基于抗震韧性评估的220kV变电站修复及改造策略
Recovery and Retrofitting Strategies for 220 kV Substations Based on Seismic Resilience Assessment
摘要
Abstract
The seismic disaster survey shows that substation has higher vulnerability under the strong seismic ac-tion,which significantly affects post-seismic disaster recovery and rescue efforts.In this paper,a 220 kV substation is taken as a case study to perform the sampling simulation of the system disaster,and the mixed integer linear pro-gramming(MILP)is used to generate optimal repair decision sequence.In this study,the MILP decision result is used to train an artificial neural network(ANN)model.The repair strategy based on the model is proposed and is suit-able for scenarios which is lack of high performance calculation condition.Then,the repair priorities for various com-ponents of substation after the seismic is analyzed,which can achieve the repair strategy in case of unknown fault po-sition after the disaster.Finally,the seismic resilience retrofitting of substation is performed by using three distinct retrofitting strategies.The result shows that compared to MILP strategy,the ANN-based repair strategy can significant-ly reduce computational costs while maintaining the efficiency of repair decisions.In addition,The optimal retrofit-ting strategy with different budget is given.The effectiveness of the repair strategies and retrofitting strategies pro-posed in this paper are verified by those results.关键词
