Energy-saving control technology of frequency conversion speed regulation for electric traction drum shearer
Energy-saving control of frequency conversion speed regulation process of electric traction drum shearer can increase the eco-nomic benefits of coal mining enterprises.In order to reduce the energy consumption of frequency conversion speed regulation of electric traction drum shearer,an energy-saving control technology of frequency conversion speed regulation of electric traction drum shearer was proposed.The MG180/435-W type electric traction drum shearer was selected as the experimental object,and the energy consumption control of the electric traction drum shearer was realized by using frequency conversion speed regulation device.Through the kinematics analysis of electric traction drum shearer,the energy consumption control scheme of frequency conversion speed regulation device of e-lectric traction drum shearer was formulated.Under different schemes,the frequency converter of shearer was started,and the energy consumption control of frequency conversion speed regulation device was realized through speed regulation.The influence of speed and frequency on energy consumption of electric traction drum shearer was tested.The results showed that under the vector control scheme,the energy consumption of electric traction drum shearer was the lowest when the traction speed and drum speed were set to 400 r/min and the frequency was 62 Hz.Under the constant pressure control scheme,when the traction speed and drum speed were set at 600 r/min and the frequency was 135 Hz,the energy consumption of the electric traction drum shearer was the lowest.Through the frequency con-version speed regulation of the electric traction drum shearer,the energy consumption of the frequency conversion speed regulation of the electric traction drum shearer was reduced.
