【摘要】：胜利油田滨海电网管理的变电站多,造成运行人员生产性缺员,运行人员工作时间超劳动法要求,对职工身心健康和安全运行造成一定潜在影响。为了解决缺员和降低劳动强度,进行变电站无人值守的是一条切实可行的途径。通过对变电站无人值守方案的研究,对比各类方案,优选出适合滨海电网的无人值守改造方案,尤其对方案的适用性、兼容性以及针对电网中的管理和应用的特殊性等方面进行研究,确保满足油田电力要求。规划三个集控中心,即新孤集控中心、海洋集控中心和东一集控中心,在这三个集控中心安排人员监控,将其它变电站进行无人值守变电站改造。通过这三个集控中心对周围无人值守站进行监视控制等,从而解决人员紧缺和安全运行等矛盾。无人值守是一个容微机保护、网络通讯、后台监控及远方视频等技术与一体的综合性系统,除此之外,还面临着诸多现场和实际的问题,集控中心功能的界定,需要达到技术指标,如何设置集控中心,无人值守变电站要达到标准,相应一二次设备的改造,通讯的配置等,以及无人值守变电站建立以下如何运行管理等。该项目主要创新点：多种软硬技术融为一体,运用了微机保护,网络通讯和后台信息处理等,采集数据量大,功能强大,兼容性强；实现了实时数据采集、遥测、遥信、遥控、遥调、数据报表等功能；适用于各种恶劣运行环境,可靠性强；采用双机备份、操作记录、故障录波、实时报警等技术提高了系统的可靠性,实现了真正的无人值守。项目的实施具有良好的经济效益和社会效益,集控中心范围内的开关操作都可以在本站内完成,而且对故障进行分析、判断,既节约了人工,又减少中间环节。该研究的实施极大地提高了油田变电站的安全、可靠,减少值班员劳动,实现减人增效,满足油田电力发展的要求。
[Abstract]:There are many substations in seaside power grid management in Shengli Oilfield, which result in the productive shortage of workers, the working hours of the operators exceed the requirements of labor law, which have a certain potential impact on the health and safety of the workers and staff. In order to solve shortage and reduce labor intensity, unattended substation is a feasible way. By studying the unattended scheme of substation and comparing all kinds of schemes, the unattended reconstruction scheme suitable for coastal power network is selected, especially the applicability of the scheme. Compatibility and particularity of management and application in power grid are studied to meet the requirements of oil field power. Planning three centralized control centers, namely, the new solitary centralized control center, the ocean centralized control center and the East one centralized control center, the three centralized control centers arrange personnel monitoring to transform the other substations into unattended substations. The three centralized control centers are used to monitor and control the surrounding unattended stations, so as to solve the contradiction between the shortage of personnel and the safe operation. The unattended system is a comprehensive system with computer protection, network communication, background monitoring and remote video technology. In addition, it also faces many problems in the field and reality, and defines the function of the centralized control center. It needs to meet the technical target, how to set up the centralized control center, the unattended substation to meet the standard, the corresponding primary and secondary equipment transformation, the configuration of communication, and how to operate and manage the unattended substation. The main innovation points of this project are as follows: a variety of soft and hard technologies are integrated into one, the computer protection, network communication and background information processing are used, the data collection is large, the function is powerful, the compatibility is strong, the real-time data acquisition, the telemetry, the remote communication, the remote control are realized, Remote adjustment, data report, etc., which is suitable for all kinds of bad operation environment, and has strong reliability. The technology of double computer backup, operation record, fault recording and real time alarm is used to improve the reliability of the system and realize the real unattended system. The implementation of the project has good economic and social benefits, the switch operation in the centralized control center can be completed in this station, and the fault analysis and judgment can save both labor and intermediate links. The implementation of this research has greatly improved the safety and reliability of oil field substation, reduced the work of shift workers, realized the reduction of human resources and efficiency, and met the requirements of oilfield electric power development.
