[Hydropower] Efficient and clean energy must be equipped with efficient and comprehensive detection methods

Key points of testing for hydroelectric power plants

For hydroelectric power generation, the operating efficiency of the turbine blades determines the final power generation efficiency, which also places high requirements on the detection of the turbine blades, especially the roots of the blades
.

(Sectional drawing of hydroelectric power plant )

During the normal operation of a hydroelectric power plant, the blades will produce a certain amount of fatigue loss.
At the same time, there are inevitably some sand and pebbles in the water, which will also cause certain damage to the blades
.
In addition, considering that certain defects may occur in the welding team of the blade, the blade inspection is particularly necessary
.

Case Sharing: Water Turbine Runner Blade Inspection

The following is an application case for the detection of turbine runner blades:

(Appearance of water turbine)

As an important part of the hydroelectric power plant, the inspection of hydraulic turbines is very important
.
Through the daily in-service inspection of the runner blades, most accidental failures can be avoided, so as to avoid the reduction of power generation efficiency due to the overall failure of the hydropower station
.

In this case, the detection method of double-sided and single-sided scanning along the line was adopted, and the Omniscan MX2 equipment was used for data collection, and the detection results obtained by using Tomoview offline analysis software:

(Blade 1)

By observing the screen of the instrument, we can easily determine whether the No.
1 blade is damaged, and we can also conclude that the No.
1 blade can pass the inspection
.

(Leaf 2)

Similarly, we can also observe the No.
2 blade and find that there are many defects in the No.
2 blade, which cannot pass the inspection and needs to be repaired or replaced in order to continue to maintain work efficiency
.

The estimated lifespan of hydroelectric power plants is usually over a hundred years, which is much longer than other types of power plants
.
For hydroelectric power generation, regular inspections to ensure the safe operation and management of facilities are the top priority, which is also the core factor for hydropower facilities to supply electricity for a long time
.
