| Planned maintenance of power grid equipment is an important means to ensure the safe operation of power grid.Whether the maintenance plan is reasonable or not directly affects the security,reliability and economy of power grid operation,and even has a great impact on the whole social life.At present,the research object of optimization algorithm of equipment maintenance plan mainly focuses on generator maintenance arrangement,while the main object of urban power grid maintenance plan is line and transformer,and the topology structure of urban power grid presents radial attributes of distribution network.All these lead to the particularity of optimization method of urban power grid maintenance plan,aiming at the optimization of urban power grid maintenance plan.Methodological research is very necessary.In this paper,according to the actual situation of maintenance work,the optimization model of urban power grid maintenance plan is proposed.At the same time,through the comparison of several intelligent algorithms,Tabu Search method is selected as the most basic algorithm.Combining with the current maintenance mode in actual work,the electrical-related maintenance equipment is packaged,which greatly simplify the calculation process of optimization algorithm.At the same time,the practical feasibility of the optimization results is ensured from the source of optimization,which makes the optimization algorithm more suitable for the optimization of urban power grid maintenance plan.At the end of this paper,the improved Tabu Search algorithm is applied to a maintenance plan of urban power grid,and better application results are obtained.It provides a basis for further improving the optimization of the maintenance plan of urban power grid. |
