INCREASE ENERGY EFFICIENCY DRIVEN VERTICAL-AXIS BLADE WINDTURBINE

Abstract

Systems of forced cooling of large power electrical machines - motors and generators using industrial
fans, is widely extend in such industrial applications as hot rolling mills and cold rolling mills, mine elevating
machines. Lack of automated control systems of fans electric drives leads to significant cost overruns electricity,
particularly in the case of cyclic loading cooled electrical machines.
Described in the article of the automated control system of electric cooling fans of powerful electric motors for
mine hoists can significantly reduce the power consumption of the said electric.
This automatic control system built using frequency converters for speed control of fans electric motors and
control of programmable controllers. Control algorithm implemented in software controller determines the required
number entered fans and their speed of rotation, providing a minimum energy consumption fan motors to maintain the
desired temperature motors mine hoists when they work cyclic.
