Semi-physical Simulation Test-stand for Electro-hydraulic Proportional Pitch-controlled Wind Turbine System
Abstract:
In order to solve the evaluation problems of the performance and reliability of the controller and electro-hydraulic actuator in the study of pitch-regulated control technology, a semi-physical simulation test-stand for electro-hydraulic proportional pitch-controlled wind turbine system is built. This paper introduces in detail the four major parts of the test-stand which are simulation models of wind turbine, electro-hydraulic proportional system of pitch controlling , wind moment load-on equipment, and controller, expounds its research and development functions and verifies further the rationality of the design by test result curves.
