THE COMPENSATION OF REACTIVE POWER OF THYRISTOR ELECTRIC DRIVE OF DIRECT CURRENT
Abstract
Purpose of work - to get analytical dependence of capacity of compensating condensers on the angler of control of thyristor, inductance of circle of armeture and current of loading. Research method – the design of processes of indemnification of reactive power on a mathematical mode. It was the getted formula for calculation compensating condensers for the electric drives monophase thyristor rectifier, which calculate capacity through equality of nonsine energies of the magnetic field of finding of armature and electric field of condenser. Conducted computer experiments showed sufficient exactness of calculation values of capacities of compensating condensers with the capacity of condensers certain the method of approximate on a model. As a result of work is shown that the consumption of current from a network is minimum during complete indemnification of reactive power.Keywords: thyristor electric drive, reactive power, compensation
