Abstract

The method of setting the decisive parameters is carried out by a calculation. In the first step during the unoccupied state (VS) of the track circuit (KO) all of the track circuit's (KO) considered combinations of discrete values (H) of power supply end equipment setting elements (NPN) and receiver end equipment setting elements (NPP), are set after the chosen steps (ZK), to find the optimum phase angle (αo), between the track voltage (UK), which is induced from the power supply track voltage (NUK), and between the reference voltage (UR) for the unoccupied state (VS) of the track circuit (KO). The state of emergency (HS) and shunt state (SS) of the track circuit (KO) is calculated for this optimum phase angle (αo). In the second step, the track circuit's (KO) power supply end equipment setting elements (NPN) and receiver end equipment setting elements (NPP), are corrected, according to the considered combination of power supply end equipment setting elements (NPN) and receiver end equipment setting elements (NPP). The goal is to find the track circuit's (KO) resultant phase angle (αv). Thus, the first set of values for the optimum configuration (NPNO) of the power supply end (NK) equipment setting elements (NPN) and the second set of values for the optimum configuration (NPPO) of the receiver end (PK) equipment setting elements (NPP) of the track circuit (KO), are determined, until finding the most favourable mutual conditions, for the track circuit's (KO) shunt state (SS) and simultaneously the state of emergency (HS). The lowest possible track voltage during a state of emergency (UKH) is subsequently chosen so, that the lowest possible corresponding track voltage level in the shunt state (UKS) is found. The resulting value (VHN) of the power supply end setting elements and the resulting value (VHP) of the receiver end setting elements found in this manner, are fast set, for the track circuit's (KO) value of the power supply end (NK) equipment and value of the receiver end (PK) equipment found in this manner, and thereby also the resulting phase angle (αv) between the track circuits (KO) track voltage (UK) and between reference voltage (UR) found in this manner.
