The integration of large-scale photovoltaic power plants into the power system has caused voltage control problems, and this article conducts research on reactive power control optimization. Through the comparative analysis and research method of field test and simulation test data, the model of photovoltaic inverter and Static Var Generator (SVG) is established, and the equivalent modeling of photovoltaic power station is carried out. The reactive power control optimization strategy of photovoltaic power station is proposed. Taking an actual photovoltaic power station as the research object, the effectiveness of the proposed method is verified against the field voltage control problem.
With the increasing emphasis on the application of renewable energy in the world, photovoltaic power generation has ushered in a rapid development stage. Photovoltaic power generation equipment is an essential part of photovoltaic power generation, and its reliability plays a positive role in the development of renewable energy. This paper makes statistics on the fault rate of the power generation equipment in a practical photovoltaic power station, including photovoltaic inverter, combiner box, photovoltaic modules, etc., sorts out the types of faults, analyzes the key factors that affect the fault of the equipment, and puts forward future research directions.
