A Research Of Equipments Maintenance Optimization For Baotou Power Supply Bureau

With the supernormal and leap-forward development of the construction of BaoTou Power Grid, the problem how to optimize equipments maintenance scheduling considering the state of equipments becomes very imperative for improving the security and economy of power supplying. In the paper, the way of making maintenance scheduling nowadays is introduced and analyzed in detail, also, condition-based maintenance and state evaluation are studied and introduced, based on which, a way to evaluate the state of power supply equipments numerically by using Fuzzy Comprehensive Evaluation Method is proposed. By analysing the maintenance scheduling, a model to optimize power equipment maintenance considering equipment state in its objective function is proposed, which is more in line with the needs of BaoTou Power Supply Bureau at present. The model is considered to be solved using genetic/tabu search hybrid algorithm. The case using data of Baotou Power Supply Bureau verified the proposed model. The proposed optimization model makes the maintenance take the state of equipments into consideration, which can not only minimize the outage cost, but can improve the operation safety of equipments also, so as to improve system reliability and social and economic benefits of power supply company.
