基于Linux操作系统的变电站集中式保护方案

Study of centralized protection of substation based on Linux operating system

针对传统继电保护装置相互独立、硬件重复配置等缺点,提出了一种基于Linux操作系统的变电站集中式保护系统的硬件构成及软件实现方案.该系统以变电站为保护对象,统一考虑整个变电站的保护功能,可实现信息的共享,有利于提高保护性能,降低变电站运行成本.通过PSCAD建模仿真及实验测试,验证了方案的合理性与可行性.

Considering the traditional protective relaying device′s disadvantages such as the independence from each other and the repeat of hardware configuration,a substation centralized protection scheme which based on Linux operating system is proposed in this paper.Centralized protective system is one kind of defensive function which takes transformer substation as the protected object and takes the whole transformer substation into unified consideration.It can achieve the sharing of information,improve the protective performance and decrease the running cost of substation.The hard-ware constitution and software implementation scheme is also provided,and the rationality and feasibility of the substation centralized protection scheme has been proved through the PSCAD modeling simulation and experiment.
