Abstract
The tidal power station system is the study object in mooring state, and model tests are carried out to study the motion characteristics of the carrier and mooring chains in uniform wave with different wave parameters while equipped with the hydraulic turbine and equipped without the hydraulic turbine. Motion characteristics of the carrier in the free state is checked in tests. When test data match calculating data, tests will be conducted to research on motion response of the carrier in mooring state and dynamic characteristics of mooring line. The motion pattern of the tidal power plant carrier in wave and flow is obtained through comparative analysis of test results.
