The Lithium battery energy system used in the rubber-tyred gantry container crane includes controllable or uncontrollable large-power rectifier ( AC/DC) , inverter ( DC/AC) , frequency converter ( AC/AC) , and other non-linear electric and electronic convertor devices.Opening and closing the power switches of these devices can inevitably generate the voltage or current higher harmonics on both primary and secondary sides, providing large magnitude than regular RTG. The paper introduces and analyzes how to effectively suppress harmonics.%轮胎式集装箱门式起重机 ( RTG) 上使用的锂电池能源系统中包括可控或不可控的大功率整流器( AC/DC)、 逆变器 ( DC/AC)、 变频器 ( AC/AC) 等非线性电力电子变流设备, 这些变流设备的功率开关器件的通断不可避免地会在一次侧和二次侧产生电压或电流高次谐波, 且高次谐波的量值要比常规的RTG大. 文中就如何有效抑制谐波进行了分析和介绍.
