摘要
光伏系统最大功率跟踪(MPPT)控制器是验证各种MPPT控制算法的关键手段,目前控制器的开发存在开发周期长、代码需要人工编写等缺点。RT-LAB实时仿真平台突出的实时性能使其在目前的试验研究和工程设计中的使用越来越广,所以有必要对其软硬件结构及其实时性能进行研究。为此,首次全面系统的介绍分布式实时仿真系统RT-LAB的硬件结构,软件结构和仿真实现流程,结合RT-LAB半实物仿真技术和光伏MPPT的特点,进行了半实物仿真试验。试验中的MPPT控制策略通过结合Simulink软件包模型搭建实现,控制器之外的主电路采用实物电路,RT-LAB的在线调参等功能可以方便的优化控制器参数。对RT-LAB在电力电子半实物仿真中的两个特殊工具ATMISE和RT-Events的特性进行了详细说明,同时阐述了RT-LAB的软件建模规范。试验表明运用RT-LAB进行光伏控制器的开发可以解决目前控制器开发中的诸多问题。RT-LAB在光伏系统上的应用为其在微网、智能电网等实时性要求较高的系统上的应用提供参考。
The maximum power point tracking（MPPT） controller in the Photovoltaic system is the key mean to verify all kinds of MPPT control algorithms.But the development of actual controller has the defects of needing long periods,artificial code writing and so on.RT-LAB real-time simulation platform is an advanced model-based engineering design and test application platform.The outstanding real-time performance in the current experimental study and engineering design made it used more and more widely.Therefore,it is necessary to introduce its hardware and software structure and real-time performance in detail.This paper gare a comprehensive and systematic introduction to hardware architecture,software architecture and simulation process of RT-LAB.It also presented a semi-physical simulation experiment of photovoltaic system MPPT using the features of Photovoltaic MPPT and semi-physical Real-Time simulation technology.The MPPT control strategy is achieved by establishing model using simulink package.Other parts of the main circuit were physical circuit except controller.The parameter adjustment functions on line of RT-LAB can easily optimize controller parameters.Two special tools ARTEMIS and RT-Events used in power electronics were described in detail.The RT-LAB software modeling standard was also illustrated.The testing results showed that the usage of RT-LAB for the development of photovoltaic controller can resolve many problems in the current controller development.The application of RT-LAB in photovoltaic systems provides a reference for the microgrid,smartgrid and other real-time systems.
