Simplified method of calculation of parameters of microprocessor defense on increase of current

О. А. Данилов

Abstract


Defense of contact network of direct-current plays a large role providing of reliable work of power supply of railways. New microprocessor defense of feeders of contact network of direct-current plug in itself a few independent defense. For tuning of defense on the increase of current not walked around to define parameters which are independence between itself. Therefore a setpoint for this defense can reach in a few cycles by the selection of coefficients and however in the process of exploitation there is a necessity of further clarification.

The purpose of work consists in determination of necessary parameters for tuning of defense on the increase of current by a simple in practice calculation, but in also time suffices exact. It is routine in the article, that accepting time of measuring of current multiple permanent time of chain of short circuit it is possible to simplify calculations and define all of parameters for tuning of microprocessor defense.
