摘要
小电流接地选线技术发展多年,取得了一定的效果。虽然选线技术对电力系统有着重要的作用,但由于技术原因和管理原因的责任不明确,造成了实际运行效果并不理想。为了解决这个问题,进行管理创新,提出了为选线建立故障诊断系统的思想,利用先进的通讯手段,对安装于现场的选线装置进行管理监控,并从离线诊断和在线诊断两方面描述了该系统的作用,同时用现场实际数据加以验证,解决了长期在选线失败原因上的迷惑,取得了很好的效果,证明故障诊断系统的建立对完善管理机制、进一步发展选线技术具有重要的意义。
The fault line detection in neutral point non-effectively grounded-system has obtained certain effects with the development of many years. The fault line detection is not very effective because of the ambiguous reasons of the techniques and managements though it is very important for power system. For solving this problem and management innovation, this paper proposes an idea of setting up system of fault detection for line selection, monitoring and controlling the devices on-site with correspondence and network. And the functions of the system is described on off-llne and on-line condition. The effect is satisfactory on the verification of the recorded data on-site and the reason of fault detecting is found. The result shows that establishing the system of fault detection is very important for perfecting management and advancing the technique of line selection.
