The invention discloses an intelligent test platform for a hydraulic brake system of a wind turbine generator unit. The intelligent test platform comprises a PLC measurement and control unit, a high-speed shaft brake unit and a yaw brake unit which are connected with the hydraulic brake system to be tested, wherein the high-speed shaft brake unit comprises a first flow sensor, a first pressure sensor, a first displacement sensor, a high-speed shaft brake and a high-speed shaft brake disc; the yaw brake unit comprises a second flow sensor, a second pressure sensor, a yaw brake, and a yaw brakedisc; and the PLC measurement and control unit controls electric control valves in the hydraulic brake system, acquires test data of the sensors in the high-speed shaft brake unit and the yaw brake unit, and realizes detection on high-speed shaft brake performance and yaw brake performance of the hydraulic brake system. The intelligent test platform can realize the performance detection on a high-speed shaft brake loop an
