摘　　要：针对城轨列车在接触网禁停区非预期停车可能导致接触网拉弧断电,继而引发线路停运事故的情况,信号系统根据供电专业的输入信息设置接触网禁停区域,对线路区间和站台不同区域的禁停区实现列车自动防护功能,防止列车在禁停区内停车。阐述在列车自动运行模式和列车自动防护手动驾驶模式下对应的禁停区防护功能;分析增加接触网禁停区防护后,对信号降级模式和高密度运营场景的影响;分别提出司机按辨识禁停标识驾驶和通过ATS的运营调整策略进行修正的应对策略,并进行仿真验证,结果表明折返间隔符合交路要求。接触网禁停区防护功能目前已在上海地铁6号、8号、9号线陆续上线,且运行稳定。For the situation that the unexpected stop of the train in the no-stop zone of the catenary may cause the arcing and power failure,which will then cause the line out of service accident,the signal system sets the catenary no-stop zone according to the input information of the power supply specialty,and realizes the automatic protection function of the train in different areas such as sections and platforms so as to prevent the train from stopping in the no-stop zone.The corresponding protection functions of no-stop zone in the automatic train operation mode and the automatic train protection manual drive mode is elaborated.Though analyzing the impact of increasing catenary no-stop zone on the signal degradation mode and high-density operation scenario,the response strategies are put forward that driving according to the no-stop sign identification and correction through the ATS operation adjustment strategy.The simulation verification results show that the turnback interval meets the requirements of the cross-route.The protection function of catenary no-stop zone has been successively put into service on Shanghai Metro Lines 6,8 and 9,and the operation is stable.
