摘要
分析了一台114MW 水轮发电机采用线性最优励磁控制器的现场试验情况。试验表明,由于参数调整不合理,该控制器性能不符合要求,较原PI+ PSS调节器的性能差,不能起到提高系统稳定性的作用。文章指出,制造厂必须提供励磁系统的实际数学模型和参数,数学模型中的参数必须便于查阅。
The commissionning test of a linear optimum excitation control(OEC) is reviewed and compared with the old PI+PSS excitation controller. The performance of the OEC cannot meet the requirement of the power system, and is not as good as the PI+PSS excitation controller.In this paper aleo show fhat,the merhmahic model shonld he qlered by manugacfarer,and the parameters of the modcl showed he eacy to check by ucer.So that the ucer ean review and calaulat the perqormanc of the exefafcon system.
