【摘要】：风电数据采集监控系统是在风电场各种电气设备运行维护、控制和自动化过程中逐步完善和稳定的,是充分发挥通讯、数据处理、数据分析、数据存储和专业性能指标分析等自动化优势的产物。尤其在逐步实现风电场无人值守的目标下,不仅要针对单个风电机组的远程监控,还要整合整个风电场的变电站和测风设备接入以及远程数据中心的建立等多方面的指标。通过提供完善的实时数据报表,数据处理和图形显示,使管理人员方便、快捷的做到对场内各个机组的状态查询和功能控制。在此基础上,系统遵循适应性和开放性原则,在可以适应各个风电场特殊情况的同时,也为各种高级功能模块预留接口。风电数据采集监控系统将各种机组不同的控制系统进行有机的互联,使各种信息和资源有效地协调成一个整体。具备充分的灵活性和扩展性,能够及时适应内外环境的变化,同时考虑风能预测、可靠性维修和应急调度等功能模块的无缝嵌入。近些年来,我国开发了多种的风力发电数据采集监控系统,而这些监控系统中运用较多的则是SCADA系统,它主要是对数据采集和监控。在对本课题的研究过程中,就SCADA系统的运用翻阅了国内较多的风力发电案例,进而结合德国相应领域中所采取的相应的技术,设计了SCADA系统与网络技术相结合的风力发电网络化系统架构。SCADA系统框架以单独的风力发电监控自动化系统为基础,结合互联网技术以及数据库技术,实现多个风力发电机组之间通信数据信息采集和监控,同时,尽可能的考虑风力发电机在发生错误或者其他故障时能够进行的远程诊断等等,实现风力发电按数据采集监控系统的自动化、远程化实施。面向SCADA系统的爆发式数据多级缓存处理系统的设计,使用数据接收模块接收应用程序发送的数据存储请求报文,按缓存队列的状态放入缓存队列中;数据预读模块将文件缓存模块中存储的数据存储请求插入到缓存队列中;数据优化模块读取缓存队列中的数据存储请求,对数据存储请求优化后调用线程池中的空闲线程,执行数据存储操作。本课题能够较好地解决提交海量数据存储请求时,请求数据及SCADA系统的安全性问题。
[Abstract]:The wind power data acquisition and monitoring system is gradually perfect and stable in the process of operation, maintenance, control and automation of all kinds of electrical equipment in wind farm. It is to give full play to communication, data processing, data analysis, Data storage and professional performance index analysis and other automation advantages, especially in the gradual realization of the goal of unattended wind farm, not only for a single wind turbine remote monitoring, It is also necessary to integrate the substation and wind measurement equipment of the whole wind farm, as well as the establishment of the remote data center, and so on. By providing perfect real-time data reports, data processing and graphic display, the management personnel can be made convenient. On the basis of this, the system follows the principles of adaptability and openness, and can adapt to the special conditions of each wind farm at the same time. The wind power data acquisition and monitoring system organically interconnects different control systems of various units, so that all kinds of information and resources can be effectively coordinated into a whole, with sufficient flexibility and expansibility. It can adapt to the changes of internal and external environment in time, and consider the seamless embedding of wind energy prediction, reliability maintenance and emergency dispatch modules. In recent years, a variety of wind power data acquisition and monitoring systems have been developed in China. In the course of the research on this subject, we read more cases of wind power generation in our country on the application of SCADA system, which is mainly used in SCADA system, which is mainly used in data acquisition and monitoring, in the course of the research of this subject, we read more cases of wind power generation in our country on the application of SCADA system. Then combining with the corresponding technology adopted in the corresponding fields in Germany, the paper designs the framework of wind power network system architecture. SCADA, which combines SCADA system with network technology, is based on a single wind power generation monitoring and control automation system. Combined with Internet technology and database technology, it can realize data acquisition and monitoring between wind turbines, and at the same time, consider the remote diagnosis of wind turbines in the event of errors or other failures, and so on. To realize the automation and remote implementation of wind power generation monitoring system based on data acquisition. The design of explosive multistage data cache processing system for SCADA system is carried out. The data receiving module is used to receive the data storage request message sent by application program. The data prereading module inserts the data storage request stored in the file cache module into the cache queue, and the data optimization module reads the data storage request in the cache queue. After the data storage request is optimized, the idle thread in the thread pool is called, and the data storage operation is executed. This subject can solve the security problem of the request data and the SCADA system when submitting the massive data storage request.
