城市轨道交通用户是电力系统供电保障的重点,从城市轨道交通用户的供电方式和负荷特性入手,通过确立电力调度与地铁调度协同配合的思路,建立使用冲击负荷性质的N-1运行条件,利用信息化手段监视外电源负荷状况和外电源“评星”定级法评价地铁外电源的安全性等手段,实现了城市轨道交通外电源安全管理质量的提升,在治理城市轨道交通外电源存在的隐患同时,也为重要客户供电保障工作开创了新的模式。
Starting from the power supply mode and load characteristics of urban rail transit users, urban rail transit users are the key points of power system power supply protection. By establishing the coordination between power dispatching and subway dispatching, the N-1 operating conditions using impact load are established. Information means to monitor the external power load conditions and external power “Rating Star ” rating method to evaluate the safety of the external power supply and other means of subway, to achieve the safety of the city rail transit power safety management to enhance the quality of the urban rail transit outside the power The hidden dangers exist at the same time, but also create a new mode for the power supply protection work for important customers.
