Aiming at the problems existing in the electrical control system of a coal mine hoist using the relay-contactor control method, a modification scheme of the full-control doubly-fed frequency conversion speed regulation system for the hoist is proposed in this paper. The full-control doubly-fed inverter speed regulation system Composition and basic functions, expounds the working principle and characteristics of full-control doubly-fed variable frequency speed control system, and gives the technical indicators and benefits of the hoist after the transformation. Practical application shows that the system is economical, stable, safe and reliable.
