Design for Extension Supply Contactor control of train with multiple Auxiliary Power Generator

다중 전원장치를 갖는 차량의 연장급전 제어방안

These days customers require various things such as multiple train, variable trainset, multiple Auxiliary Power Generator(APG) and so on. Among these, the train with multiple APG is installed with APG in each car. Thus, we control and monitor train installed with multiple APG through the TCMS(Train Control & Monitoring System). The TCMS supervise APG failure status and transmit control data in case of a APG failure or more, so energize or de-energize ESK and LRR. Therefore, we can easily control ESK and LRR which gets hard to control because of multiple APG.
