摘要
由于重型工业企业及大型用电设备的不断增多,对电网形成了越来越强烈的冲击负荷,严重影响电力系统的稳定性。提出用大型发电机的非线性最优励磁控制这种新型的控制手段,抑制冲击负荷的影响。对四川电网的仿真计算结果表明,非线性最优励磁控制能迅速抑制冲击负荷引起的系统振荡,提高输电线路传送的有功功率,良好地改善冲击负荷对电力系统稳定性的影响。
Because of development of heavy industry and increase of large power equipment. more intensive percussive load is formed in power network and influences stability of power system seriously. As a new control means, nonlinear optimal excitation control (NOEC) can improve effect of percussive load on stability of power system effectively. The simulation results of Sichuan Power Network demonstrate that NOEC can attenuate oscillation caused by percussive load rapidly, increase power conveyed by transmission line.
