The Design And Development Of Data Acquisition Monitoring System Based On The Wind Power Generation Technology Of The Multistage Cache

Wind power data acquisition monitoring system is all sorts of electric equipment in the process of the wind farm running and maintenance, control and automation gradually to be perfect and stable, is an automation advantages of the product of giving full play to the communication, data processing, data analysis, data storage, and professional performance index analysis. Especially in the realization of wind farms under the unattended goal, not only for the remote monitoring of individual wind turbines, but also integrate the entire wind power substation and wind equipment access and index of the establishment of a remote data center, etc.By providing the report of real-time data, data processing and graphic display, make management convenient and fast to do on the court state query and function of each unit. On this basis, the system according to the principle of flexibility and openness in special circumstances can adapt to various wind farm at the same time, also set aside for a variety of advanced features module interface.Wind power data acquisition monitoring system will set a variety of different control systems interconnection, make all kinds of information and resources to effectively coordinate as a whole. Has sufficient flexibility and extensibility, able to adapt to the changes in the environment inside and outside, at the same time considering wind forecasts, reliability,maintenance and emergency dispatch function modules such as embedded seamlessly.In recent years, our country has carried out a variety of wind power data acquisition monitoring systems, and the SCADA system is used more in monitoring and control systems,it is mainly for data acquisition and monitoring. In the process of research of this topic, we saw a lot of information about domestic case, with the corresponding areas and the corresponding technology in Germany, designed the SCADA system and the network technology with the combination of wind power system network architecture. SCADA system framework based on the single wind power monitoring automation system, combining with the Internet technology and database technology, data communication between multiple wind turbine information acquisition and monitoring, at the same time, as far as possible the consideration of wind turbines in the case of errors or other malfunction to remote diagnosis and so on, the implementation of wind power according to the data collection to implement the automation, a remote monitoring system.Explosive the designation of the multistage cache data processing system for SCADA system, using the data receiving module receives the request message application sends data storage, according to cache state of the queue in buffer queue; Data to proofread module file cache module the data stored in the storage request is inserted into the cache queue;Optimization module reads the data cache in the queue to requests for data storage to the optimized data storage requirements free threads in the calling thread pool, perform datastorage operations. This topic can better solve submitted to mass data storage request, the request data and the security of SCADA system problem.
