Research On Construction And Evaluation Of Operational And Maintenance Cloud Platform For Photovoltaic Power Station Based On Big Data

Along With the promulgation of relevant policies such as bidding for grid access and price reduction in photovoltaic industry,photovoltaic power plant is on the stage of high-quality development,and cost reduction and efficiency enhancement become a hot topic of industry concern.After the completion of the photovoltaic power plant,its 25-year operation and maintenance period becomes the main source of efficiency improvement and income.The traditional photovoltaic power station operation and maintenance system is mainly based on statistical analysis,and adopts the"smoke,type" multi-land and multi-level deployment mode,which not only wastes hardware and software resources,but also is difficult to expand,and the efficiency is extremely low,which cannot meet the user's urgent cost reduction and effective demand.In recent years,with the rapid development of emerging technologies such as cloud computing,big data,Internet of Things and mobile Internet,and its mature applications in medical and social fields,it is convenient and efficient.Therefore,cloud computing and big data core technologies and concepts are used in photovoltaic power station operation and maintenance,building an PV power plant operation and maintenance cloud platform that is intensive management,flexible storage,efficient and few or no one on duty 5has become an objective trend and inevitable choice for the development of the industry.Based on big data and cloud computing technology,first,this thesis expounds the key technology and practical application of big data and cloud computing,discusses the low cost and easy expansion advantages of photovoltaic operation and maintenance cloud platform and the improvement of operation and maintenance efficiency brought by the effective integration of photovoltaic large data and photovoltaic operation and maintenance management,the feasibility of constructing a photovoltaic power plant operation and maintenance cloud platform based on big data is proposed.Second,this paper discusses the current status of PV power plant operation and maintenance.For example,most of the power station operation and maintenance rely on personnel duty and equipment inspection.The operation and maintenance of the power station is limited by the professional ability and operation level of the operation and maintenance personnel.The idle time of the device caused by the long inspection time is long;some hidden devices are faulty,and the operation and maintenance personnel cannot know in advance and cause the accident to increase further.It deeply analyses the user's urgent need for cost?effective,intelligent operation and maintenance of photovoltaic operation and maintenance,and discusses the necessity of building a cloud platform for photovoltaic operation and maintenance based on large data.Third,it discusses the source,specific content and data types of PV big data from the perspective of the whole PV industry,and discusses the application of PV big data in fault alarm,power generation forecast,benchmark analysis and visual analysis of PV operation and maintenance.And analyzes the system business object,business scope,business process,data flow and performance indicators,and proposes the overall goal of system construction.Then,based on the demand analysis results of the photovoltaic power plant operation and maintenance cloud platform,the system architecture,business architecture,The network architecture,data acquisition and transmission architecture and security architecture,it discusses the core functions of the PV operation and maintenance cloud platform based on big data.Finally,it constructs a photovoltaic power plant operation and maintenance cloud platform based on big data,and evaluates the system from an economic point of view in an actual ease.At the same time,the analytic hierarchy process i5 used to evaluate the effect.After the study of this thesis,it has achieved the real application of big data in photovoltaic industry.Through the deployment and application of the system in many places in Gansu Province,the advantages of photovoltaic operation and maintenance cloud in reducing the cost and resources of operation and maintenance software and hardware has been verified,and the effects of intelligent alarm based on large data in improving operation and maintenance efficiency and optimizing operation and management capability of photovoltaic power plants has been demonstrated.
