大庆油田110kV变电站微机综合自动化系统配置的研讨

Discussion of Automatic System Configuration of 110kV Substation for Daqing Oil Field

多年的运行实践表明,采用微机综合自动化技术在降低变电站运行、检修人员工作量,提高继电保护装置性能等方面都显示了巨大的优越性,是油田电网二次系统的发展方向。但随着微机综合自动化产品种类及生产厂家的增多,逐渐暴露出一些产品在保护定值项设置、软件升级管理等方面的问题。为保护油田电网安全运行,最大限度地利用微机综合自动化装置的软、硬件资源,对微机综合自动化技术进行了探索、研究和总结,并在新建变电所二次技术协议中应用。论述了油田电网110kV变电所微机综合自动化系统配置。

The operating results show that automation technology based on microcomputer is advantageous at reducing the work of operating and maintenance staffs, improving relay performance and it抯 the tendency of secondary system of the grid. In view of safe operation of the grid, the configuration of automatic system of 110kV substation is proposed.
