【摘要】:在我国,风力发电在电力系统中的比重在逐渐增大,风能作为一种清洁能源,对改变现有的能源结构、促进国民经济和社会发展具有十分重要的意义。现如今风电生产面临诸多问题,其中包括风机类型繁多,风电场环境恶劣,运行人员技术水平不高,现有监控系统功能单一等。目前现代风电企业生产管理要求不同的风机、升压站都可以拥有统一的监控管理平台,实现风场远程集中监控、无人值守的目标要求。风电企业在向着集约化发展的同时要求监控系统可以提供丰富的报表种类、直观的图形化数据分析,为进一步实现风机故障早期预警系统提供数据和技术基础。为满足现场生产需求、推动技术进步,本文提出建立一个集中的统一监控中心,完成实时数据的采集与远程集中控制功能。首先,以风力发电远程集中监控系统的需求分析为基础,提出了建立远程集中监控系统的架构需求,最终采用C/S架构的B/S架构来进行Web发布系统的整体结构设计;同时利用Silverlight在交互网络程序开发方面的优势,结合风力发电系统的需求,开发出了丰富的应用程序,提升了用户体验;针对风场风机厂家不同造成的重复开发、程序不兼容及生产数据分散问题,监控系统采用Modbus和OPC的数据访问服务器进行开发研究,同时采用基于云平台大数据的集控技术来保证信息系统稳定、高效、可靠地运行。接着,根据之前提出的系统需求和采用的关键技术,设计了系统的整体架构并给出了系统的拓扑结构分析。完成了系统维护管理功能、数据采集处理功能、远程监视和控制功能的具体设计。最后,本文介绍了远程集中监控系统的具体功能实现,包括系统主界面、系统设置选项、风机状态监测、生产报表及远程控制功能的具体详述。其中详细介绍了风机状态监测功能,包括单台风机的状态监测、风机故障告警功能实现及风机内部具体部件的三维立体展示及监控功能。文末介绍了系统的一些高级扩展应用,例如针对该系统在移动终端的应用开发。
[Abstract]:In China, the proportion of wind power generation in the power system is gradually increasing. As a clean energy, wind energy is of great significance to change the existing energy structure and promote the development of national economy and society. Nowadays, wind power production is facing many problems, including the variety of fan types, the bad environment of wind farm, the low technical level of operators, the single function of existing monitoring system and so on. At present, modern wind power enterprises have different production management requirements of fans, booster stations can have a unified monitoring and management platform to achieve the wind field remote centralized monitoring, unattended target requirements. Wind power enterprises in the direction of intensive development at the same time the monitoring system can provide a variety of reports intuitive graphical data analysis for the further implementation of fan fault early warning system to provide data and technical basis. In order to meet the demand of field production and promote the progress of technology, this paper puts forward the establishment of a centralized unified monitoring center to complete the functions of real-time data acquisition and remote centralized control. Firstly, based on the requirement analysis of the remote centralized monitoring system for wind power generation, the architecture requirement of the remote centralized monitoring system is put forward. Finally, the C / S architecture of B / S architecture is adopted to design the whole structure of the Web release system. At the same time, using the advantage of Silverlight in interactive network program development, combined with the demand of wind power system, developed a rich application program, improved the user experience, aiming at the repeated development caused by different wind field fan manufacturers, The monitoring system is developed with Modbus and OPC data access server, and the centralized control technology based on the cloud platform big data is used to ensure the stable, efficient and reliable operation of the information system. Then, according to the system requirements and key technologies proposed before, the overall architecture of the system is designed and the topological structure of the system is analyzed. The system maintenance and management function, data acquisition and processing function, remote monitoring and control function are designed. Finally, this paper introduces the implementation of the remote centralized monitoring system, including the system main interface, system setting options, fan status monitoring, production reports and remote control function in detail. The condition monitoring function of fan is introduced in detail, including the condition monitoring of single typhoon machine, the realization of fan fault warning function, and the three-dimensional display and monitoring function of the specific parts inside the fan. At the end of the paper, some advanced extended applications of the system are introduced, such as the application development of the system in mobile terminal.
