长距离输水无防护抽水断电过渡过程分析

Analysis of the Transient Process of Pumping Power Failure without Protection for Long-Distance Water Conveyance Project

文章以广东省西部某长距离管道输水工程作为研究对象,对该工程的管线系统进行水力过渡过程仿真计算,分析该系统内泵站在实际运行期间的不同工况下可能发生的抽水断电事故对输水系统造成的危害,提出了水锤防护措施,为泵站及输水工程的设计及安全运行提供决策依据。

This article takes a long-distance pipeline water conveyance project in western Guangdong Province as the research object,carries out the simulation calculation of the hydraulic transition process of the pipeline system of the project,and analyzes the harm caused to the water conveyance system by the pumping power failure that may occur under different working conditions during the actual operation of the pumping station in the system.The water hammer protection measures have been proposed to provide decision-making basis for the design and safe operation of pumping stations and water conveyance projects.
