Characteristics Investigation for Hydro-Mechanical Compound Transmission in Wind Power System
Aiming at the problem of variable speed constant frequency (VSCF) in wind power system, a design scheme of power split type compound hydraulic mechanical continually variable transmission (HMCVT) used in wind power system is proposed. With variable speed input and constant speed output as the premise, the design scheme combines the characteristics of hydraulic high power density, stepless speed change and mechanical high efficiency by means of power split. Its static speed and efficiency properties are theoretical analyzed. Combined with the actual working conditions, the Matlab/Simulink software is used for modeling the HMCVT wind power system, dynamic simulation and analysis. Finally, the transmission test platform had been built, and the experimental data and simulation results are basically the same. The results show that the HMCVT wind power system can realize VSCF. Its dynamic characteristics are good, and efficiency can be stabilized at around 87%.
