The invention relates to a wind collecting vertical type wind power generating system which comprises a wind power system, a vertical type speed increaser, a vertical type generator and an excitation grid-connected control system, wherein the wind power system is connected with the speed increaser and the generator by a chain coupling; the generator is controlled by the excitation grid-connected control system; the wind power system is in a box frame structure and comprises a fan blade system and a wind collecting and protecting system; the upper end and the lower end of a box frame are respectively provided with an upper shed top and a lower shed plate; the wind collecting and protecting system comprises a plurality of wind collecting plates which are distributed at four sides of the boxframe and hydraulic drive equipment; the upper shed top, the lower shed plate and the wind collecting plates are connected to form a wind tunnel box type wind collecting body; the generator works in a multi-winding pole-changing control way; and the generator and the speed increaser are installed on the ground. The invention has the advantages of small size, low installation, maintenance and transportation cost, high wind power utilization ratio and wind field land utilization ratio, stable performance, high storm wind resistance and favorable power generating quality and grid-connected performance, can form a high-power wind power generator unit system and is suitable for various weather and geographic environments.
