摘要
通过对城市轨道交通系统、铁道电气化系统中保护系统遵循的原则进行分析,得出传统保护较难解决选择性和速动性之间的矛盾,提出将变电所间有关综合保护测控一体化装置进行联网,利用保护测控装置之间的信息资源共享和光纤网络通信的快速响应性的优势,将保护的采样信息或保护动作信息在有关保护装置之间进行传输,并通过可编程功能参与保护动作判据,从而克服选择性与速动性之间的矛盾。
This article firstly analyzes the principles followed by the protection systems of the urban railway transportation system and the railway electrification system and draws the conclusion that the contradiction between selectivity and quickacting is difficult to be solved in traditional protection. Then this paper puts forward the network connection scheme for connecting the integrated protection and supervising devices of related substations, making use of the advantage of information resource sharing among the protection devices and rapid responsivity of the fiber network communication and transmiting sampling and operation information among the protection devices. The contradiction between selectivity and quickactins is solved consequently.
