“西气东输”上游地面建设工程中的电气设计特点和应对措施

THE DESIGN CHARACTERISTICS OF THE ELECTRICAL INSTALLATION IN UPST REAM SURFACE CONSTRUCTION OF WEST-TO-EAST GAS TRANSMISSION PROJECT AND THEIR CORRESPONDING MEASURES

电力作为一种商品 ,其生产和消费的连续性极高 ,并且在数量上严格要求供需动态平衡。作为传输电力的供配电网络设施 ,它是一切现代工业生产企业的最重要的基础设施之一。文章以系统工程的观点全面介绍了我国西部大开发中的“西气东输”工程上游源头塔里木气田和长输管线起点工程的供电电源、供配电网络和供配电设施的设计思想 ,其中着重介绍针对新疆地区的特殊环境 ,在电力负荷等级的确定与产能配套的供配电系统及其设施的可靠性设计方面所采取的对策 ,还介绍了供配电网络优化和如何选用成熟技术和产品的具体措施。

As a commodity, the electric power requires its production and consumption to have a very good continuity and a strict equilibrium between the supply and demand, but the electricity supply and distribution network is one of the most important infrastructures for all modern industrial enterprises. In this paper, from the point of view of System engineering, the design thought of electricity supply source, electricity-supply network and installations and electricity-distribution network and facilities in the Talimu gas field - the upstream fountainhead of the west-to-east gas transmission project and at the starting point of the long-distance pipeline in the large-scale development of the West region of China is overall introduced, of which, the countermeasures adopted in the determination of electric load grade and the reliability design of the supply and distribution system assorted with the deliverability and its installations are emphatically presented in view of the special surroundings of Xinjiang region. The optimization of electricity supply and distribution network and the concrete measures for selecting ripe technique and products is presented also.
