The active resistance of the overhead contact line of public electric transport, such as trolleybus, causes a voltage drop which must be compensated by taking a stronger current from the substation to provide the necessary power to maintain a certain speed of motion. Moreover, this resistance is variable because the distance between the moving trolleybus and the substation changes. The paper describes the calculation of the overhead catenary resistance for the situation when only one trolleybus moves in a catenary stage and for the situation when two trolleybuses move in a common catenary stage. A method for virtual real-time simulation of catenary power transmission using voltage source elements was developed and described.
