摘要
采用全过程动态仿真程序,对江西西部电网出现严重故障情况下的电压稳定问题进行仿真研究,分析了发电机励磁限制和有载调压变压器(OLTC)对电压稳定的影响,研究的稳定问题涵盖了暂态稳定问题和中长期动态稳定问题,使电力系统稳定分析更具有全面性。研究结果表明,严重故障情况下江西西部电网无功支撑不足,存在电压崩溃的风险,建议尽快建设江西西部500 kV环网。
This paper studies the voltage stability of the western Jiangxi power grid considering serious fault using full dynamic simulation software and analysis the influence of excitation limiter and on-load tap ehanger（OLTC） for long-term planning on dynamic voltage stability. The simulation of voltage stability contains the electric-mechanical transient process , long-term planning dynamic phenomena and made the stability analysis more comprehensive. The results show that the western Jiangxi power grid will experience voltage collapse because of lacking reactive power when it has serious fault.
