摘要
根据双馈异步轴带发电机的运行特点,设计了网侧三相电压型变流器。在分析了变流器数学模型的基础上,采用解耦控制和双闭环矢量控制。在PI参数试探初值的基础上,通过仿真分析进一步调整了PI参数,试验了PI各参数变化对变流器动态性能的影响以及负载变化时,变流器的抗扰动能力,总结出一套可行的双闭环PI参数调整经验。
A supply-side voltage source rectifier （VSR） is designed according to the operating characteristics of the doubly-fed shaft generator system. The mathematic model of the VSR is analyzed and the decoupled-control, the dual-closed-loop vector-control is adopted. The PI parameters are further adjusted through the simulation analysis after getting the initial value of the PI parameters. The effect of the PI parameters on the system’s dynamic performance and the change of RL is illustrated and a simple method of PI parameters tuning is summarized.
