摘　　要：实现电压暂降治理的市场化,需解决降低治理投资成本和合理制定服务费用两大问题。首先提出一种基于过程免疫时间(process immunity time,PIT)的全过程电压暂降风险量化方法;在此基础上,结合暂降治理服务成本,提出一种考虑最大化去风险的电压暂降治理设备优化配置模型,实现满足用户需求的最优治理服务方案决策。引入满意价格策略,定义供、用电双方的满意度,明确其利益诉求,提出一种基于双方满意的电压暂降治理增值服务定价模型。最后,以中国某化工厂为例,通过实例验证所提方法的正确性和合理性,所提方法有助于电压暂降治理增值服务的推行,进而解决用户的电压暂降问题,缓解供用电双方矛盾,具有较大的实用价值。For realizing marketization of voltage sag governance,two major problems need to be solved:lowering the investment cost and reasonably setting the service fee.A method for whole-process voltage sag risk quantification is thus proposed based on the process immunity time(PIT).Combined with the service cost of sag governance,an optimal configuration model of voltage sag governance equipment considering maximum risk removal is proposed to realize the optimal governance service scheme decisionmaking to meet the needs of users.On the basis of introduction of the satisfactory price strategy,definition of the satisfaction degree of both power supply companies and users,and clarification of their interest demands,a value-added service pricing model of voltage sag governance is proposed based on mutual satisfaction.Finally,taking a chemical plant in China as an example,the feasibility and rationality of the proposed method are verified through case study.The proposed method is helpful to the implementation of valueadded service for voltage sag control,thus solving the voltage sag problems of users and alleviating the contradiction between power supply and consumption,which is of great practical value.

关 键 词：电压暂降 定价 风险评估 治理服务 双方满意
