3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Wave energy
The kinetic and potential energy possessed by waves on the ocean surface.
[Source. GB/T 34910.3-2017, 3.1]
3.2
A device that captures wave energy and converts it into electricity.
Note. It consists of one or more wave energy generators, as well as power transformation and distribution systems, monitoring systems and auxiliary equipment and facilities.
3.3
response time
From the time when the control command is received until the actual output change of the observed variable of the wave energy power generation device reaches the control target value and the initial value for the first time
The time required for the difference from the initial value to be 90%.
