Research And Implementation Of Key Technologies Of Wind Power Monitoring System Based On B/S Architecture

China's wind power installed capacity ranks first in the world.How to ensure longterm,stable,safe and full load operation of wind turbines has become the focus of the industry.Wind power monitoring system monitors the running state of wind turbine in real time.It plays an irreplaceable role in reducing the operation and maintenance cost of wind farms and improving the management level.The wind power monitoring system based on the B/S framework has become an inevitable trend of development.In view of the poor real-time data display of wind power monitoring system under the B/S framework and the lack of control over the operation rights of wind turbines at all levels,the main research work is as follows:In view of the low efficiency of data transmission in B/S architecture,this paper designs a access separation scheme based on real-time data,which reduces the number of requests for most of the non real-time data to 1 times,thus greatly improving the efficiency of data transmission.In view of the poor real-time data display,this paper designs a multi protocol combined real-time data transmission scheme including Websocket protocol,MQTT protocol and Profibus-DP protocol.It avoids this problem by using the combination of message subscription and publishing model and data push model,which greatly improves the B/S architecture.The real-time performance of the lower data displayIn view of the lack of control over the operation power of wind turbines by multilevel wind power monitoring systems,this paper proposes a wind power generation unit operating permission interlock control program,through the integrated request IP address,account permissions,location priority and other variables to control the operating authority of the wind turbine,basically eliminate the security threats caused by lack of privilege to control operation and maintenance personnel.The wind power monitoring system based on B/S architecture is designed and realized,including the single unit wind power monitoring system and the wind farm centralized monitoring system.The system has the characteristics of advanced technology,powerful function,beautiful interface and so on.
