线性多变量控制

(1)强力式励磁调节器。早在50年代中期，前苏联提出了强力式励磁调节器，除 了采用发电机端电压偏差ΔUt外，还采用发电机频率偏差Δf及其一次微分和发电机定 子电流及其一次微分等辅助反馈变量。在设计上采用“双变量D域划分法”。这种调节 器具有在保证调节精度下稳定励磁、提高发电机动态与暂态运行稳定性、抑制系统事故 后的振荡等功能，在前苏联得到推广应用。但由于设计方法不方便，共同稳定域很小， 参数整定困难等原因，在国际上和我国均未普遍应用。

(2)?电力系统稳定器PSS。它是在PID调节器的基础上，附加发电机的转速偏差 Δω、功率偏差ΔPe、频率偏差Δf中的一种或两种信号的二阶超前校正环节作为附加控 制。其作用是，增加对电力系统机电振荡的阻尼，以增强电力系统的动态稳定性。有资 料说明，采用PSS可将系统极 限运行角提高到110°～120°。 以Δf(Δω) 为附加信号的 PSS控制器传递函数结构图如图3所示。

我国引进设备所采用的 PSS的传递函数结构图见图4。采用了WASH—OUT 滤波器，保证在任何情况下，直流分量附加到调节器控制回路中。两个放大因子KSS1和KSS2“加权”用计算机程序?计算。设定值取决于机组参数、机组运行点及网络阻抗，从而决定其相位超前和滞后以 及稳定信号的幅度，以求所有运行点都达到好的阻尼效应。
