变电站实体安全措施电子化替代研究

Research on the Electronic Replacement of Substation Physical Security Measures

安全措施的准确布置是保障变电站检修安全和运行安全的重要措施之一,传统实体安全措施存在搬运不便、易脏旧、在雨雪天气布置拆除麻烦等问题,考虑到未来变电站智能化、自动化的发展趋势,提出一种变电站实体安全措施电子化替代方案。通过主控室安全措施控制中心与现场箱柜安全措施布置终端的双层通信架构,在现场工作的设备、箱柜、屏柜处提供清晰明显的指示灯和语音信号,实现对传统围栏围网、标示牌和红布幔等实体安全措施的有效替代,不仅能辅助人员准确辨识待检修设备、不误动来电侧隔离开关等,而且能够一键布置拆除,极大地降低变电站的安全措施布置工作,提升变电站运维工作的自动化水平和运维管理效率。

The accurate arrangement of security warning and enclosure are important approaches to ensure the maintenance safety and operation safety of the substation.In view of problems existing in traditional physical security measures,such as inconvenient transportation,easily stained,and trouble in arrangement and removal in rainy and snowy weather,etc.,an electronic replacement method of substation physical security measures is proposed considering the development trend of intelligence and automatization of the substation in the future.Through the double-layer communication structure between security measures control center in the master control room and security measures terminal in the terminal box,mechanism box and protection devices,the proposed method provides clear and obvious indicator visual and audible signals on-site to effectively replace the physical security measures of the traditional fence,warning board and red cloth curtain.This does not only assist personnel to identify the equipment to be overhauled and avoid accidentally move of the incoming isolation switch,but also arranges and removes security measures with one key in the master control room,which greatly reduces the arrangement work of security measures and improves the automation level and operation management efficiency of substation.
