智能变电站物理回路故障诊断方案设计及实现

Design and Realization of Fault Diagnosis Scheme for Physical Circuit of Intelligent Substation

现阶段智能变电站采用光纤通信替代了大量的电缆连接,在发生故障时给运维人员带来许多困难。文章从智能变电站光纤链路告警出发,以变电站的虚实回路映射为基础,通过规范化的链路告警信息,构建智能变电站光纤链路故障诊断方案,该方案从变电站信息传输方式和组网形式进行了综合考虑,并通过实际应用验证了该方案的有效性和实用性,大幅降低了变电站运维人员的工作负担,有效提高了运维工作的可视化水平。

Nowadays, intelligent substation uses optical fiber communication to replace a large number of cable connections, which brings many difficulties to operation and maintenance when the failure of physical circuit occurs. Starting from the optical fiber link alarm, based on the virtual and real loop mapping of the substation, the fault diagnosis scheme of the optical fiber link of the intelligent substation is constructed through the standardized link alarm information. The scheme takes into account both the substation information transmission and networking forms. The effectiveness and practicability of the scheme are validated through practical application, and the working efficiency of the operation and maintenance personnel of substation is improved.
