This paper analyzes power generation from sea waves by using power conditioning system and linear permanent magnet generator. A buoy is placed on the ocean surface and connected to the linear generator. The wave energy is carried out from the movement of a buoy. An electrical conversion system is needed between the generator and the grid. For an analysis of the power system, the modeling of the linear generator and converter system was proceeded, under the irregular wave condition. This paper aims at studying the electrical part of the wave energy converter and study what impact the electrical system will have on the generator.
