Research on Operation Control System for High Speed Maglev with Long Stator and Normal Conducting

目前我国既有的高速磁浮运行控制系统已不能满足长距离干线复杂运营的需求。为此,文章以实现长大干线自动追踪运行、满足长途多分区环境、适应复杂地理气候条件的列车安全运营为目标,通过研究磁浮系统运营场景并识别安全隐患,开发了一套适应我国复杂应用环境的常导长定子高速磁浮运行控制系统,其采用中车自主研发的安全计算机平台,实现了高速磁浮列车速度曲线监控、列车自动运行、列车防护、牵引切断、道岔防护和进路防护等功能。在实验室,半实物仿真集成测试用例645个,通过率为89%;在试验线现场,试验用例59个,受条件限制未执行用例2个,通过率达97%。实验结果表明,文章所设计的高速磁浮运行控制系统接口和功能完整,可满足600 km/h磁浮列车的控制需求。

In view of the problem that the existing high speed maglev operation control system in China can not meet the complex operation requirements of long-distance trunk lines, this paper aims at automatic tracking operation of long-distance trunk lines, meeting long-distance multi-zone environment and adapting to safe operation of trains under complex geographical and climatic conditions. By studying operation scenarios of maglev system and identifying potential safety hazards, a set of high speed maglev operation control system with long stator is developed to adapt to the complex application environment in China, which adopts the independent and controllable safety computer platform of CRRC, realizes functions of high speed maglev train speed curve monitoring, automatic train operation, train protection, traction cut-off, turnout protection and route protection. There are 645 integrated test cases through laboratory hardware-in-loop simulation, with a pass rate of 89%;59 field test cases on the test line, and 2 cases not executed due to the conditions, with a pass rate of 97%. The results show that the operation control system designed in this paper has complete interfaces and functions, and can meet the control requirements of 600 km/h maglev train.
