摘要
再生制动能量逆变回馈装置能将多余的再生能量回馈交流环网,实现二次利用,同时抑制直流母线电压波动,提高牵引供电质量。通过建立城市轨道交通列车牵引计算和含逆变回馈装置的牵引供电系统模型,开发逆变回馈装置节能计算软件,科学地选择逆变回馈装置的容量和安装位置,实现经济利益的最大化。
Regenerative braking energy inverter feedback device can feed back excess regenerative energy to AC ring network to realize secondary utilization,and at the same time suppress DC bus voltage fluctuation to improve traction power supply quality. Through the establishment of urban rail transit train traction calculation and traction power supply system model with inverter feedback device,the energy-saving calculation software of inverter feedback device is developed to select scientifically the capacity and installation location of inverter feedback device,thus achieving the maximum economic benefits.
