Research of variable frequency control technology for heavy adjustor in power plant fuel system

Traditional run way of the heavy adjustor in thermal power plant fuel system and its creation to influence badly is carefully investigated Based on run characteristics of heavy adjustor, technology scheme that traditional run mode is improved by PLC as central controller and variable frequency control technology is deeply studied, variable frequency control system and electricity reformation circuit is designed, a principle of choosing converter is analyzed .Actual operation of variable frequency control system proves: the problem that high inertia, great torque load is started and multiple motors are synchrodrived is solved So the system running condition is improved, vibration and impact is greatly reduced when heavy adjustor approaches carriage, tows carriage and stops, electric energy is saved, mechanic equipment is protected, there is engineering applied value.
