摘　　要：在对全寿命周期成本(life cycle cost,LCC)理论进行系统研究的基础上,分析继电保护装置技改工程的实际特征和本质特点,构建了继电保护装置技改工程的LCC模型,以及基于固定效益法和LCC的继电保护装置技改策略模型;搜集计算LCC所需的相关数据,计算了继电保护装置技改工程在不同影响负荷水平下的LCC和费用年值,从而得出继电保护装置的经济寿命和寿命期内故障后的技改策略。On the basis of systematic study on life cycle cost （LCC）theory,the paper analyzes practical characters and essen-tial characteristics of technical transformation projects of relay protection devices.LCC model for technical transformation of relay protection devices is established and the model for technical transformation strategy of relay protection devices based on fixed benefit method and LCC is constructed;relevant data that required by LCC is collected and calculated;LCC and annual cost of technical transformation projects of relay protection devices under different influencing loads are calculated. Therefore,economic life of relay protection devices and technical transformation strategy after faults occur in the life cycle are concluded.
