基于Quanser的并网逆变器半实物系统设计

以加拿大Quanser公司的实时数据采集卡和实时系统为核心,采用基于模型的方法在Matlab中设计了并网模型,通过搭建外围硬件电路,形成了并网逆变器半实物仿真系统。系统采用Boost升压方法实现DC-DC电路,采用单相全桥逆变电路结构实现DC-AC,通过数据采集卡输出PWM和SPWM波,用锁相环进行系统的同频、同相控制,最终实现逆变器并网输出。实验结果表明该方案可行,控制灵活高效,为并网控制算法研究提供了新的研发平台。

Semi-physical System Design of Grid-connected Inverter Based on Quanser

This paper takes Canada's Quanser data acquisition card as the core,by building peripheral hardware circuits,combined with the grid-connected simulation model built in Matlab,forming a grid-connected inverter semi-physical system.This paper designs DC-DC using Boost boost and DC-AC adopts single-phase full-bridge inverter circuit structure,and realizes PWM and SPWM waves by building simulation model and Quanser acquisition card modulus function,and uses the phase-locked loop to control the same frequency and phase in the system.The control is flexible and simple.
