地铁列车无电区微制动技术的研究与应用

Study and Application of Adaptive Micro-brake Technology When Metros Passing No-electricity Areas

详细分析了地铁车辆过无电区时电源中断及中间电压变化情况,提出了自适应微制动维持中间直流电压稳定的技术,并确定了相应的工程应用解决方案,且通过试验验证了技术方案的有效性与实用性。试验结果表明:采用该技术的国产地铁满足国内外客户的要求,该技术达到了同行业的先进水平。

Power interruption and intermediate DC link voltage variation were analyzed in detail when metros passing no-electricity areas, and adaptive micro-brake technique for keeping the intermediate DC voltage steady were put forward. Corresponding application solutions was provided, effectivity and practicability of which was validated by experimental verification. The experimental results showed that the adaptive micro-brake technique met the requirements of domestic and foreign customers, and reached advanced level in the same industry.
