摘要
在电力系统中,某一环节的变电设备一旦出现故障且未及时检修,就会对整个电力系统运行造成严重影响。由于人工巡检难以做到实时监测,设备状态频发事件时有发生,亟须一种手段能够对这类变电设备的运行进行实时监测,同时根据变电设备的实时状态变化对变电设备可能出现的故障进行分类预警。通过实验证明了可听声局部放电模型的可行性。以该模型为基础,设计和开发了软硬一体的变电设备健康状态监测系统。该系统能够实时监测变电设备的运行状态,并通过设备的状态变化及时作出相应的故障判断与预警。该系统的成功研制对提升电力系统的设备监测效率、降低人力成本与运维成本、提高经济效益具有一定的参考价值。
In the power system,once a substation equipment in a certain link malfunctions and is repaired untime-ly,which would cause serious impact to the operation of the entire power system.Due to the dfficulty of manual inspec-tion in achieving real-time monitoring,frequent incidents of equipment status occur.A mean of real-time monitor is nec-essary for such substation equipment,which can classify and predict the possible faults of substation equipment according to the real-time status changes at the same time.The feasibility of the audible partial discharge model has been demon-strated by the experiments.Based on this model,a software and hardware integrated health monitoring system for substa-tion equipment is designed and developed.The system can monitor the operating status of substation equipment in real time and make corresponding fault judgments and warnings in a timely manner based on the changes in equipment status.The successful development of this system has certain reference value for improving the equipment monitoring efficiency of the power system,reducing labor and operation costs,and improving economic benefits.
