| 摘 要： | 建立了电力系统稳定计算用汽轮机及调速系统的数学模型并对其进行了适当的简化.频域分析和时域仿真表明,不同参数配置下的汽轮机调速系统对电力系统的影响不一样,它可能增加系统的阻尼,也可能减小系统阻尼.放大倍数不改变系统的分界频率,但阻尼大小、时间常数和纯延时等非线性环节是影响分界频率的主要因素.汽轮机调速系统对电力系统阻尼特...

| Abstract: | The mathematical models of turbine governor are established and simplified for the stability calculation of power system.The frequency domain analysis and time domain simulation indicate that different parameter configurations of turbine governor have different influences on power system,increasing or decreasing its damping.The magnification change has no influence on boundary frequency while the nonlinearity of damping,time constant and pure time delay are its main influencing factors.The impact of turbine... |
