Abstract

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 and a yaw brake loop of the hydraulic brake system to be tested, enriches the test means of research and test inspection of the hydraulic brake system of the wind turbine generator unit, is high in intelligent degree, and is convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of testing hydraulic brake systems of wind turbines, in particular to an intelligent testing platform for hydraulic brake systems of wind turbines. Background technique [0002] Existing wind turbines are designed with hydraulic braking systems to control the yaw braking of the wind turbines. The performance of the hydraulic braking systems is directly related to the reliable operation of the wind turbines. At present, the major OEMs' testing of the hydraulic brake system of wind turbines completely relies on the test reports of the hydraulic brake system manufacturers and their secondary component suppliers. The OEMs themselves lack the effectiveness of the hydraulic brake system performance test and factory inspection. Monitoring methods have caused many avoidable problems in the subsequent operation of the wind turbine hydraulic braking system. [0003] It can be seen that the above-mentioned existing wind turb...
