【Abstract】 In order to solve the defects of coal energy consumption and harmful environment in laboratory experiments, an experimental platform for digital physical hybrid simulation of photovoltaic power generation was designed and built. The data signal was converted and processed by the control machine and open converter, the signal was tracked and monitored in real time by the microsecond real-time simulator, and the ideal waveform was finally obtained. At the same time, a hybrid simulation experiment test was carried out to integrate the photovoltaic power station into the 380 V power grid under different optical radiation intensity when the ambient temperature was unchanged. The results show that the waveform of the hybrid simulation results coincide with the waveform of the full digital photovoltaic power station, which can achieve the ideal experimental goal. The experiment platform fits seamlessly with the photovoltaic power station, which verifies the effectiveness and accuracy of the platform. The experimental platform can be used for current and voltage testing and power calculation of a series of grid-connected tests of photovoltaic power stations, hence, it has wide applicability and strong expansion.更多还原
