1 Scope

This standard provides methods for analyzing and describing theoretical tidal current energy resources based on estimation or direct measurement, which can be used to estimate tidal current energy resources

And predict the annual power generation capacity of each tidal current energy conversion device location:

This standard applies to the early stage of construction of tidal current power generation projects:

This standard applies to sea areas where tidal energy conversion device arrays can be deployed, including estuaries affected by tides:
