基于粒子群的水力发电力组综合控制研究

Study on the Integrated Control System for Medium and Small Hydro-power Generator Based on PSO

针对中小型水力发电机组的优化控制问题,提出一种转速和发电励磁的综合控制方法。该方法有效地解决了单一励磁或者调速控制方法存在的控制误差大、过渡过程时间长,控制精度低的问题。还提出了基于粒子群(PSO)的PID控制参数优化设计方法,解决了系统参数的优化问题。通过比较此方法和传统PID的控制,仿真结果表明了该方法的有效性。

To solve the optimal control problems of small and medium - sized hydropower units, this paper proposes a method of integrated control of power excitation and speed. This method can effectively reduce the problems existing in a single excitation or speed control , shorten the transition process time, and improve the control precision. The PID control parameters optimization design method which is based on Particle Swarm Optimization（PS0） is also proposed in this paper. Finally, the simulation results of this method are compared with those of the traditional PID control, which shows the effectiveness of this method.
