摘要
远程数据中心系统作为风电场远程监控系统的重要组成部分,其性能的优劣直接关系着风电场远程监控系统的整体性能。具有通用性和重用性的远程数据中心系统不仅能够提高远程监控系统在风电场应用的效率,同时也有利于满足风力发电场迅速发展的需求。随着互联网的迅猛发展,建立一个风机制造商自己的数据远程监控中心,把各风场各厂家的运行参数集中起来比较分析,已经成为当前和未来的研究热点和发展趋势。
本文的研究实现了通过电信的无线传输设备收集风电场数据,各个服务中心使用通用的IE浏览器可以读取相关数据的东汽远程数据中心系统。主要分为三层体系结构:表示层、业务逻辑层和数据层。以参考当前比较流行的数据库技术开发经验的基础上,结合Internet技术、3G无线网络,以获取风力发电场风机组运行数据为背景,设计出一种远程数据中心系统。该系统能实时采集东汽分布在全国各地的风场内风机的各种数据,能够对历史数据进行分析比较,能根据相关数据进行在线监测、故障分析,从而及时准确地了解各风场风机的运行、故障情况,对后续风机的研发、设计和改进提供各种有利依据,为现场服务提供技术支持等。
Remote data center system is an important part of the remote monitoring system for wind power, the merits of their performance is directly related to the overall performance of the remote monitoring system for wind power. With the versatility and reusability,the Remote data center system can not only improve the efficiency of applications of the remote monitoring system in wind farms, but also conducive to meet the needs of the rapid development of wind farms. With the rapid development of the Internet, the manufacturers of the wind field building a remote monitoring data center and operating parameters together to analyse comparatively, have become the research focus and the future development trends.
This paper implements the DEC remote data center systems from which the various service centers in the IE browser using the common wind data collected by Telecom's wireless transmission equipment. The system mainly divided into three-tier architecture: Presentation layer, business logic layer and data layer. Refer to the current popular development experience of the basis technology on database, with the Internet and 3G wireless network technology, to obtain operating datas of wind plants, we designed the remote data center systems . To grasp the operating and fault conditions of the wind plants timely and accurately, to provide all kinds of favorable basis for the following research, design and improvement, technical supporting for the on-site service, the system can collect various real-time data from the DEC wind plants distributing throughout the country, analysis and compare historical data, according to data monitor on-line and analysis of failure.
