摘要
本文根据光照水光互补工程的电气接线方案,结合工程七种运行工况,拟定过电压计算的仿真计算模型,采用电力系统电磁暂态过程模拟软件,分析研究了雷电侵入波过电压、特快速暂态过电压、单相接地故障、甩负荷等故障情况下的工频过电压、断路器三相合闸和单相重合闸时的操作过电压计算成果,为工程安全稳定运行提供可靠的依据。
According to the electrical wiring scheme of the light,water and light complementary project,combined with the seven operating conditions of the project,a simulation calculation model for overvoltage calculation is proposed.Using the electromagnetic transient process simulation software of power system,the calculation results of power frequency overvoltage under the conditions of lightning intrusion wave overvoltage,ultra fast transient overvoltage,single-phase grounding fault,load rejection and other faults,and the switching overvoltage during three-phase closing and single-phase reclosing of circuit breakers are analyzed and studied in this paper,Provide reliable basis for safe and stable operation of the project.
