川气东送管道工程始于川东北普光首站,止于上海末站,设计施工难度极大。根据当前管道工程设计思路和原则,对整体设计进行优化。选用Stoner Pipeline Si mulator软件和PipelineStudio软件进行管网、压缩机、储气调峰的工艺优化计算;通过地图勾线、Google Earth验证、DEM数据和卫星遥感技术进行选线;结合生产实际,采用成套技术对管道强度和稳定性、管道穿跨越、水工保护及水土保持工程设计进行优化;压气站采用大功率VSDS配电设计,变电所的布置采用3层结构,选用可靠的自备电源为阀室供电,并在电力系统中使用“整体防雷”和高频接地网等技术;借助SCADA系统实现整个管道的动态管理和自动监控;贸易交接计量采用计量系统成撬方案;通信系统则采用MSTP/SDH光通信技术。
Sichuan-East gas pipeline project started in the first station of Puguang in northeastern Sichuan, ending at the end of Shanghai, the design and construction of great difficulty. According to the current pipeline engineering design ideas and principles, the overall design optimization. Choose Stoner Pipeline Si mulator software and PipelineStudio software to optimize the process of pipe network, compressor and gas storage and peak shaving; route selection through map hook-up, Google Earth verification, DEM data and satellite remote sensing technology; Technology to optimize the strength and stability of pipelines, pipelines across, hydraulic protection and soil and water conservation engineering design; compressing station using high-power VSDS power distribution design, substation layout using three-tier structure, select a reliable self-powered Valve room power supply, and in the power system using “overall lightning protection ” and high-frequency grounding network and other technologies; with SCADA system to achieve the entire pipeline of dynamic management and automatic monitoring; custody transfer measurement system using metering system into pry; communication system MSTP / SDH optical communication technology is adopted.
