Dynamic test rig for linear generators intended for wave-power applications

A linear generator test rig that can provide realistic emulation of wave-float hydrodynamics and varying sea states is presented. Such a test rig is extremely useful for the development of power take-off algorithms prior to expensive deployment at sea. The test rig is discussed in the context of other potential solutions and existing test rigs, with the decisions that led to its conception highlighted. The proposed test rig has been built and the results from initial tests are presented. These tests confirm the test rig’s dynamic emulation capability and set the scene for future, more adventurous testing.
