Experimental Design Of Photovoltaic Power Generation System

In the new energy power generation technologies, photovoltaic power generation for its unique advantage to win a broad market. With the popularization and application of photovoltaic technology, grid-connected PV systems are being more and more attention. Photovoltaic grid-connected converter as a core part of PV system, its performance advantages and disadvantages related to efficiency and operation stability of the photovoltaic power generation system.This paper introduces the experimental system of photovoltaic power generation photovoltaic converter performance test, focus on the principles and experimental methods of MPPT(Maximum Power Point Tracking), anti-islanding, LVRT(low voltage ride through) and a number of other important experiments in the photovoltaic power generation system. Designed to meet the requirements of these experiments and the experimental system of photovoltaic power generation was experimentally verified. Experiments show that this design of photovoltaic power generation systems can perform series of experiments with photovoltaic cell panels, photovoltaic converter and power-related experiments, experimental studies can be used to optimize system performance due to the result, and to test performance of photovoltaic grid-connected converter.
