Quality Appraisal of Hydropower Station Generator Units

The function of a hydroelectric generator set is to convert water energy into rotating mechanical energy, thereby driving a generator to emit electrical energy. It is one of the power equipment of a hydropower station.

The basic principle of hydropower is to use the water level difference to generate electricity with a hydroelectric generator. That is, the potential energy of the water is converted into the mechanical energy of the hydroelectric wheel, and then the mechanical energy is used to drive the generator to obtain electricity.

Zhongke Testing and Appraisal Institute can provide quality appraisal services for hydropower station generator sets and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

1, hydraulic turbine generator set
hydraulic turbine generator set is one of the most common types of generators in hydropower stations. Its basic components include turbines, generators, speed regulators, hydraulic control systems, unit cooling systems, etc.
2, horizontal axis turbine
is different from the hydraulic turbine generator set. The horizontal axis turbine directly acts on the rotating impeller to drive the generator to rotate. Its characteristic is that it can generate electricity using water sources such as small rivers, reservoirs, and lakes.

3, vertical axis turbine
The impeller of the vertical axis turbine is at right angles to the axis. Its structure is simpler than the above two generator sets. It is often used in situations where flow, load size and stable quality are required.

According to the information provided by the client, Party A and Party B signed the "XX Hydropower Station Contract". According to the agreement between the two parties, Party B paid Party A a resource fee of 160KW for each generator and a total of 320KW for two generators. However, Party A later discovered that the actual installed capacity of the hydropower station was more than 160KW for a single unit and more than 320KW for the two units combined. The two parties had a dispute over the actual installed capacity of the hydropower station. In order to further clarify the facts, Party A proposed to appraise the actual installed capacity of the generating units of the "hydropower station" involved.

Appraisal analysis results:

The appraisal expert group discussed and comprehensively analyzed the relevant information and on-site investigation and inspection of the "hydropower station generator set" involved in the case, and made the following appraisal opinions:

The actual installed capacity of the "hydropower station generator set" involved in the case should be in the range of 500KW ~ 640KW.
