提出了一种检修修正法，通过以待编机组总检修系数对月度需求进行反向修正、各机组检修系数对发电能力作正向修正，进而获得年度合同分月分解的最佳因子。此法获得的月度计划保证机组间年度进度一致，满足月度总需求，同时各机组间电量分配均衡，便于调度控制。该方法在浙江省电力公司已有5年实践经验，对电网各种情况均有较好的适应性。%This paper proposes a practical "maintenance revising method", which conducts reverse correction on monthly demand through total maintenance coefficient of units to be encoded and positive revision on gen-erating capacity through the maintenance coefficient of each unit, and then the optimum factor of monthly de-composed annual contract is obtained. The monthly schedule achieved by this method can guarantee consis-tent annual schedule among units and meet the monthly total demand. Meanwhile, the electricity distribution of each unit will be balanced so that electricity can be dispatched and controlled conveniently. This method has been applied in Zhejiang (Provincial) Electric Power Corporation for five years and is of nice adaptability for various power grid conditions.
