用于变电站就地化保护闭环测试和设备管理的智能化平台

An intelligent platform for closed loop test and equipment management of on-site protection devices in a substation

针对变电站就地化保护装置的工作方式和运维模式,提出一种新的闭环测试和设备管理智能化平台。所提智能化平台有效地避免了传统闭环测试模式的繁琐流程,解决了就地化保护装置的设备管理难题。智能化平台包含三项关键技术:信息获取与展示方法、就地化元件保护子机间的环网通信规范和自动测试流程的智能化实现技术。所提智能化平台已经在宁夏石嘴山供电公司长期使用,运行稳定可靠、效果显著。应用结果表明,所提平台保证了就地化保护装置闭环测试的质量,大大减轻了运维人员工作负荷,有效降低了运维成本。

Considering the operational condition and maintenance mode of an on-site protection device in a substation,a novel closed-loop test and equipment management intelligent platform is proposed.The proposed intelligent platform effectively avoids the tedious process of the traditional closed-loop test mode,and solves the equipment management problem of the on-site protection device.The platform includes three key aspects:an information acquisition and display method,a ring network communication criterion among on-site protection sub systems,and an intelligent implementation technology of an automatic test process.The proposed intelligent platform has been used in Ningxia Shizuishan Power Supply Company for a long time,with stable and reliable operation and remarkable effect.The application results show that the proposed platform ensures the quality of the closed-loop test of the on-site protection device,greatly reduces the workload of the operation and maintenance personnel,and effectively reduces the operational and maintenance cost.
