Compensation of reactive power in the power-supplying system in a roller mixer in laboratory conditions
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
Of particular importance are instantaneous voltage and current levels registered in the three-phase power-supplying systems in roller mixer in laboratory conditions. Recorded data allow the apparent power, active and reactive power to be determined as well as power factors cosφ and tgφ for the predetermined parameters of the system sand being mixed and for the given roller sets. On the basis of the registered power fluctuations, the capacity of batteries and condensers compensating the reactive power for the mixer are found. Conclusions are drawn as to technical and economic aspects of the applied compensation strategy.
