Abstract
Description
技术领域technical field
本发明涉及电网技术领域，更具体地，涉及一种用于电网设备复电时检测信号的系统。The invention relates to the technical field of power grids, and more specifically, to a system for detecting signals when power grid equipment is restored.
背景技术Background technique
地方电网规模和设备数量不断扩大，基建、技改、电网设备检修任务繁多，随之产生的检修异常信号也越来越多。当检修中的设备需要复电时，如果能量管理系统告警窗上还存在设备相关的异常信号尚未复归，如线路保护装置异常，开关控制回路断线等，会影响设备复电时的安全性，有可能造成设备在送电过程中跳闸甚至引发更严重的后果，危及电力系统的稳定性。The scale of local power grids and the number of equipment continue to expand, and there are many tasks in infrastructure construction, technical transformation, and power grid equipment maintenance, resulting in more and more abnormal maintenance signals. When the equipment under maintenance needs to be restored to power, if there are still equipment-related abnormal signals on the alarm window of the energy management system that have not been reset, such as abnormality of the line protection device, disconnection of the switch control circuit, etc., it will affect the safety of the equipment when it is restored to power. It may cause equipment to trip during power transmission or even cause more serious consequences, endangering the stability of the power system.
传统的方法是在某设备复电前，通过电力调度员人工去查看能量管理系统告警窗是否存在该设备的相关未复归信号，并由调度员去判断未复归的信号是否影响设备复电。若是影响设备复电安全性的信号，如线路保护装置异常，开关控制回路断线，母差保护装置异常等，必须复归信号后才允许对设备送电。有些线路涉及好几侧的变电站端，线路送电前每一侧变电站的信号都要核查。一旦调度员疏忽大意，复电前没有核查信号或者遗留某一侧变电站的信号没进行核查，将增加设备复电时跳闸的隐患，依靠人工核查不能做到万无一失。The traditional method is to use the power dispatcher to manually check whether there is a relevant unrecovered signal of the equipment in the alarm window of the energy management system before a certain equipment is restored to power, and the dispatcher judges whether the unrecovered signal affects the restoration of the equipment. If there is a signal that affects the safety of equipment restoration, such as abnormality of the line protection device, disconnection of the switch control circuit, abnormality of the busbar protection device, etc., the power supply to the equipment must be restored after the signal is reset. Some lines involve substations on several sides, and the signals of the substations on each side must be checked before the line is powered. Once the dispatcher is negligent and fails to check the signal before power is restored or the signal of a certain side of the substation is not checked, it will increase the hidden danger of tripping when the power is restored, and relying on manual verification cannot be foolproof.
