Problems solved by technology

However, the current wave energy and tidal current energy test platforms are all single-function test platforms, which can only meet the test of wave energy generation or tidal current energy generation, and cannot simultaneously meet the test of wave energy and tidal current energy, which makes the application of the test platform limited. certain restrictions

In addition, the simulation of tidal current energy conditions is realized through the control of the drag motor, and the characteristics of wave energy power generation determine that the existing simulation methods for working conditions cannot be applied.
