用于光伏系统MPPT充电控制器开发的软件在环、硬件在环和功率硬件在环实验平台

Abstract Hardware-In-the-Loop (HIL) and Power-Hardware-In-the-Loop (PHIL) simulations enable the combination of software and hardware to test and optimize devices or technical systems under conditions as close to real life as possible. This paper presents the real-time simulation techniques consisting of Software-In-the-Loop (SIL), HIL and PHIL models of the Maximum-Power-Point-Tracking (MPPT) charge controller for photovoltaic system. The SIL, HIL, PHIL simulation techniques play a role as a successive stage of the product development process of the MPPT controllers. All models are built on Matlab platform software and run on the OPAL-RT real-time simulator. The proposed SIL model consisting of Photovoltaic system (PV), buck converter, MPPT controller and battery is executed on the real-time simulator considering the computation time of the entire system. Meanwhile, the HIL model allows to verify the MPPT controller which is built on DSP F28379D microcontroller, and the PHIL model allows to verify both buck converter circuit and real MPPT controller. The results of the SIL model show that the computation time of the model can be adjusted so that the SIL system meets the real-time simulation requirements, while the HIL and PHIL models are capable of verifying the real equipment parts of the system. Therefore, the proposed SIL, HIL and PHIL models of the MPPT charge controller for photovoltaic system are a technique worth considering in the development of real MPPT controller.
