自动调谐式消弧线圈控制策略研究

Research on Automatic Tuning Arc Suppression Coil Control Strategy

在分析一种新型自动调谐式消弧线圈工作特性的基础上,提出了新型主、次调联合控制策略并分析了一种既适合单台消弧线圈单机运行又适合多台消弧线圈同网并联运行的调谐测量方法。最后采用基于NuMicro M051^(TM)的控制器结构,在实验室模拟1.2 kV电网进行实验,实验结果证实了所提主、次调联合控制策略及调谐测量方法的正确性。

Based on the analysis of the characteristics of a new type of automatic tuning arc suppression coil, com- bined control strategy on major and minor adjustment is proposed.And the tuning method of measurement which is suitable for both single coil single operation and a plurality of arc suppression coil multiple operation tuning method of measurement is analyzed.Finally, based on the structure of NuMicro M051TM controller, an experiment is conducted in the laboratory which mimics the 1.2 kV power grid.Experimental results confirm the proposed combined control strate-gy on major and minor adjustment and the correctness of the tuning method of measurement.
