　　加纳布维水电站工程位于加纳(Ghana)西部的黑沃尔特(Black Volta)河上，坝址以上控制流域面积123,000km2，坝址处多年平均流量207m3/s，多年平均径流量65.23亿m3，工程主要使命为发电和浇灌。布维水电站水库正常蓄水位183m NLD，响应库容125.7亿m3；死水位168m NLD，调理库容55.2亿m3，具多年调理能力。枢纽修建物由挡水坝、进水口、压力钢管及地面厂房等组成。引水系统接纳“单机单管”安排形式，尾水系统每台机单位安排。电站装机容量400MW(3?133.34MW)，包管着力342MW，多年平均发电量10.04亿kW·h，本电站出线电压品级为161kV，出线4回，一回至NEW KUMASI变电所，送电距离212km，一回至TECHIMAN变电所，送电距离约104km，一回至KUMASI变电所，送电距离219km，一回至WA变电所，送电距离约231km。我司承制该项目共有8台（套）液压启闭机，其中3台（套）3200KN/1600KN电站进水口液压启闭机，1台（套）630KN/250KN小机进水液压启闭机，5台（套）2500KN溢洪道表孔液压启闭机。

The Bui Hydropower Project is located on the Black Volta River in western Ghana. The controlled watershed area upstream of the dam site is 123,000 km?, with a long-term average flow rate of 207 m?/s at the dam site and an average annual runoff of 6.523 billion m?. The primary purposes of the project are power generation and irrigation. The normal storage level of the Bui Hydropower Station reservoir is 183 m NLD, with a corresponding storage capacity of 12.57 billion m?. The dead water level is 168 m NLD, providing a regulated storage capacity of 5.52 billion m? and multi-year regulation capability. The hub structures consist of a water-retaining dam, intake structures, penstocks, and an above-ground powerhouse. The water diversion system adopts a "one-penstock-per-unit" layout, and the tailwater system is arranged per unit. The installed capacity of the power station is 400 MW (3 × 133.34 MW), with a guaranteed output of 342 MW and an average annual energy generation of 1.004 billion kWh. The power station's outgoing line voltage level is 161 kV, with four lines: one to the NEW KUMASI substation (transmission distance: 212 km), one to the TECHIMAN substation (transmission distance: 104 km), one to the KUMASI substation (transmission distance: 219 km), and one to the WA substation (transmission distance: 231 km).

Our company was contracted to supply a total of eight (8) sets of hydraulic hoists for this project, including:

Three (3) sets of 3,200 kN/1,600 kN hydraulic hoists for the power intake;

One (1) set of 630 kN/250 kN hydraulic hoists for the small unit intake;

Five (5) sets of 2,500 kN hydraulic hoists for the spillway surface outlets.
