The fault of insulation leakage of distributed photovoltaic power station is always the technical difficulty of photovoltaic power station.Especially in every link from the photovoltaic cell array to the grid-connected inverter, the wiring is complicated and the environment chervo jacke herren is bad.In view of the disadvantages of traditional monitoring technology, a distributed leakage monitoring system based on power line communication is proposed.The system combines the power line communication technology with the 1073spx sensor technology.
The design and optimization of the hardware and software of the acquisition node and the central monitoring terminal are completed.The data collection and transmission of collecting point leakage current are realized.The system is tested with different temperature conditions.Through experimental verification, the reliability of the system is above 97%, which can effectively monitor the leakage of distributed photovoltaic power station.
