鄂曲水电站冰冻期运行安全措施论述

On safety measures for operation of Equ Hydropower Station during frost period

鄂曲水电站地处高原高寒地带,冬季气温低,河水冰冻时间长,电站建设和运行面临防治冰冻灾害等诸多问题,本文根据该电站所处地域的自然气候条件和枢纽设计布置,以及电站建设和冬季运行实践,对国内寒冷地区水电站的相关经验进行了分析研究,总结提出了防冰冻设计和措施。这对高寒地区水电站冬季运行具有一定参考作用。

Equ Hydropower Station is located within an alpine region with lower temperature and longer frost period during winter, and then many problems from the frost disaster prevention are encountered during the construction and operation of the hydropower station. In accordance with the natural climate condition therein and the designed layout of the project as well as the practices of both the construction and operation of the hydropower station in winter, the relevant experiences from the hydropower station located in cold regions of China are analyzed and studied herein; from which the related anti-frost designs and some countermeasures concerned are summarized and presented. All of these have some reference values for the operations of those hydropower stations within alpine regions.
