摘　　要：发电机组的计划检修作为防止机组老化失效的主要方法,在确保电力系统可靠运行方面起着重要作用。文中对市场环境下机组检修策略模型及算法进行了综述,并提出了进一步研究的问题。在市场环境下,制定机组检修计划时应当考虑系统运行的可靠性和发电公司的经济利益2个方面。通常,首先由发电公司确定本公司机组的计划检修时段,然后由独立系统运营商(ISO)考虑系统可靠性充裕度后按一定的原则调整机组检修计划;前者确保了发电公司的经济利益,体现了其独立的经济实体地位,后者保证了系统的安全可靠运行。对于该优化问题,一般采用遗传算法、模拟退火算法等启发式方法或者整数规划法、Benders解耦法等数学规划方法加以求解。Generator maintenance scheduling used to prevent units aging, is important to ensure power system operating reliably. The mathematical model and algorithm of generator maintenance scheduling are summarized in this paper. In power market, system reliability and economic benefit of generating companies should be considered simultaneously in generator maintenance scheduling. Usually, generating companies first determine their maintenance scheduling separately, and then independent system operator （ISO） regulates maintenance scheduling according to system adequacy constraints. In this model, the former problem ensures economic benefit of generating companies considered as the independent economic entities; the latter guarantees power system operating securely. Generally the optimization problems are solved with help of heuristic methods, such as genetic algorithm （GA） and simulated algorithm （SA）, or mathematical ones containing integer programming algorithm and Benders decomposition method.
