PURPOSE: A high altitude wind power generation system for mounting a cycloidal turbine is provided to maintain a stable posture while staying at a high altitude by sequentially arranging a cycloidal turbine and a generator in the lower side of a buoyancy tool. CONSTITUTION: A high altitude wind power generation system for mounting a cycloidal turbine comprises a buoyancy tool(10), a cycloidal turbine(20), and a generator(30). The buoyancy tool is expanded by injecting a buoyancy generative gas to the inside. The cycloidal turbine comprises a rotary shaft(21) and a blade(22). A plurality of blades is arranged in the circumferential direction of the rotary shaft by extending a pitch center line(P) to be aligned with a rotary shaft center line(C). The blade is separated from the rotary shaft at a predetermined distance with the arrangement of the pitch center line to be vertical to the flowing direction of air from the front side. The blade separately adjusts a pitch angle on the pitch center line. The blade rotates on the rotary shaft in the alignment of the rotary shaft center line with the pitch center line. The generator is connected with the rotary shaft of the cycloidal turbine and generates power by receiving the rotation force of the rotary shaft. The cycloidal turbine and generator are arranged in the lower side of the buoyancy tool.
