Solar PV Power Monitoring System Solution
Application
Most of the 380V distributed photovoltaics are rooftop photovoltaics of industrial and commercial enterprises, which are used spontaneously for self-use and the surplus power is put on the grid. Before distributed photovoltaics are connected to the distribution network, the metering points should be clearly defined. In addition to the property rights demarcation point, the metering point setting should also consider the distribution power outlet and the user's own power line. Each metering point should be equipped with a two-way electric energy metering device, and its equipment configuration and technical requirements must comply with the relevant provisions of DL/T 448, as well as relevant standards and regulatory requirements. The electric energy meter adopts a smart electric energy meter, and its technical performance should meet the relevant standards of the State Grid Corporation of China for smart electric energy meters. Distributed power metering devices used for settlement and assessment should be equipped with collection equipment and connected to the electricity consumption information collection system to realize remote automatic collection of electricity consumption information.
