摘要
在现有城市轨道交通供电系统的基础上,构建能馈式牵引供电系统的方案,从根本上改善传统牵引供电系统能量的单向流动性引起的系列问题,解决再生制动能量的回馈与利用。以概率论理论为基础提出了一套确定PWM(脉宽调制)整流器容量的计算方法。
It is an important measure to utilize the regener- ative braking energyfor the goal of energy saving. At pres- ent the multi-pulse diode rectifier is widely used in traction power system all over the world, but the one-way energy transmission from AC to DCcannot recycle effectively the regenerative braking energy when a train brakes frequent- ly. In this paper, based on the existing traction power sys- tem, the development ofan energy-fed traction power sys- tem is proposed. Furthermore, a series of computing method is used to calculate the capacity of PWM rectifier, which presents a certain guiding significance to the design and in- stallation of the new system.
