Prospect of Photovoltaic System Safety Monitoring and Fault Diagnosis Technology Based on PV Cloud Data Platform

With the rapid development of solar energy, effective safety monitoring and fault diagnosis technologies for photovoltaic generation system are urgently needed. According to the collected local station data, traditional technologies still have some deficiencies in fault diagnosis and fault location. In this paper, the safety monitoring and fault diagnosis technology based on the photovoltaic cloud data platform is put forward, which will increase the safety, stability and economic operation level of photovoltaic power plants. The advantages of the proposed technologies are prospected as well. The photovoltaic cloud data based method will be an important development trend for safety monitoring and fault diagnosis of photovoltaic power plants.
