After more than 10 months of repair, Mangdechu hydropower plant’s turbine number three resumed power generation yesterday.
The 720MW plant shut down its turbine number three on September 20 last year. The management had targeted to complete the repairs by August 20. The turbine was connected to the grid after completing all necessary tests. The four turbines together generated 765MW yesterday, according to sources in MHPA.
A flashover burnt and carbonised the stator (a stationary part of a rotary system) windings and other rotor components inside the generator causing an electric short-circuit.
It was learnt that in monsoon all the four units generate around 197MW each, which is 10 percent additional power above their capacity.
MHPA was completed in 2020 within seven years at a cost of Nu 51.442 billion. Each of the four units generates 180MW of electricity.
