The Research And Implementation Of Centralized Monitoring System For Wind Farms Based On Hadoop Platform

With the increase of new energy sources capacity,mainly wind power and photovoltaic,how to achieve high efficient of new energy companies,is particularly important for us.The wind farms in the northern part of Shandong(Dongying and Binzhou)are mostly located on the beach and salt fields.The capacity is large and the wind resource is superior.However,the distribution of wind farms is relatively scattered.The operation and maintenance management is extremely inconvenient.The living environment is bad and the loss of professional talents is serious.As of the end of June 2018,the installed capacity of wind power in northern Shandong was 1,628,800 kilowatts,accounting for 15.08%of the total installed capacity of wind power in Shandong Power Grid.As the scale of wind power investment in this region continues to expand,this number will continue to rise.How to achieve the centralized monitoring of regional wind farms in this region,to achieve the goal of "centralized monitoring,few people on duty,no one on duty",is very important for improving the quality of production of our company.This paper analyzes the current construction status of wind farm centralized control system,and refers to the relevant regulations of A company in Shandong province.The centralized monitoring system of wind farm based on Hadoop large data platform is firstly realized.At the same time,in response to the requirements of localization of the national grid,the system is based on the localization operation system.Firstly,the status and problems of wind power centralized monitoring system at home and abroad are analyzed,and the significance of developing centralized monitoring system based on large data platform is obtained.Secondly,take Company A as the research object.Based on the requirement investigation of the centralized control center and the wind farms of the company,a detailed requirement specification for the construction of the centralized control center system is formed.The system functions are divided into six functional modules:data acquisition,production equipment monitoring,equipment remote control,report forms and statistical analysis,index analysis,intelligent alarm.Each functional module is analyzed in detail and illustrated with use case diagram.Thirdly,the implementation technology of centralized control center system is analyzed,and the drawbacks of centralized control center system based on relational database and sequence database are found out,and the design idea of wind farm centralized control system based on Hadoop large data is determined.Finally,the implementation process of the system is described in detail.According to the function module,each function module selects the representative function,and introduces the function realization of the centralized control system.Finally,the implementation process of the system is described in detail.According to the function module,each function module selects the representative function,and introduces the function realization of the centralized control system.It effectively solves the problems of slow data storage and lack of large data analysis function in traditional centralized control center system.The centralized management of six wind farms,including Xinhu,Hekou,Lijin,Chengkou,Zhanhua and Guangrao,has been realized,and the operational benefits of each wind farm have been improved.Large data analysis function of the system can quickly analyze a large number of wind farm data,find the causes of power loss of wind farm,assist us to detect defects and improve fault handling efficiency.Our system also give the large data analysis report forms,in order to further improve the management of wind farms,enhance the fan power generation.
