A Study of a Generator Efficient Testing Method that Incorporates Tidal Limitations
- 발행 : 2013.02.28
초록
Tidal power generation is to produce electrical energy from fluctuations of the ebb and flow in a constructed embankment. More specifically, the sinusoidal variations of tidal flow, along with the periodicity and changes in the height of waves over time make the tidal power generation possible at a certain tidal level. This paper proposes a more practical efficiency test method for tidal power plant generator that utilizes the axis torque changing values rather than the retardation method which is commonly used. The proposed method was compared with the conventional method and the test result shows that proposed method provides a similar accuracy with the conventional retardation method and a better efficiency.
