Application and analysis of energy dispatching device in electrified railways

双碳目标下,实现电气化铁路节能减排和绿色发展至关重要,回收利用列车的再生制动能量是节能降耗的重要手段。根据牵引变电所的能量调度原理,建立含能量调度装置(energy dispatching equipment,EDE)的牵引供电系统数学模型,分析不同工况下能量调度装置在铁路牵引供电系统的调度策略。通过示例分析,基于能量调度装置的调度策略能有效降低牵引变压器的容量,减少运营商的需量电费和计量电费,降低运营商成本,提高能量利用率。

Under the dual carbon target,it is crucial to achiev energy-saving,emission reduction,and green development of electrified railways.Recycling and utilizing the regenerative braking energy of trains is an important means of energy conservation and consumption reduction.Based on the energy scheduling principle of traction substations,a mathematical model of traction power supply system with energy dispatch equipment(EDE)is established,and the scheduling strategies of energy dispatch equipment in railway traction power supply system under different working conditions are analyzed.Through example analysis,the scheduling strategy based on energy scheduling devices can effectively reduce the capacity of traction transformers,reduce the demand for electricity and metering electricity fees of operators,reduce operator costs,and improve energy utilization efficiency.
