The rotor of Unit #5, an underground power station on the left bank of
Wudongde Hydroelectric Power Station Project, was successfully installed by Energy
China CGGC Group who undertook the construction work of the project, signaling
that the installation of the unit is entering the assembly phase.
The installation of left bank underground
hydropower units is undertaken by Energy China CGGC Electrical & Mechanical
Co., Ltd.. Hundreds of staff stayed at the site during the Spring Festival.
After launching the emergency response to public health crisis, the project
department accomplished the duties in epidemic prevention and control, and
simultaneously promoted the installation of six 850MW hydropower units
scientifically and orderly.
Wudongde Hydroelectric Power Station is the
fourth largest hydropower station in China and the seventh largest hydropower
station in the world. The rotor of Wudongde Hydroelectric Power Station
generator set is the largest hoisted fitting among the constructing hydropower
stations in the world. The rotor of Unit #5 weighs 2,100 tons.
This is the third 850,000-kW turbine generator
unit at the Wudongde dam that has completed the rotor installation.
The turbine generator rotors installed at the
Wudongde dam are among the largest assembled pieces that have been hoisted for
a hydropower station project under construction in the world.
The generator rotor installed at unit 5 weighs
2,100 tons with a maximum diameter of 17.5m and a height of 4m, one of the
heaviest components of the hydro-generator unit at the Wudongde hydropower
station. The completion of rotor installation for Unit 5 brings the project one
step closer to meet the operation target by July 2020.
Wudongde hydropower station will house 12 units
of 850,000-kW turbines with a combined installed capacity of 10.2 million
kilowatts. The first batch of its units is scheduled to be officially put into
operation in July 2020 after commissioning in May and trial operation in June.
All of the 12 units will be fully operational in 2021.
Wudongde hydropower station, owned and built by China Three
Gorges Corporation (CTG), completed the concrete pouring for No. 2 and 14 dam sections.
Currently, the number of dam sections that have completed
the concrete pouring amounts to five, which lays a solid foundation for its
first batch of units to start operation in July 2020 on schedule.
All participating units working at the Wudongde Dam have
maintained the construction work uninterrupted while giving the highest
priority to the safety and health of staff at the site as they stepped up the
efforts to fight the epidemic to ensure smooth operations.
Nearly 2,000 builders are now working at the site of
Wudongde project for jobs such as concrete production and pouring and no
infected case has been reported so far.
