摘　　要：基于大电网差异化规划的原则和要求,综合全寿命周期成本理论和灾害经济学中的"有无对比"原理,提出一套差异化全寿命周期成本效益经济评估体系。考虑差异化规划的加强成本与减损效益并计及灾害发生时间和概率,建立了电网差异化规划经济性评估模型,提出了累计加强成本、期望净收益和收益成本比指标;综合考虑不同设备使用寿命和投运时间的差异,通过确定统一的研究时间周期,实现了差异化规划从设备级(单元件)到系统级(多元件)的经济性评估。最后通过Garver-6节点算例仿真计算结果验证了该评估方法的可行性和有效性。According to the principle and requirement of differentiated planning for large-scale power grid and through integrating the life cycle cost（LCC） theory and the ‘with and without comparison’ method in the disaster economics,a set of economic assessment system based on differentiated LCC effectiveness is proposed.Considering the strengthened cost and the benefit from loss reduction in the differentiated planning and taking the time and probability of disaster occurrence into account,an assessment model for differentiated planning of power grid is established,and the accumulated strengthened cost,the expected net proceeds and the benefit/cost ratio indicator are put forward.Comprehensively considering the differences among service lives and times of putting into operation of different equipments and by means of determining unified time period for the research,the economic assessment of differentiated planning from the level of equipment,namely the single component,to the level of system,namely multi components,is implemented.The feasibility and validity of the proposed assessment method are verified by simulation results of Garver’s 6-node system.
