采样接收软压板误操作的影响分析

Impact Analysis of Sampling Receiving Soft Jumps Misoperation

采样接收软压板的误投退会引起保护装置的告警或者误动作。针对目前SV软压板误投退的情况,利用智能变电站实训室进行实验,结合实验录波数据,分析了母线保护装置在间隔采样接收软压板误退出时的动作情况,并对六统一及新六统一的不同装置所展现的不同点做了比较说明,有助于现场运维人员掌握母线保护装置采样接收软压板所具备的功能,规范采样接收软压板的操作流程。

The misdirected back of sampling receiving soft jumps will cause the alarm or mistaken action of the protection device.In allusion to the situation of current SV soft jumps misdirected back, the training room in intelligent substation was used to carry out experiments. Combining with the recording data of the experiments, this paper analyzed the action situation of busbar protection device when the interval sampling receiving soft jumps quitted and compared the differences between the old and the new six-unified devices, which is helpful for operators to master the functions of sampling receiving soft jumps in bus protection device, so as to standardize the operation procedure of sampling receiving soft jumps.
