摘要
详细阐述了PSS参数整定基本原理,并针对在我国抽水蓄能电厂广泛应用的奥地利VATECHELIN公司THYNE6型励磁系统的PSS模型以及按照IEEEStd421—PSS2A标准构建的PSS模型进行了分析及对比。对按照IEEEStd421—PSS2A标准构建PSS模型的机组以及采用THYNE6型励磁系统的PSS参数整定试验过程、无补偿频率测试数据、仿真计算后相频特性数据以及PSS参数设置后的发电机PSS效果校核试验波形图等进行了说明、分析以及计算。对α/p型PSS仿真计算软件的计算参数选择以及在仿真计算前后的发电机阻尼比进行了对比性计算。该仿真计算软件研制成功为PSS现场参数整定试验提供了强有力的手段和方法。
Principle of PSS parameter setting is described in detail. Austria VATECH ELIN’s THYNE6 excitation PSS model widely applied in pumped storage power station in China and IEEE Std 421-PSS 2A’s PSS model are compared and analyzed. Introduction, analysis and computation are done for Zhaoshi power plant #1 generator and Heimifeng power plant #4 generator. These include PSS parameter setting test process, reactive compensation test data, simulation angle and frequency data and setting of generator PSS test wave diagram. Contrast computation is conducted for computation parameter selection of a/p PSS simulation computation software and the damping ratio of generatiors before and after Heimifeng #4 generator simulation. The simulation computation software is developed successfully, which provides powerful means for PSS on site parameter setting test.
