of fast location speed and high location accuracy,and has very good performance Strong practicability.Finally,this paper took a small distribution network in Guangzhou as an example to verify its rationality and feasibility.
