Variable Motor of Main Transmission System in Wind Turbine Grid Connected Control in Fixed Displacement Pump-Parallel
摘要
Abstract
A grid connected control method was presented herein,which was used in the main transmission system of the fixed displacement pump-double parallel variable motor in hydraulic wind turbine,namely when the first variable motor worked in the state of grid connected,another variable motor didn’t lose stability in startup under the constant pressure control method.The rotate speed coupling of the double parallel variable motor was eliminated with the principle of structure invari-ance,therefore,when another variable motor was post-launch,the grid connected synchronous rotate speed was controlled under the speed control method.Meanwhile,the grid connected control mathe-matical model was established,and simulation was conducted.With pressure and speed control,the fixed displacement pump rotate speed,the variable motor swashplate angle,the variable motor rotate speed and the system high pressure response characteristics in the process of grid connected were ob-tained under the condition of different wind speed (fixed-displacement pump rotate speed).The grid connected control method was verified in the fixed displacement pump-double parallel variable motor. This reserach lays a theoretical foundation to expand the hydraulic wind turbine in the applications of large and super large wind turbine.关键词
