| 摘要:
采用传统频域方法进行电力系统稳定器(power system stabilizer,PSS)参数设计时只考虑本机组的运行,忽视了电网的整体运行情况。为此,文章基于降阶选择模式分析法对PSS参数进行优化,形成了系统的降阶状态方程。通过计算状态方程特征根与状态变量的相关性及灵敏度,确定了PSS的配置点。文中的方法不必计算系统全部特征根,所需的计算时间较少。针对新疆实际电网,文章还进行了PSS参数设计,确定了PSS的安装地点及安装机组,仿真结果表明文中的PSS抑制振荡的效果良好,验证了文中方法的正确性和有效性。 | |||||||||||||||||||||||||||||||||||||

| Abstract:
When traditional frequency domain method is adopted to design the parameters of power system stabilizer (PSS), only operation conditions of the unit using this PSS are considered, and the global operation conditions of power grid are ignored. For this reason, based on order reduction selective mode analysis the PSS parameters are optimized to form order reduction state equation of system. By means of calculating the correlativity and sensitivity between eigenroots of state equation and the state variables, the configuration point of PSS is determined. Using the proposed method it is not necessary to calculate all eigenroots of the system, so less calculation time is required. For Xinjiang power grid, the authors design the PSS parameters and determine the place to install PSS as well as the generator to be equipped with PSS. Simulation results show that the designed PSS can effectively suppress oscillation, thus the correctness and effectiveness of the proposed method are verified. | |||||||||||||||||||||||||||||||||||||
