Three-phase voltage unbalance treatment device based on voltage dynamic compensation

The utility model relates to a three-phase voltage unbalance treatment device based on voltage dynamic compensation. By detecting the voltage information of the A phase, the B phase and the C phase, the processor judges that the three-phase voltage difference exceeds a preset value, judges that the three-phase voltage is unbalanced, and performs inter-phase current transfer according to the voltage imbalance condition, so that the aim of balancing the voltage of the tail end mounting point is fulfilled. According to the utility model, no extra current transformer needs to be installed, the problem of dynamic unbalance of the three-phase voltage of a line end installation point in a current power distribution network can be solved, the three-phase voltage of a device installation point is dynamically adjusted under the condition of uninterruptible power, and reliable operation of a load is ensured. 本实用新型涉及一种基于电压动态补偿的三相电压不平衡治理装置。通过检测A相、B相和C相三相的电压信息，处理器判断三相电压差超过预设值，则判断为三相电压不平衡，则处理器根据电压不平衡的情况进行电流的相间转移，达到末端安装点电压平衡
