A MEASURING METHOD OF DIRECT-AXIS SYNCHRONOUS INDUCTIVE REACTANCE OF A SYNCHRONOUS MACHINE

摘要

Invention belongs to the field of electromechanical devices and may be used in the production and operation of the synchronous machines for determining their electromagnetic parameters. Mode for determining the inductive longitudinal resistance of the synchronous machines is new for it determines the mean of the resistance by the proportion of the voltages and respective currents. For measurement inductive longitudinal resistance it is needed to measure the voltage of the phase U, current I, electromotive power E, angle of the power factor φ angle among the current and the electromotive power ψ and the active resistance R as the curls temperatures function. Longitudinal resistance X(d) is calculated by the formula:The dependency of the inductive synchronous longitudinal resistance from the machine's magnetisation is calculated by changing the mean of electromotive power E.
