[摘 要]信息化阀室在天然气长输管道生产运行中起着较为重要的作用,随着管道管理自动化、信息化水平的逐步提高,负责数据采集和阀门控制的信息化阀室越来越多,但这些阀室所处的地理位置各不相同,多处偏僻地区,自然环境条件较差,供电方式多样,如供电中断将引起设备无法工作、通信中断、调度室无法监控,对运行调控产生影响。如何做好阀室供电管理成为了输气行业的迫切需求。文章从阀室供电现状、优缺点分析及存在的问题等方面进行说明,并从技术措施和管理措施两方面,对提高阀室供电可靠性方面提出建议。

[Abstract]Information valve stations play an important role in the production and operation of long-distance natural gas pipeline. With the gradual improvement of pipeline management automation and information level, more and more information valve stations are responsible for data acquisition and valve control, but these valve stations are located in different geographical locations, many remote areas, poor natural environmental conditions and diverse power supply modes, For example, power supply interruption will cause equipment failure, communication interruption and dispatching room failure to monitor, which will have an impact on operation regulation. How to do well in power supply management of valve chamber has become an urgent demand of gas transmission industry. This paper explains the current situation, advantages and disadvantages analysis and existing problems of valve chamber power supply, and puts forward some suggestions to improve the reliability of valve chamber power supply from two aspects of technical measures and management measures.

随着自动化、信息化技术及天然气管道输送行业的飞速发展,输气管道生产运行的安全性与自动化、信息化联系得越来越紧密。目前,输气管理处信息化阀室供电方式主要包括外供电、外供电+UPS后备方式、太阳能+蓄电池方式、外供电+太阳能+蓄电池方式这四种。但在现有四种供电方式下,仍旧存在着供电中断的隐患,如何提高信息化阀室供电可靠性,成为生产运行管理的迫切需求。
1 川渝地区阀室供电现状
1.1 阀室供电设计要求
国家标准GB 50251—2015《输气管道工程设计规范》中规定,阀室的供电电源应从所在供电营业区的电力系统取得。当无法取得外部电源,或经技术经济分析后取得电源不合理时,宜设置自备电源。……
