智能变电站长时间运行时,检修人员从保护装置运行信息不能充分了解到保护装置状态,如保护装置的隐性故障,元件老化、元件过热、元件振荡损坏等问题,且通过传统的故障检测、故障分析和故障定位方法对于设备的隐性故障排查不太适用,因此需要配置支持状态监测、状态分析,故障定位的监测系统。传统的状态监测系统使用无线局域网监测单一信号量,多用于一次设备的监测,其存在着信号弱、距离短、布网复杂等弱点,且不支持直接远程查看和综合分析设备状态信息功能。针对上述问题提出基于3G无线通信模式,监测智能设备多个状态指标的系统设计模型及实现方法,达到定位排除隐藏故障,简化用户工作量,提高电网可靠性的目的。
When the intelligent substation runs for a long time, the maintenance personnel can not fully understand the status of the protection device from the operation information of the protection device, such as the hidden fault of the protection device, the aging of the component, the overheating of the component and the damage of the component oscillation, and the traditional fault detection, Analysis and fault location methods are not suitable for hidden troubleshooting of devices. Therefore, you need to configure a monitoring system that supports state monitoring, status analysis, and fault location. The traditional condition monitoring system uses wireless LAN to monitor a single semaphore and is used for primary equipment monitoring. It has some shortcomings such as weak signal, short distance and complex network. It does not support remote remote viewing and comprehensive analysis of equipment status information. Aimed at the above problems, this paper proposes a system design model and its implementation method based on 3G wireless communication mode to monitor multiple status indicators of smart devices, and achieves the goal of locating and eliminating hidden faults, simplifying user workload and improving power grid reliability.
