摘要
针对阳城—淮阴远距离输电工程中暂态稳定性问题突出的实际情况,考虑到可将现有的固定串补改为可控串补(TCSC),然后利用能量函数控制策略对TCSC实施控制以提高系统暂态稳定性。介绍了通过NETOMAC仿真软件对控制策略进行的仿真研究,给出了2005年实际简化系统的仿真结果并与动模实验进行了对比。仿真表明,当固定串补改造为可控串补后,TCSC可明显减少切机的概率,大大地提高了系统暂态稳定性,具有重大的工程实用价值。
For the Yang Cheng-Huai Yin long distance transmission project of China,it's considered to replace current Fixed Series Compensation (FSC) with Thyristor Controlled Series Compensation (TCSC) based on the energy function control strategy for the transient stability enhancement of the power system.This paper first validates the proposed control strategy with NETOMAC program and compares the results with those of the physical experiment.Then,the simulation results of the simplified East China power network of 2005 are presented.All the results indicate that the probability of generator shedding is obviously reduced and the transient stability is greatly improved when FSC is updated to TCSC.Therefore,this research work is of significant engineering value.
