低压变电站自动化设备入网调试验收方法

Method for Commissioning and Acceptance of Automation Equipment in Low Voltage Substation

为了降低入网调试验收中异常设备定位的误差,提出低压变电站自动化设备入网调试验收方法。建立变电站自动化设备全景数据采集方式,实现对低压变电站的全景数据采集,当采集结果中出现异常数据时,以设备所在线性区域为基础进行故障设备定位,利用检测信号的输出结果调试入网参数,并以二分裂法实现对异常设备的定位。实验结果表明,所提方法能够实现对故障设备的准确定位,在验收工作中具有良好的应用效果。

In order to reduce the positioning error of abnormal equipment in the commissioning and acceptance of network access,this paper puts forward the commissioning and acceptance method of automation equipment in low voltage substation.Establish the panoramic data acquisition mode of substation automation equipment to realize the panoramic data acquisition of low voltage substation.When abnormal data appears in the acquisition results,locate the fault equipment based on the linear area where the equipment is located,debug the network access parameters by using the output results of detection signals,and realize the positioning of abnormal equipment by two splitting method.The experimental results show that the proposed method can accurately locate the faulty equipment and has a good application effect in the acceptance work.
