永磁同步风力发电机的双启发式动态规划控制

Control of Permanent Magnet Synchronous Generators Based on Dual Heuristic Programming

永磁同步风力发电机(PMSG)的功率控制一般基于线性控制理论,致使其动态性能难以完全满足风电场运行的需要。本文采用双启发式动态规划(DHP)对PMSG的输出功率进行控制。首先阐述PMSG的工作原理,然后搭建动态模型,编制了DHP算法的C程序,创建DHP控制模块以更换动态模型中的PI控制模块,最终接入到IEEE 10机39节点系统进行时域仿真并调节参数。仿真结果表明,应用DHP算法有效实现了PMSG的功率控制,获得了较为理想的动态性能。

Due to the fact that the power control of permanent magnet synchronous generators（PMSG）is usually based on linear control theory,its dynamic performances cannot fully satisfy the operation requirements of wind farms. In this paper,dual heuristic programming（DHP）is adopted to control the output power of PMSG. After the introduction of the working principle of PMSG,its dynamic model is established. The DHP algorithm is written using C programming language,and the DHP control blocks replace the PI control blocks in the dynamic model of PMSG,which is incorporated into the IEEE 10-generator 39-node system to perform time-domain simulation with adjusted parameters. Simulation results show that the output power of PMSG can be effectively controlled with DHP,and a desired dynamic performance can be obtained.
