Abstract
A big percent of false actuations of relay protection devices is connected not only with emergency operation modes of a traction power supply system, but also with starting and transient currents flowing in the catenary at movement of heavy-loaded trains, united freight trains, at realization of batch schedule, movement of trains on difficult grading of track and also at the application of recuperation mode by currently used locomotives. The study shows that it is possible to decrease the number of actuations of relay protection devices in described cases by the application of alternative method of analytical presentation of measured signals and the forecasting of dynamics of measurement of starting and transient currents flowing in the catenary.
