Large Ground Photovoltaic Power Station Power System Monitoring Research

The world is already the globalization society, the environmental pollution question is us all should pay attention to. Save the environment has become an important theme of our era, solar energy, such as renewable energy need to actively take full use, so we need to intensify efforts to promote the development of photovoltaic industry. Photovoltaic power plant located in larger area of wasteland or roof, the staff usually cannot easily to the scene to see, the normal operation of equipment and not and the surrounding environment changes affect output from the power stations, so monitoring is very important for the operation of photovoltaic power station. Monitoring system can help staff to view the scene, collect equipment running data, and analyze and handle the power station in real time.First, through access to relevant literature, understand the research status of photovoltaic power plants and power station monitoring system. And in the monitoring field station, information and data of the monitoring station were collected, according to the operation characteristics of PV power plant in the power generation process, the main influence factors of the PV array is analyzed and summarized.Second, the main factor of the impact of the monitoring of the main factors of the design, different sensors were selected. The main factors affecting the power generation of solar radiation, temperature characteristics, to track the maximum power output, inverter, battery, wind speed, wind direction and other, through the hardware and software design, the system can data on the impact factors of generating capacity of automatic monitoring, and the ability to view real-time running state.Third, to monitoring system of telecontrol system to do the research. In the monitoring belongs to the range of macroeconomic regulation and control, regional, and controllability. The telecontrol system improves the system stability and execution ability.
