摘要
为消除电力系统区域间的低频振荡,设计了一种新的模型参考自适应控制器。自适应PI控制器的前馈和反馈增益矩阵可实时修正,为克服振荡提供更好的阻尼。文中专门讨论了控制量突变过程中,系统产生的冲击现象及其解决办法。单机-无穷大母线系统的仿真结果表明控制器有效。
A novel model reference adaptive controller is designed to eliminate the interarea low freguency oscillation in power systems. The adaptive proportional-integral controllers whose feedforward and feedback gains can be modified in real-time offering better damping effects against system oscillation. It is shown in this paper that bursting phenomena can indeed occar, and be eliminated by nonlinear block. Results from the simulation of a infinite bus system with a single unit show that the proposed controller is effective.
