消弧电抗器自动跟踪的调谐技术

Technology of Automatic Tuning for Arc Extinguishing Reactor

在分析了中性点经消弧电抗器接地配电网现有调谐技术的基础上 ,提出了一种可对此类电网关键参数进行实时测量及对消弧电抗器进行自动调谐的新方法。与目前常用的其他方法相比 ,该方法采用了新的测量和调谐理论 ,不需要借助消弧电抗器调谐机构的操作 ,而能自动测量出电网的脱谐度和对地电容电流 ,准确度高、实时性好、适用范围广 ,为电网在正常运行状态下的自动跟踪补偿和单相接地故障下的紧急保护提供了有效的技术保障。

On the basis of analyzing the tuning technology used at present in distribution network with neutral grounding through arc extinguishing reactor, a new method, which can realize real time measuring to the key parameter of network and automatic tuning for arc extinguishing reactor, was brought out. This scheme, which with high precision, good real time and widely using situation, provides network an effective guarantee for automatic compensation in the time of good running and urgent protection in the time of single phase grounding fault occurring.
