- Abstract
The CBTC system is usually used in the urban rail transit system with DC power supply. For the intercity railway and urban railway using the CBTC train control system and the AC power supply system, it is urgent to conduct qualitative and quantitative research on the impact of the catenary power phase separation area on the tracking interval time. analyzes the calculation method of tracking interval time for the interval and the vicinity of the station, builds the calculation model of tracking interval time, and analyzes the main factors affecting the tracking interval are the tracking distance and tracking speed; on this basis, in order to prevent the CBTC system from moving The authorized position falls into the phase-separated area, which leads to the accident of phase-drop. The setting method of the phaseseparated protection area is proposed and the conversion principle of the mobile authorization in the phase-separated protection area is analyzed. The tracking interval time of the system after the introduction of the phase-separated protection area is analyzed in detail. The influence principle of the tracking interval time was revised, and the tracking interval time calculation model of the electrical phase-separated area was established. Some suggestions on the setting of electrical phase separation are put forward. Taking the Shenzhen-Huizhou Intercity Dapeng Branch Intercity Railway as an example, the tracking interval time calculation model of the electrical phase separation area combined with the traction calculation software is used to track the interval tracking interval time and station interval of the phase separation area. The time is calculated, and the results show that after setting the Split-phase protection zone, the system tracking interval in this area is all less than 2 minutes, which can achieve the established goal of the train tracking interval being less than 2.5 minutes and meet the system design capability requirements.
