Overhaul of these power units served their operation in the upcoming flood season.

The workload during overhaul of these power units was examination, maintenance, repair and replacement of turbines, generators, power transformers and auxiliary systems; Adjustment and testing of the equipment after overhaul such as load balance, machine centering, insulation testing; then to start the power unit to test mechanical parts, perform short-circuit test, no-load operation, etc., thereby assessing the quality and performance of the power units.
