摘要
提高自动补偿装置效率,处理好谐波增大等问题,可以提高配电网的稳定性,为此,设计了一种新型自动补偿装置。该装置由两部分组成,首先通过并联电抗器补偿线路中的电容性电流,维持感性无功功率和容性无功功率的平衡关系,然后由网格化自动补偿器对配电网的输入电流进行频谱生成并对频谱进行分析计算,根据不同的故障类型选择不同的处理方式,以最快速度解决问题,降低供电变压器及输送线路的损耗,提高供电效率,最终实现配电网感性负荷的自动补偿。为检测装置的运行效果,与传统补偿装置进行对比实验,结果表明,基于网格化的配电网感性负荷自动补偿装置可以在短时间内对感性负荷进行自动补偿,提高配电网的稳定性,减少不必要的电能浪费,节约资源。
To improve the efficiency of the automatic compensation device and deal with the problem of increasing harmonics can improve the stability of the distribution network.Therefore,a new type of automatic compensation device is designed in this paper.The device is composed of two parts.First,through the shunt reactor to compensate the capacitive current in the line,the balance between the inductive reactive power and the capacitive reactive power is maintained.Then,the grid automatic compensator generate the frequency spectrum of the input current of the distribution network and the frequency spectrum is analyzed.According to different fault types,different processing methods are selected to solve the problem at the fastest speed to reduce the loss of power supply transformer and transmission line,improve the efficiency of power supply,and finally the automatic compensation of inductive load of distribution network is realized.In order to test the operation effect of the device,the comparison experiment with the traditional compensation device shows that the grid based automatic compensation device can automatically compensate the inductive load in a short time,improve the stability of the distribution network,reduce unnecessary power waste and save resources.
