| Abstract: | In pulp and paper industry once the paper making process ends at the point of reeling the paper in jumbo reels, its mainly necessary to convert the end product to a useful finishing product so that it can be utilized. For that the foremost step is to slit and rewind the paper in the core with specified needed sizes. The unit that performs the above process is REWINDER, which consists of a unwind stand where the jumbo paper reels are transported using the overhead cranes from the paper machine. Usually, a motor with the capacity of around 625kW is used to drive that unwind stand from where the paper is pulled to the next stage of slitting. Initially during the starting of the process the paper is pulled with the limited tension and once the necessary tension value is reached, the paper is pulled with full tension leads to the increase in the speed of the motor over the synchronous speed. Once the motor crosses the synchronous speed Ns its starts to regenerate the power working as a generator. The same all above the energy retrieving process can be held in EOT cranes during deaccelerating by in name of Regenerative Braking. Using the four-quadrant medium voltage converter, the induction motor can work as a generator at the optimum working efficiency all along, and the surge occurred at the transit from motor mode to generator mode of the motor can be avoided at the same time. In the paper, the topology of four-quadrant medium voltage converter and the working principle of motor in Rewinder and in EOT cranes at generator mode via using the converter are proposed and analyzed |
