This invention provides a tension leg floating foundation, a construction method, and a wind turbine generator set. The tension leg floating foundation includes: a floating body, comprising a main column and connecting bodies spaced apart around the main column. The main column is used to connect to the wind turbine body, and one end of each connecting body is connected to the second end of the main column. Multiple tension assemblies are spaced apart around the floating body. Each tension assembly includes tension legs and a mooring connection. One side of the tension leg is universally connected to a connecting body, and the other side protrudes from the connecting body towards the first end. The mooring connection is located on the side of the tension leg that protrudes axially from the connecting body. A mooring cable is provided for each tension leg. Each tension leg has a clearance cavity extending axially through it. One end of the mooring cable is inserted into the clearance cavity and connected to the mooring connection, while the other end is used for connection and fixation to the seabed. This invention can reduce the difficulty and cost of wind turbine foundation construction.
