摘要
提出了谐振接地电网脱谐度的外加扫频信号自动测量法 ,可将测量误差控制在0 5 6%以下 ,测量时间不长于 2 0s.在准确测量的基础上 ,又直接以脱谐度为被控量 ,设计了消弧线圈的自动跟踪调谐方案 ,安全可靠 .同时设计了可完成调谐过程的模糊控制器 ,实时性好 ,控制规则通用性强 ,所需设备甚少 。
The measuring method of turn off degree of resonance grounding net is presented through measuring resonance frequency, Which reduces the error to 0 56% and shorts the measuring time to 20 s.In addition, the scheme of automatic tracking regulation of petersen coil is advanced.The fuzzy controller for regulation is designed very well that has importantly practical significance.
