中文摘要:
      当整流电路所带负载为蓄电池时,其电路工作情况和无功功率计量均与纯阻负载有所不同。该文提出一种单相相控整流电路带反电势负载的无功功率图解法,通过网侧电压、电流和对应磁通波形绘制三维Lissajous图形,并利用其投影三角形的面积来分析无功能量流,该方法可为单相相控整流电路的无功功率测算及功率补偿提供参考。分析结果表明,该文所提反电势负载的无功功率图解法简单直观,且有较好的实时性。
英文摘要:
      When the load of the rectifier circuit is the armature of the battery, its circuit operation and reactive power measurement are different from pure resistance load. In this paper, a method of reactive power diagram with back EMF load is proposed in this paper. The three-dimensional Lissajous diagram is drawn by the voltage, current and corresponding flux waveform of the network side, and the area of the projection triangle is used to analyze the non functional flow. This method can be used to measure the reactive power and compensate the power of the single-phase phase controlled rectifier circuit. It provides reference. The analysis results show that the reactive power diagram method proposed in this paper is simple and intuitive, and has good real-time performance.
