变电站遥视系统动力环境数据的集成与实现
|
摘要
目前变电站遥视系统还存在着不足和缺陷,影响着无人值班变电站的建设。变电站遥视系统的动力环境数据不全面、电力系统传输级别较低及其视频监控嵌入式的发展趋势,使得遥视系统动力环境数据的集成日益迫切。因此本文采用了VC面向对象编程技术、TCP/IP协议、电力通信IEC104规约、套接字和数据库等技术开发了以多功能设备控制主机和动力环境服务器为主体的动力环境数据系统。它们接入到现有的变电站遥视系统中实现变电站动力环境数据的集成。
多功能设备控制主机负责接入变电站的数据采集控制模块,如温度湿度采集器、消防安防模块,报警收集器、空调灯光控制器等。采集前端信息,并负责上传动力环境服务器,并将采集的信息统计显示在运行界面上。动力环境服务器上传前端采集信息并将管理服务器发出的控制指令转发到多功能设备控制主机进行控制。动力环境服务器和多功能设备控制主机采用了IEC104国家推荐电力通信规约通信。
动力环境数据的集成和实现是应变电站无人值班和变电站遥视系统的专业化而生的。它使对变电站环境的监控更加全面。专用的动力环境服务器提高视频传输的稳定性,同时也可以减轻视频流传输的压力,使系统更加稳定。采用IEC104规约通信协议可以满足不同主机和动力环境服务器的连接,具有较强的适应性和可扩展性,有效的避免重复投资。同时为多级变电站遥视系统构架的发展探索了道路。
The substation tele-video system still has shortcomings and defaults presently, which affects the construction of unattended substation. The uncomprehensivenesss of power environment data, the low-level transmission of power system and the development trend of embedded DVR makes it increasingly urgent to integrate the power environment data. So the power environment data system whose principal part is multifunctional equipment control mainframe and power environment server is developed by the object-oriented programming, TCP / IP protocol, IEC104 protocol, the socket and database technique. They can achieve the environment data integration by accessing to to an existing substation tele-video system.
Multifunctional equipment control mainframe responsibles foe the access of data acquisition and control module. Such as temperature and humidity collector, fire security module, the alarm collected, air-conditioning lighting controllers. It collects the environment data of substation, displays it on the interface of the program and sends it to the power environment server. Power environment server sends the environment data of substation to monitor server and transmits the command instruction to the multifunctional equipment control mainframe. IEC104 is used in the communication between multifunctional equipment control mainframe and power environment server.
The driving force of the integration and realization of power environment data is the unattended substation and the professionalization of the substation tele-video system. It mskes supervise of substation environment more comprehensively. The special power environment server improves the stability of the video transmision, which makes the system more steadily. IEC104 protocol can satisfy the access between different multifunctional equipment control mainframes and power environment server, which has good adaptability and expansibility, explores a new road for multipolar structure of substation tele-video system.
