摘　　要：针对山西阳城电厂至江苏淮阴500kV送出一期工程系统存在较严重的暂态稳定问题,利用电力系统仿真软件,分别以2005年华东福建互联后的整个详细网络和简化后的等值网络为研究对象,进行相应的机电暂态和电磁暂态2种模式下阳城送出的稳定计算。仿真结论表明,与固定串补相比,可控串补进一步提高了阳城送电的暂态稳定性能,通过减少故障引发暂稳问题时阳城电厂的切机台数而带来可观的经济效益。Aiming at the transient stability problem in the first stage of the Yangcheng-Huaiyin500kV power transmission project,The program system NETOMAC is employed for stability calculations of Yangcheng-Huaiyin transmission system.Taken the whole de-tail interconnected network of East China and Fujian province in the year of2005and its simplified equivalent network as the study system respectively,two different modes of simulations(electromechanical transient mode and electromagnetic transient mode)are carried out.The simulation results show that the TCSC scheme is more effective in improving the transient stability performance of Yangcheng-Huaiyin transmission system as compared with the fixed series compensation,and it will bring significant economical benefits by re-ducing the number of shed generators in Yangcheng plant when the transient stability problem is induced by the large disturbance.
