摘要
在满足合理的假设条件下,针对汽轮机的功角特性,采用非线性控制方法对功角进行控制,设计了一种效果比较好的非线性综合控制方法.以功角作为输出变量,通过稳定控制,减少了外界干扰对发电机功角的影响,保持了发电机在控制过程中的稳定运行,仿真结果表明所设计的非线性控制是有效和有实用性的.
According to the reasonable assumption,a novel nonlinear controlling method for the stability of the turbine-generator based on the theory of differential geometry is proposed.Applying the design scheme,the nonlinear output feedback control and the geometry theory are used in the control of the power angle,so the control law include the output target information.The output feedback control theory can make the power angle no variable by using an extra control variable.Simulation results show that the designed controller performs well for improving both power angle stability and dynamic characteristic of the generator terminal voltage.
