ELECTRIC CIRCUITS CONTROL METHOD FOR DIRECT- AND ALTERNATING-CURRENT LOCOMOTIVES Russian patent published in 2015 - IPC B61L23/00 

FIELD: electricity.

SUBSTANCE: invention may be used for different direct- and alternating-current locomotives. In the method function of additional types of rolling stock adding and deletion is implemented in order to optimise diagnosing process. The approach based on safe operation depending on technical state is used as the method base concept; according to this approach technical state of an object is assessed against maintenance factors ensuring its reliable and safe operation in compliance with standard and regulatory and/or designer (project) documentation and remaining life is assessed against the essential maintenance factors. Factors which change (separately or in some aggregation) may lead to inoperative or faulty state are considered as essential maintenance factors. Depending on complexity degree assessment of technical state may be performed for an object against one or several test parameters. When values of test parameters cannot be measured directly, then they may be determined by processing of other parameters related to the unknown value by well-known functional relations.

EFFECT: increased efficiency of the method.
