摘要
针对发电机及其励磁系统的数学模型及参数对电网动态稳定分析结果的影响,选取2007年安徽电网夏季高峰方式数据文件,采用中国电科院版动态稳定仿真程序,对影响电网动稳定较大的几个因素分四种方案作了详细计算分析,指出采用不同的发电机励磁系统模型及参数,动态稳定分析结论差别较大,其中实测模型参数最多的方案计算结果与实际运行工况基本接近,且随着电网规模的扩大,电网内发电机使用经典模型及经典参数会使动态稳定分析结果失真。
The paper studies the influence of generators based on detailed excitation system models and paramenters to power grid dynamic stability by thePSD-SSAP software published by CEPRI.This paper analyzes some main factors by four schemes ,which engenders biggish error to system dynamic stability selecting 2007 Anhui power grid. The results show that the most one of the detail models and parameters leading to the conclusion is close to fact run condition .With the Grid scale spreads quickly, the classical models and parameters seem to bring result distortion.
