摘要
本文在研究并分析磁饱和式消弧线圈工作机理的基础上,在PSCAD/EMTDC仿真软件中设计了磁饱和式消弧线圈模型、励磁控制系统等仿真模型,并对中性点经消弧线圈接地系统的各种运行状态进行了仿真研究。仿真试验结果表明:本文建立的仿真模型是合理的、有效的;补偿电网采用磁饱和式消弧线圈快速合理地补偿了电容电流,能促使接地电弧快速自熄。
A design on magnetically saturated controllable reactors model,a zigzag grounding transformer model design and an excitation control system model design is realized with the PSCAD/ EMTDC simulation software based on analysis and studies to principles of magnetically saturated controllable reactors At the same time,the simulation research to each kind of running status of the resonant grounding system has been carried out.The simulation test result has indicated that the simulation model is reasonable,effective and compensating networks quickly and effectively compensate capacitive current with the magnetically saturated controllable reactors,which is able to quickly extinguish the arc.
