| 摘 要： | 基于非线性预测控制理论,设计出具有闭型解析解控制律的汽轮发电机汽门开度分散非线性预测控制器。该控制器并不要求进行在线优化计算,从而避免了繁重的计算负担。控制器的输入为当地可测量信号且与网络参数无关,从而实现了分散控制。通过在6机22母线系统的仿真结果表明,该控制器能提高电力系统的暂态稳定性和动态性能。

| Abstract: | A novel decentralized nonlinear controller with closed-form analytic solution control law for steam valve of turbine-generators in multi-machine power systems is presented, on basis of the nonlinear predictive control theory. The highlight of this method is that the controller does not require on-line optimization and the huge calculation burden can be avoided. The input signals to the proposed controller are all local measurements and independent to the system parameters. The simulation results in a 6-machine 22-bus power system demonstrate that the controller can greatly improve transient stability and dynamic performance of power systems. |
