When constructing a new generation mode, there are high requirements for the application of various equipments. Among them, the generator set belongs to special equipment, which needs to be managed in order to realize the scientific utilization of energy and the protection of surrounding environment. At present, China has gradually expanded the construction scale of related industries, and at the same time introduced more advanced technology, and carried out all-round control on the power generation mode. This paper analyzes and discusses the operation control technology of distributed photovoltaic power generation.展开更多
