摘要
发电机励磁系统参数设置的合理与否对电力系统的静态稳定性和暂态稳定性有显著的影响。首先应用遗传算法(GA)分别按照时间乘绝对误差的积分(ITAE)和误差平方积分(ISE)准则对龙山电厂励磁系统的参数进行了优化。然后对优化后所得的励磁系统,进行了小信号特性仿真和频率特性分析,并在PSASP下用华北网数据进行了大信号特性仿真试验。仿真计算结果表明,整定优化后的励磁系统具有良好的动态性能,从而验证了整定优化参数的合理性和正确性。
The excitation system parameters of Longshan power plant are optimized according to the ITAE and ISE principles with Genetic Algorithm technology. The small signal performances simulation test is conducted. The frequency characteristics are analyzed, The large signal performances simulation is tested based on the data from North China power grid with PSASP. The calculation results of simulation show that the optimized system is feasible.
