塔贝拉电站位于巴基斯坦北部,该电站第三期扩建工程11～14号机组(单机容量440MW)于1992年投入运行。该电站是具有灌溉、发电的综合水利工程,其总装机容量达3510MW,除前苏联外,是中东和远东地区的最大水电站。本文叙述了电站的沿革及其布置,论述了有关宽水头范围的水力设计准则,概述了按 IEC 标准全相似模型试验的范围及主要试验结果。另外,本文还简单介绍了水轮机主要部件的主要结构特点以及相应的工艺方法。
Tabela station is located in northern Pakistan, the third phase of the expansion project 11 to 14 units (single capacity 440MW) put into operation in 1992. The power station is an integrated irrigation project with power generation. With a total installed capacity of 3510MW, it is the largest hydropower station in the Middle East and Far East with the exception of the former Soviet Union. This paper describes the evolution and layout of power stations, discusses the hydraulic design guidelines for the wide head range, and outlines the scope and main test results of the fully similar model test according to IEC standards. In addition, this article also briefly introduces the main structural features of the main components of the turbine and the corresponding process method.
