摘要
本文提出一种设计多机电力系统优化变结构AGC控制器的新方法。各子系统的滑行平面只选取本子系统的状态量,控制器采用新的结构,详细分析了各参数对系统动态特性的影响,根据非线性规划最优化方法优化滑行平面参数。动态仿真表明,所提出方法在理论上是正确的,据此所设计的参数能使系统的动态响应达到最优,所设计的控制器具有很好的鲁棒性。
A new technique for designing an optimal variable structure AGC of multiatea power systems is presented . The individual sliding surface shosen is dependent only upon the state variable of the corresponding subsystem. The controller employs a new type of structuture. The infludnce of every parameter on system performance is analysed and ex amined in detail. An optimal designing technique based on nonlinear programming theory is used to optimize the parameters of slidingsurfaces. The results of simulation show that the method can optimize the system dynamic performance and the controllers possess high property of robustness.
