| Abstract: | At present，the automatic frequency conversion speed regulation method of drilling electrical equipment has the problems of poor reliability and low maintenance performance.Therefore，the automatic frequency conversion speed regulation method of drilling electrical equipment based on PLC was proposed.Based on the characteristic analysis of PLC，the PLC control system was constructed；a doubly fed speed regulating device was set and applied to the PLC control system to adjust the torque of drilling electrical equipment；the PLC control system was optimized into a double closed-loop control system，and the feedforward technology was used to eliminate the static error of drilling electrical equipment caused by frequency conversion speed regulation，so as to realize the automatic frequency conversion speed regulation of drilling electrical equipment.Through the reliability analysis and maintenance performance test of this method，it was verified that this method has higher stability and stronger security. |
