摘要: 利用可靠性成本/效益分析方法可以有效地处理好电网供电可靠性与电网建设经济性两者之间的关系。从工程实用角度阐述了可靠性成本和可靠性效益的各部分组成及计算方法,在对输电网可靠性进行定量评估的基础上,将可靠性成本/效益分析方法应用于实际电网。对华东某地区2005年、2010年以及2015年的220 kV和500 kV电网规划方案进行了分析计算,利用改进的产电比法估算各年份电网的缺电成本,分析比较了各年份电网扩容建设后在供电可靠性和成本/效益方面的差异。研究结果对供电网规划与建设具有参考价值。

Abstract: The reliability cost-benefit analytical method can be used to well deal with the relationship between power supply reliability and the economy of network construction. The composition and calculation method of reliability costs and reliability benefits are described in this paper. On the basis of a quantitative evaluation of the power supply reliability, the reliability cost-benefit analytical method has been applied to the power grid. An analysis is made on the 220 kV and 500 kV network planning schemes of one certain area in East China of the year 2005, 2010 and 2015. By using the improved ratio of output value to unit electricity consumption method. each year’s unserved energy costs are estimated, and the difference in power supply reliability and cost/benefit are compared after power grid expansion. The result can provide references for network planning and construction.

Key words: Transmission grid, cost-benefit analysis, reliability evaluation, unserved energy cost
