Research on the Drive Control Method of Rotating Machinery in Grid Connected Photovoltaic Generating Units
In order to maximize the absorption of solar energy,the grid connected photovoltaic generator set needs to rotate the mechanical device at the bottom of the panel,so that the direction can be adjusted at any time to ensure the power generation efficiency.Therefore,an effective control method for rotating mechanical drive of grid connected photovoltaic power generation units is studied.Calculate the transient response of grid connected photovoltaic genera-tor units and the dynamic unbalance of rotating machinery,and obtain the operating status of rotating machinery.By combining automated control technologies such as virtual synchronous generator control strategy,PI regulator,and on-tology algorithm,a rotating machinery drive control model is established to control the output power of grid connected photovoltaic power generation units to reach the initial oscillation amplitude,achieving drive control of rotating ma-chinery.The experimental results show that the vibration amplitude of this method does not exceed 0.6 cm,the aver-age control response time is 1.28 s,and the loss of control rate does not exceed 7.5％,it has good driving and con-trol capabilities.
