摘　　要：电力作为支撑工业社会经济发展的动脉血液,其安全问题直接关系到国家整个后工业化进程的推进速度。本文提出一种考虑本质安全的电网规划方案全寿命周期价值比选方法,该方法首先对网、源、荷等不确定因素进行建模;然后以减供负荷作为衡量本质安全的出发点,根据不同事故等级设置相应的触发本质安全惩罚系数,建立一种考虑本质安全的最小切负荷费用悲观值风险评估指标;最后将风险评估指标融入全寿命周期价值计算模型中,并通过建设特高压电网还是建设本地电源2种规划方案的对比验证了所提方法的可行性。As the artery blood to support the social and economic development,the power grid is directly related to the whole post-industrialization process.The paper presents an optimized method for power grid planning considering safety and value.Firstly,uncertain factors,such as the network,the source and the load,are modeled.Then,the load lost is used to evaluate the Essential Safety,and a penalty coefficient,which reflects the minimum loss of load considering Essential Safety,is established according to different accident levels.Finally,Other risk assessment indicators are integrated into the Life Cycle Value model,and the proposed method is verified by comparing the two plans of building UHV power grid or local power supplies.
