摘　　要：在分析国内外开展电力变压器状态维修工作现状的基础上,提出了一种确定变压器状态维修策略的灰局势决策方法。该方法以立即停电检修、优先安排检修、监视运行、定期检修和延期检修等5种典型维修方案作为变压器状态维修的对策集;在兼顾安全性和经济性的基础上,给出了安全性、可靠性、维修性、经济性以及可监测性等5个定性的决策评价指标及相应的指标量化方法;构造了变压器状态维修策略的灰决策局势效果向量,并以局势效果向量和最优局势效果向量的灰色绝对关联度为决策依据进行最优维修方案的决策。决策实例说明了该方法的具体实现过程,并验证了其有效性。Based on the status of CBM （Condition Based Maintenance） in domestic and abroad,the authors propose a GSDM （Grey Situation Decision-Making） method of CBM strategy for power transformers. The countermeasure set of CBM for power transformers includes the five typical maintenance schemes,such as the off-line maintenance,priority plan overhaul,surveillant operation,periodic overhaul and postponed overhaul. Taking the safety and economy into account,the five qualitative evaluation indexes of decision making,such as security,reliability,maintainability,economy and monitoring feasibility,are proposed,and the quantitative method of the qualitative evaluation indexes is presented. Through constructing situation effect vectors of GSDM,the optimal maintenance strategy for power transformers can be obtained on the base of the grey relational grade between the situation effect vectors and the optimal situation effect vectors. The examples of the CBM scheme for two power transformers in service are provided to illustrate the specific process of the decision making method and to verify its effectiveness.
