配电系统自动跟踪补偿装置的研究

研究了采用高漏抗变压器型可控电抗器作为新型的配电系统自动调整消弧线圈的自动跟踪补偿装置的问题。该装置的控制采用动态补偿方案,实时监测电网电容电流。在正常工作时,补偿装置远离谐振点,当发生瞬时性单相接地故障时,补偿装置实现快速补偿。仿真结果表明:以该原理构成的自动跟踪补偿装置具有伏安特性线性度优良、响应速度快、补偿效果好、对系统适应性强、经济性能指标良好等优点。

The Research of Automatic Tracking Compensation Device of Distribution System

Using controlled reactor of transformer type with high leakage reactance as new automatic tracking compensation device of distribution system was studied in the paper,which could automatically adjust arc suppression coil.The device's control adopted the scheme of dynamic compensation,which could monitor the capacitive current of power net in real time.In normal working,the device was far from the resonance point.When the fault of instantaneous single-phase grounding happened,the device could compensate(quickly.) The result of simulation showed that the automatic tracking compensation device hadsome advantages such as good linearity of voltage-current characteristic,quick response speed,good compensation effect,strong adaptability,good performance index,etc.
