摘要
为了提高电网安全稳定分析的有效性和适应性,本文从发电机及励磁系统角度,选择小机组(单机容量在50MW以下)集中的安庆地区电网实时网架及运行实况,使用中国版PSD-BPA稳定分析程序,针对从110kV接入系统的小机组对220kV主网暂态稳定水平的影响进行了专项研究。研究结果表明,从110kV接入系统的小机组对主网的暂态稳定性影响不大;发电机及励磁系统采用详细模型计算安庆地区电网暂态稳定水平结果比采用恒定模型计算安庆地区电网暂态稳定水平结果要高。
In order to advance the effectuality and adaptability of grid safe reliable analysis, selecting Anqing area,the paper studies speeially the influenee about the small- load generators used exeitation system based on detailed models to the 220kV main grid through the BPA soft and theory reasoning . The result shows that the small - load used excitation system based on detailed models can hardly influence the transient stability of 220kV main grid, and it can improve the transient stability of the 110kV area grid apparently.
