【摘要】：广播电视的“安全播出”涉及到国家安全和社会稳定,一直来都是广电行业高度重视的一项工作。其中,电力保障在广播电视“安全播出”评估系统中占了比较大的分量,各地广电中心的工艺供配电系统的安全、可靠、先进性对其“安全播出”保障起着至关重要的作用。江西广电中心变电站主要承担着江西广播电视安全播出系统的电力保障工作,是江西广播电视各安全播出单位的工艺供电系统的主要的源头。为满足江西广播电视事业未来发展的供电需求,扩大变电站输出容量,提升其综合自动化水平,在“高质量,不间断,既经济,又安全”的“安全播出”总方针指导下,对江西广电中心变电站进行在原址的更新改造。变电站改造工程涉及到很多环节,而变电站数据通信及监测系统的设计是其中重要的一项。本设计依据小型变电站数据通信及监测系统的特性标准,基于RS-485现场总线方式,以标准的Modbus为主要通信协议,将现场各需要通信和监测的智能电子装置组合规划,运用通信管理机完成相关的通信网络连接和规约转换,然后通过工业以太网交换机,与站内控制室的计算机服务器(监控主机)进行数据通信和监测管理。设计项目中,选用了国电南京自动化股份有限公司的EYEwin2.08厂站监控软件,采用了分层设计、组件化、标准化、开放式等软件开发思路,提供了可靠、安全、易于人员操作的变电站监控平台,实现变电站内各高压柜微机保护装置、高压侧智能电能表、变压器智能温控器、直流电源屏、低压侧数字电力参数测量仪、柴油发电机组等设备的数据通信和监测。变电站数据通信及监测系统的实现,对江西广电中心的电能质量监测、电力节能管理等工作发挥了非常重大的作用,显著提升了其综合自动化管理水平,加强了广播电视工艺供配电系统的安全可靠和先进性,为江西广播电视事业的发展解决了燃眉之急和后顾之忧。
[Abstract]:The "safe broadcasting" of radio and television involves national security and social stability. It has always been a work of great importance in the radio and television industry. Among them, the power security is a large part of the radio and television "safe broadcasting" evaluation system. The whole broadcast "guarantee" plays an important role. The substation of Jiangxi radio and Television Center is mainly responsible for the power guarantee of the Jiangxi broadcast and TV broadcasting system. It is the main source of the technology power supply system of the Jiangxi broadcasting and television broadcasting and television broadcasting units. Under the guidance of "safe broadcasting" of "high quality, uninterrupted, economical and safe", the power station's output capacity is promoted by the "safe broadcasting" general policy of "high quality, continuous, economical and safe". The substation renovation project of Jiangxi radio and television center involves a lot of links, and the design of substation data communication and monitoring system is one of them An important item, based on the characteristic standard of the data communication and monitoring system of small substation, based on the RS-485 field bus mode and the standard Modbus as the main communication protocol, the design of the intelligent electronic devices which need communication and monitoring in the field is combined, and the communication network connection and protocol conversion are completed by the communication management machine. Then through the industrial Ethernet switch, the data communication and monitoring management are carried out with the computer server (monitoring host) in the control room of the station. In the design project, the EYEwin2.08 station monitoring software of the Nanjing automation Limited by Share Ltd of Guodian is selected, and the software development ideas such as layered design, component, standardization, open and so on are provided. The substation monitoring platform which is reliable, safe and easy to operate, realizes the microcomputer protection device of high voltage cabinet in the substation, the intelligent electric energy meter on the high voltage side, the transformer intelligent temperature controller, the DC power screen, the low voltage side digital power parameter measuring instrument, the diesel generating set and so on, and the data communication and monitoring system of the substation. The realization of the system has played a very important role in the power quality monitoring of the Jiangxi radio and television center and the power conservation management. It has greatly improved the level of its comprehensive automation management, strengthened the safety, reliability and advanced nature of the radio and television technology for distribution and distribution systems, and solved the urgent and future of the development of the radio and television industry in Jiangxi.
