摘　　要：结合PSS抑制电力系统低频振荡的基本原理及PSS参数整定原则,介绍了瑞士ABB公司UNITROL5000励磁调节器PSS的基本构成和电路数字模型。分别采用ABB厂家提供的PSS参数和现场试验所得的PSS整定参数对内蒙古岱海发电厂1号机励磁调节器的PSS进行验证试验。经过在线有补偿相频特性、负载阶跃干扰试验结果的比较,表明采用现场整定的PSS参数抑制低频振荡效果优于厂家提供的PSS参数,机组长期运行的PSS参数应按现场整定的值设置。Combination of fundmental principles that PSS prevents oscillation from low frequency and setting priciples for PSS parameters, basic construction and circuit digital model of UNITROL5000 excitation adjuster which is made in Switzerland is introduced. PSS of Unit 1 in Inner Mongolia Daihai power plant is tested with the parameters supplied by ABB Company and the parameters supplied by field-test respectively. It is showed that the field-test parameters are better than the parameters supplied from ABB Company with the online compensating phase-frequency characteristic and a step interference test. Parameter setting of PSS in unit generator running must be set according to the field-test setting.
