摘要
DDRTS数字仿真系统能准确模拟电力系统电磁暂态和机电暂态过程,成为研究电力系统规划、设计及运行的有力工具,同时也是继电保护装置、安全自动装置及测量和控制装置实时闭环测试的技术平台。文章以群科变电所2.4事故为例,利用此系统对110 kV群科变SEL保护动作行为进行仿真试验分析,查明了引起保护拒动的原因,排除了事故隐患。
DDRTS（Digital Dynamic Real Time Simulation）system can accurately simulate electromagnetic and electromechanical transient process. It becomes a useful tool for studying plan, design, and operation of power system; also it＇s the real time closed loop test technology platform of relay protection device, automatic safety device, and measuring and control device. The paper takes the 2.4 accident of Qunke substation as an example, and makes simulation test analysis on SEL protection behavior of 110kV Qunke substation by using DDRTS system, then finds out reason of protection failure, and eliminates hidden trouble of accident.
