Design And Implementation Of Distributed Photovoltaic Power Generation Monitoring System Based On Hadoop

In 2013,the National Energy Administration adjusted its strategy on photovoltaic development to focus on distributed photovoltaic power station,which is expected to surpass large-scale ground power stations by 2020,accounting for 56% of the total.Compared with the traditional ground power station,distributed photovoltaic power generation has the characteristics of wide application range,small site scale,scattered site,and cluster effect.With the rapid growth of distributed photovoltaic power station,the problems of immaturity in supporting monitoring,low power generation efficiency of the power station,and fire led by the hidden danger of equipment become more and more prominent.Photovoltaic enterprises need a new monitoring management mode to solve these problems.The main research contents of this paper are as follows:1.In the research,we use Hadoop distributed data storage technology to store time-point data of mass devices in Hive,and use Hive QL to ETL historical data and build historical data warehouse,which solves the bottleneck problem of traditional relational database storage and analysis under large data volume,and provides powerful data support for industry data mining and value-added service.2.Data table related to the asset management of the power plant is designed,the centralized management and visual display of the photovoltaic power plant is realized.Through the power station information display page,managers can quickly view the comprehensive information,and can accurately locate the problem and shorten the processing time when dealing with the fault.3.Patrol rules are designed to realize the overall monitoring and automatic patrol of photovoltaic equipment.The automatic patrol inspection for abnormal alarm events reduces the daily patrol work of operation and maintenance personnel,improves the rate of equipment failure detection,and enables operation and maintenance personnel to deal with complex problems more attentively.The monitoring system is developed based on the main SSM(Spring,Spring MVC,My Batis)framework,which realizes six functional modules: real-time monitoring,patrol inspection management,alarm management,report analysis,asset management and system management.Finally,the function test and performance test are carried out to ensure the effectiveness of the system..
