  1. Dynamic voltage restorer ( dvr ) is an important member of custom power family. it can compensate voltage harmonic, fliker, sag, swell, unbalance, and has the advantage of high performance / price, so it is necessary to investigate the theory and operation of dvr

    動態電壓恢復器（ dynamicvoltagerestorer ? dvr ）是custompower家族的一個重要成員，它可以補償電壓的跌落、突升以及諧波，具有高性價比的優點。
  2. Moreover, owing to rapid use of large numbers of nonlinear or impactive loads in power system, many power quality problems will be caused, such as voltage sag, swell, unsymmetry, flicker, fluctuation, harmonic and so on

    然而，隨著電網中沖擊性、非線性負荷的不斷增加，導致電網電壓波形發生畸變、波動、閃變和三相不平衡等電能質量問題卻越來越嚴重。
  3. The method has perfect effect on calculating the voltage swell and sag, voltage notch and frequency deviation. numerous simulations also prove the effectiveness of the method

    對于電壓驟升驟降、電壓缺口以及頻率偏移，該計算方法也有很好的效果，大量的模擬結果證明了這一點。
