摘要:运用电磁暂态仿真软件PSCAD/EMTDC,对复转矩系数法进行了时域仿真实现,并在实现过程中作出改进,对遇到的问题做了全面的分析并给出可参考的标准。最后以IEEE第一标准测试系统为研究模型,求取复转矩系数曲线,分析了线路串补度对电气阻尼的影响。分析结果可以为解决电力系统因串联电容补偿而引起的次同步振荡问题提供一些参考。

Abstract: The simulation of the complex torque coefficient method in time domain is realized with the electromagnetic transient simulation software PSCAD/EMTDC, and improvements are made in the implementation process. Comprehensive analysis and reference standards for the problems encountered are given too. Finally, the complex torque coefficient curves are obtained with IEEE first standard test system as the research model. The influence of the series compensation of circuit on the electrical damping is analyzed. The analysis results can provide some references for power systems solving the problem of sub-synchronous oscillation caused by series capacitor compensation.
Key words: PSCAD/EMTDC; complex torque coefficient method; sub-synchronous oscillation; electrical damping
