摘　　要：设计了考虑电力系统安全的输电网规划流程,改变了传统规划只考虑N安全和N-1安全的规划模式,进一步计算分析了规划网络在N-2安全情况下的缺电成本。文中采用故障筛选再规划的方式提高了N-1安全规划的计算速度,实现了大规模规划问题的求解,满足工程应用需要。18节点系统及实际电网147节点系统的计算结果表明,该方法行之有效。The process of transmission network planning considering the electric power system security is designed in this paper. It has renovated the traditional planning method in which only N secure rule and N-1 secure rule are considered, and the load shedding costs of the planning network in N-2 condition are further analyzed. The fault selection step is first carried out so that the computing of the N-1 security network planning can be speeded up and the large real network planning can be realized meeting the demand of engineering applications. Tests on the 18-bus system and a real power network of 147-bus system show that the method proposed is effective.
