Research On Monitoring System Of Photovoltaic Inverter Based Embedded

The shortness of energy is getting ever more acute, which gives great opptunity to the development of new energy, such as wind energy and solar energy. As an important application of solar energy, photovoltaic power generation draws more attention. And as one of the most important parts of photovoltaic power generation system, the monitoring technology of photovoltaic inverter is meaningful to photovoltaic inverter and the whole system.The paper designs a monitoring system of photovoltaic inverter based on embedded system to monitor several photovoltaic inverters. It acquires data and intercharge data through Ethernet. The master station analyzes, manages, prints, displays and stores data. It also plots and sets parameters.The paper does research on the principle and architecture of photovoltaic inverter, analyzes the fieldbus and Ethernet. It starts with the aspects of the hardware and software design of data collection, data communication, application design, designs hardware and diver of data collection of the system. Then it transplants Qt/Embedded on Linux, and designs application program with UDP and MySQL. The last is the verification of whole system by testing.
