The Design And Implementation Of Remote Data Acquisition And Monitoring System Of Intelligent Photovoltaic Power Station

This thesis introduces the principle of solar photovoltaic power generation and theconstitute of photovoltaic power station, and analysis the Design and implementation ofremote data acquisition and monitoring system of intelligent photovoltaic power station, dothe developing and testing of the software system.A complete photovoltaic power station includes solar panels(PV module), inverter,data collector(gateway) and the monitoring system. Solar panels convert the light energy toelectrical energy, inverter is for DC to AC, data collector can collect multiple inverter dataat the same time, then send the data to the monitoring system via Ethernet.The monitoring system is an important part of the whole photovoltaic system,including two parts of the data receiver and the web user interface. The data receiverreceives the data from gateway all over the world, do the data analysing and storing. Theweb user interface display the data in the database in a form of chart, report and so on.Monitoring system can detect the equipment failure, early warning information of thepower station, and through emails, messages to inform the user or the plant manager,which makes solar power plant a really intelligent power plant system with nobody on dutyand less maintenance.The software uses Microsoft Visual Studio2012and.NET Framework4.5as thedevelopment platform, the database server using MySQL. The monitoring system isdesigned by B/S mode——browser and server interaction structure, using MVC three-tiermodel layer, the system’s model layer, view layer and control layer separation, in order toachieve decoupling purposes, to facilitate the development and maintenance of the system. The system mainly includes the real-time monitoring, the layout interface, reportinterface, alarm interface, the user can probably understand the status of their own plantwhenever and wherever through logining their own plant.
