Wanxiang-II

It was installed in 2005 and consist of a bottom fixed vertical-axis tidal current energy plant, which has two H-shaped rotors with adjustable-angle blades and a vertical axle. It consists of a cabin, a pontoon, a cone, a caisson and riggers. The device differs from Wanxiang-I in that it is located on the seabed to avoid damage from typhoons, and it transports power to shore through seabed cables, where the power is converted and regulated to be used for a lighthouse. It can float to the surface when it requires maintenance. In the years since its deployment, Wanxiang-II has been proven to have improved energy conversion efficiency over Wanxiang-I. The device consists of two 20 kW straight-blade vertical rotors, driven system and a platform. The platform consists of turbine nacelle, caissons and fixed legs. As a totally submerged system, the driven system and the generator are tightly sealed in the turbine nacelle.
