Due to some difficulties such as monitoring the information of power station, lack of effective operation and maintenance approaches for devices, large power energy loss, lower operation and maintenance efficiency and cost sensitivity in the access of distributed poverty alleviation photovoltaic to weak distribution network disorderly, actual situation of poverty alleviation photovoltaic construction was taken into consideration. And the demand for intelligent operation and maintenance of distributed poverty alleviation photovoltaic were fully studied. This paper proposes the design scheme of intelligent operation and maintenance service system for distributed poverty alleviation photovoltaic, and explains system composition, function planning, communication network architecture, development of monitoring terminal and so on. This system consists of formation equipment,main station layer equipment and network layer and so on. Combined with the application of the system in a distributed poverty alleviation photovoltaic project in a certain city in China, the benefits of power generation are quantified, and the application effect evaluation of the system is given. It is verified by engineering that the system can improve the benefits of power generation, reduce the cost of operation and maintenance and has good promotion and application value.
