摘要
针对电力机车运行产生的高次谐波诱发的车网谐振问题,本研究开展了地面与车载谐波检测技术研究。基于对测试数据的深入分析,制定了有效的抑制策略,以改善高次谐波对机车高压部件的不利影响。在此基础上,进一步提出了电力机车谐波源头治理、供电方案优化及联合分析机制建立等方面的建议,为保障电力机车的安全稳定运行提供理论支撑与技术保障。
This study conducted research on ground and onboard harmonic detection technology to address the problem of vehicle network resonance induced by high-order harmonics generated during the operation of electric locomotives.Based on in-depth analysis of test data,effective suppression strategies have been developed to improve the adverse effects of high-order harmonics on locomotive high-voltage components.On this basis,further suggestions were put forward for the control of harmonic sources in electric locomotives,optimization of power supply schemes,and establishment of joint analysis mechanisms,providing theoretical and technical support for ensuring the safe and stable operation of electric locomotives.
