摘要
阐述动态无功补偿装置的原理及接线方式,主要研究电器的投切开关及装置的投切判据。利用复合开关实现电容器组的自动投切,在控制策略上采用了电压无功复合投切判据,有效地克服投切振荡或补偿不充分的缺点,兼顾了降低功率损耗与改善电压质量的作用。该装置能够实现无功功率的快速、准确补偿,且成本较低,在低压电网中具有较好的实用性。
The paper discussed the mechanism and wiring manner of dynamic reactive compensation device, mainly studying the switching breaker of the apparatus and switching criterion of the device. Using complex switch implements the automatic switching of capacitor sets, applying voltage reactive complex switching criterion can effectively avoid such shortcoming as switching oscillation and incomplete compensation with advantages of lowering power consumption and improving voltage quality. The device can quickly, well and truly compensate the reactive power with lower costs, which can be used in a lower voltage grid.
