Scope

GB/T 41342-2022 is the English-translated version of 潮流能发电装置功率特性现场测试方法.

GB/T 41342-2022 is the Chinese method for testing at sea the power performance of a tidal energy converter.

It gives the general provisions of the test, the measurement of the current speed, the measurement of the electrical power the device produces and the way its power performance - the power curve and the capture efficiency - is derived from the two.

It applies to the power performance test of tidal current devices in real sea conditions, whether grid connected or standing alone. Device developers, test centres and the bodies that verify a performance claim use it. Issued on 9 March 2022, it has applied since 1 October 2022.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Conversion efficiency

The ratio of the output energy of the tidal current power generation device to the input energy of the flow rate.

3.2 Equivalent diameter

The impeller diameter of the tidal power generator.

Note 1.For the horizontal axis tidal current power generation device, it refers to the diameter of the rotating impeller of the tidal current power generation device.

Note 2.For the vertical axis power flow power generation device, it refers to the diameter of the rotating impeller of the horizontal axis power flow power generation device equivalently transformed into the same swept area.

Note 3.The unit is meters (m).

3.3 Energy capture cross-sectional area

The area of the tidal current power generation device that captures the input energy of the tidal current.

Note 1.For the vertical axis tidal current power generation device, it refers to the swept area of the tidal current energy power generation device.

Note 2.For the horizontal axis tidal current power generation device without a shroud, it refers to the projected area of the sweeping area of the tidal current power generation device in the direction of the flow velocity.
