电力设备的运行状况对电力系统有着重大意义,耦合电流脉冲信号是表示电力设备运行状况的一个重要参考量,通过实时监测耦合电流脉冲信号可有效防止事故的发生。针对不同设备的定期检修周期不同,从而造成设备欠检修和过检修的情况,开展了合电流脉冲信号无线通信组网监测系统的研究。利用罗氏线圈实时检测到耦合电流脉冲信号,再通过无线传输方式传输至局部放电监测设备,实时反映设备状态。完成了对耦合电流脉冲信号的采集方法,可在不停电的情况下采集相关数据;以无线传输的数据输送方式,将所检测到的数据及时发送至监测仪器中,做到实时监测设备状态;通过将RESTful API寄宿在系统展示层UI界面的后台代码隐藏类文件中,阻止未经授权的访问和数据泄露,保障传输数据安全。满足对电力设备的在线监测要求,在不停电状态下对设备进行健康度辨识与判断,提高了电力设备和电网运行安全性以及供电可靠性。

The operation status of power equipment is of great significance to the power system.The coupled current pulse signal is an important reference quantity to indicate the operation status of power equipment.The occurrence of accidents can be effectively prevented by monitoring the coupled current pulse signal in real time.Aiming at the different periodic maintenance cycles of different equipment,resulting in under-maintenance and over-maintenance of equipment,the research on wireless communication network monitoring system of combined current pulse signal is carried out.The Rogowski coil is used to detect the coupled current pulse signal in real time,and then transmitte to the partial discharge monitoring equipment through wireless transmission to reflect the status of the equipment in real time.The acquisition method of coupled current pulse signal is completed,which can collect relevant data without power failure.The data transmission method sends the detected data to the monitoring instrument in time by means of wireless transmission,so as to monitor the status of the equipment in real time.Data security transmission guarantee means to prevent unauthorized access and data leakage by hosting RESTful API in the background code hidden class file of the UI interface of the system display layer.So as to meet the on-line monitoring of power equipment,identify and judge the health of the equipment without power outage,and improve the safety of power equipment and power grid operation and power supply reliability.
