Design And Implementation Of Remote Monitoring System For The Integrated Management Platform Of Wind Farm

Mengneng Electric Power co., LTD has built wind power plants such asWula, Xini River and Bayan in Ulanhot, which are far away from the centerof the city geographically. There are wind turbine generator monitoring systems, booster station integrated automation systems, wind power plant image monitoring systems, booster station device alarm systems and wind power prediction systems built in each wind power plant. These systems are scattered in the booster station of each wind power plant, belonging to different vendors, for their respective array under independent operation, which do not only increase the cost and resources of system, but also make it difficult to realize datasharing among various systems and overall consideration. This topic will establish a centralized control center in Mengneng Ulanhot District, bringing remote control, data administration and instructions dispatching of each wind power plant into a unified system platform, to exert the overall superiority of centralized management in wind power plants by optimizing operation.This topic is carried out around the design and implementation of centralized control center management platform, mainly studying the architecture design, function design, software development, hardware integration, etc. The architecture design establishes hierarchical architecture based on the basic structureof production automation and information management system, forming three-layer Web system of client, interlayer and server. The function design includes the comprehensive monitoring, power prediction, energy management, fault alarm and intelligent auxiliary of the wind power plant, grasping the equipmentoperation of wind farms and environmental monitoring data in time throughthe centralized control center to analyze the data and send control messages to the wind power plant through the network, realizing the remote control andmaintenance of systems. Software development and application object-orientedlanguage and large relational database collect, process and store data, conduc ting modularization development according to the guidance of software engineering theory. Designing data interface and communication interface provides real-time data monitoring, inquiring and counting and other information servicesfor clients. Hardware integration is constituted by server, network equipment,data acquisition and video monitoring equipment, providing high-performanceand high-availability data operation and data storage resources for the normaloperation of the software system.The design of centralized control center remote monitoring platform doesn’t only achieve the wind power management mode of centralized control, noone on duty on site, less men on duty and regional maintenance, but also reduces the operation and maintenance costs of wind power plants, what’s more,it can send the wind power prediction data and other information of wind power plants in different districts in time to centralized control center for monitoring and contrasting, which improves the reasonable arrangement of plannedmaintenance work in wind power plants. In addition, the remote monitoringsystem can comprehensively monitor the operating condition of each draught fan and equipment in station and according to the wind power prediction accurately estimate the load change trend to provide reliable basis for maintenancecondition. It also accepts the dispatching instructions and controls power output of regional wind power plants rapidly as well as monitors the regional load distribution, achieving the goal of controllable wind power operation and providing technical support for wind power clustering development as well as establishing a solid foundation for rapidly improving the domestic wind powerdigital process and adjustment of industrial structure.
