摘要
分析了应用于纯交流母线型"风光柴"互补发电系统10kW风电并网逆变器。该并网逆变器具有独立运行和并网运行两种工作模式。通过引入卸载电路、Boost电路来扩大风电并网逆变器的输入电压范围、提高了逆变器的稳定性。利用DSP编程产生SPWM控制信号,电路结构得以简化。引入电压前馈控制,提高了逆变器并网模式下的暂态响应性能。通过对样机的实验观测,实现了设计要求。
A 10 kW wind power grid-connected inverter for alternate current bus wind-solar-diesel hybrid generation system is analyzed.This grid-connected inverter can be worked in two ways,stand-alone or grid-connected.The un- loaded circuit and Boost circuit are used to enlarge the input range and improve the stability of the grid-connected inverter.With the SPWM produced by DSP,the circuit is reduced.The feed forward control is used to improve the transient of the grid-connected inverter.According to the experimental results,the design requirements is realized.
