| Popis: | This work presents the study of the voltage levels of the DC bus that allow the integration of DC grid applied to industry. Different a traditional microgrid, where voltages have fixed values, this paper will address the voltage variations that the industry's DC bus may suffer due to high energy recovery in a short time. Will be discussed an industry DC bus used to supply a group of induction motors, synchronous permanent magnet motors (SPMM) and the recovery of break energy with a supercapacitor energy recovery system. With the utilization of supercapacitor recovery systems, new industry standards should be adopted and bidirectional rectifiers could be left aside once the break energy recovered will be stored and used to a new machine restart. Moreover, bidirectional rectifiers for high current has critical response for motor's break energy recover and they are expensive and if compared to traditional high current rectifiers. |
