    摘 要:电力系统稳定器 (PSS) 参数整定试验过程操作复杂且过多依赖试验人员经验。针对国内普遍应用的 2 型 PSS,提出一种基于最优补偿特性的 PSS 控制参数自适应拟合方法。分析了 PSS 的最优补偿特性,在考虑运行约束的条件下,建立了以补偿特性与最优补偿特性方差最小为目标的 PSS 控制参数自适应拟合模型,该模型可自动匹配发电机组励磁系统的无补偿特性,在一定误差范围内寻求 PSS 最优的控制参数。编写程序算法求解,实现了 PSS 控制参数的快速计算。实际工程应用表明,应用该方法计算的 PSS 参数控制效果良好,具有良好的工程应用价值。

    Abstract: The parameter setting test of power system stabilizer (PSS) is complicated and is dependent too much on the experience of test personnel. An adaptive fitting method for 2 PSS control parameters based on optimal phase compensation is proposed because of repeated iteration and verification for the traditional 2 PSS parameter tuning. The optimal phase compensation characteristic of PSS is analyzed. Then an adaptive fitting model of PSS control parameters with minimum variance between compensation component and optimal compensation is built under the condition of limited performance. This model can automatically match the frequency characteristic of the excitation system of generator sets to find the optimal PSS control parameters within a certain error range. The programmed algorithm is written to achieve fast calculation of PSS control parameters. The practical application shows that this method is of great use to calculate the controlling effects of PSS parameters, and of great value to be applied.
    Key words: power system stabilizer; parameter fitting; optimal phase compensation; adaptive
