摘要：It is intended to provide a power generating apparatus of renewable energy

type installed with a cooling mechanism which is capable of efficiently cooling operatingoil of a hydraulic transmission. The power generating apparatus of renewable energytype 1 is provided with: a tower (2), a nacelle (4) which is supported rotatably by a tipportion (2B) of the tower; a main shaft (14) which rotates with a blade (6B); a hydraulicpump (8) which is housed in the nacelle and is driven by rotation of the main shaft (14); ahydraulic motor (10) which is driven by operating oil supplied from the hydraulic pump(8); a generator (12) which is coupled to the hydraulic motor (10); an operating-oil line (30)which is provided between the hydraulic pump (8) and the hydraulic motor (10) andthrough which the operating oil circulates; a cooling-medium line (40) through whichcooling medium for cooling the operating oil circulates via an intermediate heatexchanger; and a main heat exchanger (51) which cools the cooling medium by heatexchange with cool water source which is one of sea water, lake water, river water andgroundwater around a base portion of the tower, and one of the operating-oil line (30)and the cooling-medium line (40) includes: a first piping (31, 34) supported on a nacelleside; a second piping (32, 33) supported on a tower side; and a connection part (100)connecting the first piping and the second piping so that the first piping (31, 34) and thesecond piping (32, 33) are relatively rotatable.
