Downward Belt Conveyer Case - INVT Goodrive3000 Series Inverter

The application of Goodrive3000 on downward belt conveyer, successfully solved the problem of regeneration of fed back power.

Due to different geological conditions of coal mine, the belt conveyer has lane transport, upward and downward. Due to the gravity of the material and belt, during downward working, the mechanical energy is converted into electrical energy and fed back to the motor and drives. If some of this energy is regenerated to power grid, the coal mine energy saving will be very beneficial.

Different to lane transport and upward, the variable frequency inverter of downward belt conveyer, not only need to solve the power balance of multi motors, but also need to control the fed back energy. This paper describes INVT Goodrive3000 (referred to as GD3000) four-quadrant inverter in Shanxi, a coal mine site applications.

It is a downward belt conveyer with big angle, it needs four-quadrant inverter, we choose 2 pieces of GD3000-11-400G-12 with explosion-proof shell. Two inverters use master-slave control, to make sure the two motors work at same speed and same power. And they can regenerate the power to grid.

......

The application of Goodrive3000 on downward belt conveyer, successfully solved the problem of regeneration of fed back power. It has a very active role for the coal mine automation upgrade and energy saving, it is worth promoting. INVT is committed to the mining enterprises of automation and energy efficiency control to provide a complete solution!
