Power Quality Of Grid-connected High Density Photovoltaic And Solution

In the process of photovoltaic power generation and network running and the network node voltage and network capacity due to fluctuations in the size, and because of the instability of the output power of photovoltaic systems, photovoltaic systems network voltage will appear, the current waveform distortion, thus affecting the power quality of the grid. This project aims to analyze Changxing County photovoltaic systems and network processes can occur in a variety of power quality problems.The roof photovoltaic power generation for the waveguide dream Food Co. Ltd. and Zhenlong power company installed the project as an example, several performance related hardware for photovoltaic system produced by analyzing the plant, research on all kinds of device characteristics such as photovoltaic cells U-I, P-I characteristics, the maximum power tracking method, the main control strategy of grid connected inverter and so on, finally through the simulation modeling of the synchronization process of power quality problems are verified.
