---Muong Hum Hydropower Station in
Viet Nam, designed by Zhejiang Zhongzhou Water Resources
and Hydropower Planning and Design Co., Ltd. of HRC, wasconnectedfor
power generation officially on 18th April 2011.
Muong Hum Hydropower is located in
Lao Cai Province in the northwest of the Socialist Republic
of Viet Nam. The project is located on Muong Hum River,
a left-bank branch of Aifahe River which is a first level
tributary on the right bank of Red River. The dam site
is located at east longitude 103¡ã42¡ä30¡åand north latitude
22¡ã32¡ä30¡å, only 2km away from Muong Hum Town and connected
with the powerhouse by a highway of 7 km. The power house
is on the right bank of the downstream river course (Shun
River), 3.6 km away from the dam site and located at east
longitude 103¡ã44¡ä30¡åand north latitude 22¡ã32¡ä30¡å, with
a distance of 22 km from Bat Xat Town and 40 km from the
capital of Lao Cai Province. The catchment area of the
dam site is 347.1 km2 and the surface area of power house
is 360.1 km2.
Muong Hum Hydropower Station is a kind
of Run-of-the-River hydropower plant. The hydraulic complex
is composed of the concrete gravity dam (with a spillway,
the maximum height of the dam: 30.5 m ), upper horizontal
diversion section of the tunnel (length: 2527m), surge
tank, vertical shaft, lower horizontal section of the
tunnel, power house, sub-station of 110 kV etc. With designed
head of 110m, two vertical Francis units and installed
capacity of 2¡Á16MW, the project has the main objective
for generation. The reservoir is constructed with the
normal capacity of 1.91 million m3,and a total volume
of 2.14 million m3.
The two transmission lines of the Muong
Hum Hydropower Station are connected to No 2 Lao Cai 110
kV Transformer Station (length: 32 km) and NAMPHUN 110
kV Transformer Station (length: 5 km) respectively.
Muong Hum Hydropower Station is a key
project in Lao Cai Province, Vietnam. The successful grid-connected
electricity generation of this project had effectively
mitigated the power supply shortage situation in the north-western
area of Viet Nam. (2011-12-27)
