More Information
Summary:The invention discloses a distributed photovoltaic grid-connected modularized power generation system embedded electricity stealing prevention device. The existing microprocessor-based electricity stealing prevention technology has defects of inconvenient use and poor reliability. The device of the invention comprises a DC module electricity stealing prevention calculation communication unit and an AC module electricity stealing prevention calculation communication unit, and design and mounting are carried out according to the corresponding distributed photovoltaic grid-connected modularized power generation system. After receiving any electricity stealing alarming signal from an RS485 communication interface, an alarming circuit of the DC module electricity stealing prevention calculation communication unit instantly carries out lamp indication and buzzer alarm. After an electricity stealing behavior is judged to happen or any one electricity stealing alarming signal from the RS485 communication interface is received, the AC module electricity stealing prevention calculation communication unit instantly carries out lamp indication and buzzer alarm. Whether the electricity stealing behavior happens to the distributed photovoltaic grid-connected modularized power generation system can be recognized, and when the electricity stealing behavior happens, the electricity stealing amount can be accurately metered, and alarming processing is carried out.
