摘  要:现阶段电力系统保护定值需手动录入保护装置,出错风险高,而定值巡检需人工现场逐一核对,效率低下。鉴于此,本文研究了定值在线巡检若干关键技术,包括在线巡检系统与定值单系统接口设计、定值跨安全区流动、设备及保护智能关联、定值自动比对等,并在此基础上研发了继电保护定值在线巡检系统,从而实现了运行定值与下发定值的智能核对,大大提高了定值巡检效率。目前,该系统已在广西220 kV及以上电压等级电网试用,成效初显,其有效弥补了定值闭环管控的短板。At current stage,the relay protection setting values of the power system needs to be manually entered into the protection device,which has high error risk.And the inspection of setting values requires manual field verification one by one,which has low efficiency.Therefore,several key technologies of setting value online inspection are studied in this paper,including the interface design between the online inspection system and the setting value list system,the setting value flow crossing different security zones,the intelligent association of equipment and protection and the automatic setting value comparison and so on.On this basis,the relay protection setting value online inspection system is developed to realize the intelligent verification between the operation setting values and the official setting values,which greatly improves the efficiency of setting value inspection.At present,the system has been on trial at 220 kV and above voltage level power grids in Guangxi,and the early results have been shown.It has effectively made up for the shortcomings of setting value closed-loop management and control.
