摘要:
高铁通过电分相时,主断路器切断动作会产生牵引变压器过电压,对牵引网及车载设备具有较大危害. 分析了CRH2型动车组过分相时产生过电压的机理,利用SIMULINK建立了动车组牵引传动系统模型,研究了高铁过分相运行状态及电路特性,提出基于RC吸收法治理措施及其优化参数设计. 同时,还研究了合闸电压初相角对过电压的影响,提出了基于自动准同期装置控制合闸相位角的过电压治理方案,为高铁过分相时牵引变压器过电压的抑制提供了理论依据与工程指导.
Abstract:
The overvoltage of the traction transformer is generated due to the cut on or off operation of the main circuit breaker,when high speed train passes the neutral section. It has a great harm on the power systems and other trains. The overvoltage mechanism is analyzed due to CRH2 electric multiple units passing the neutral section. The traction drive system models are established on the basis of SIMULINK for CRH2 electric multiple units. The operation performance and circuit characteristics are studied. The overvoltage treatment scheme is introduced on the basis of the RC absorption and its parameter optimization strategy is proposed. Moreover,the relationship between the voltage phase and overvoltage is analyzed while CRH2 electric multiple units passing the neutral section. The automatic quasi synchronization device is proposed to control the voltage phase and decrease the overvoltage,which provides the theoretical basis and engineering guidance to solve the overvoltage and increases the safety and reliability of high speed train operation.
