Pressure Control Characteristics of Main Transmission System of Hydraulic Transmission Wind Energy Conversion System
摘要
Abstract
Fixed displacement pump-variable displacement motor is the main drive system of hy-draulic type wind turbine,the system is controlled by a variable displacement mechanism after grid-connected.To study the pressure control characteristics,a mathematical model was built and the trans-fer function describing the pressure to the position of the motor swash plate was derived.Compared with the identified model obtained from data identification in MATLAB system,the built model was verified,which laid theoretical and test foundation for further maximum power point tracking(MPPT) based on pressure control in hydraulic type wind turbine.关键词
