Abstract

It is intended to provide a diagnostic system and a diagnostic method for a hydraulic machine as well as a hydraulic transmission and a wind turbine generator, whereby abnormality of the hydraulic machine can be accurately diagnosed. A diagnostic system is for a hydraulic motor (10) having a rotation shaft (32), a cylinder (20), a piston (22) forming a working chamber (24) with the cylinder (20), a high-pressure valve (28) and a low-pressure valve (30) provided for the working chamber, and a converting mechanism (25). The diagnostic system is provided with a pressure sensor (72) for detecting a pressure of the working chamber (24) and an abnormality determination part for determining abnormality of the hydraulic motor (10) based on detection result of the pressure sensor (72).
