Research And Design On Remote Monitoring Platform For Photovoltaic Application System

With the constant development of solar energy generation technology,photovoltaic application system is provided with increasingly more progress advantages.Based on such a system,nearby power generation,nearby conversion and nearby application can be fulfilled so as to eliminate the power transmission process in addition to minor losses and high efficiency.Moreover,it can be applied into promoted in areas with abundant sunshine.However,the photovoltaic application system is distributed dispersedly and independent mutually,which brings difficulties to the corresponding management and maintenance.How to acquire photovoltaic application system operation data becomes one of the key issues to further popularize the photovoltaic application system.In this paper,a remote monitor technique is studied specific to the photovoltaic application system and the following tasks have been completed principally.1.Status quo of foreign and domestic researches on the monitoring technology of photovoltaic application system is overviewed.Through studying literatures relevant with such a technology of this system in recent years,accomplishments and development tendencies of the photovoltaic application system monitoring technology for the past few years are summarized.2.Photovoltaic application system design is achieved.Through studying the common inverter structure of a photovoltaic application system,an appropriate circuit topology is selected to design a photovoltaic application system that is provided with an identical structure by an output way of small power and low voltage;then,this system is used to perform researches on the corresponding monitor technique.3.A remote monitoring platform is designed for the photovoltaic application system.Data collection in the wireless Ad Hoc networks and multiple data transmission technologies are employed combined with a server to design a remote monitoring platform for the photovoltaic application system with real-time monitoring function.Finally,functional verification is accomplished in the laboratory for such a remote monitoring platform of this system.A method of cell-divided verifying followed by joint commissioning is utilized to test functions of the remote monitoring platform direct at such a photovoltaic application system in the lab.Through verification,the entire system is able to fulfill expected requirements efficiently,such as data collections,group-net communications and real-time data monitoring.
