| 摘 要： | 电压暂降可能对企业造成巨大的经济损失,已成为当前最为突出的电能质量问题。以10 kV双电源供电系统为应用背景,提出了一种由多绕组变压器和功率单元构成的电压暂降抑制电源。该电源通过快速开关实现双电源切换,并由直流电容提供电源切换期间的电能供应,从而实现系统电压暂降对供电负荷的抑制和隔离。此外,对功率单元直流电容的参数设计进行了讨论,并通过PSCAD/EMTDC建模,对所提电路以及电容设计方法的正确性和有效性进行了验证。

| Abstract: | Voltage sag has became the most prominent power quality problem, because it may cause great economic loss to enterprises. In this paper, a voltage sag suppression power supply based on multi-winding transformer and power unit was proposed, which could be applied in 10kV dual power supply system. The suppression of voltage sag could be worked by quick switching between the fault and backup AC power sources, and sufficient energy supplying by DC capacitor in power unit during switching time. Then, the parameter design method was discussed, and the correctness and effectiveness of the power supply proposed in this paper was verified by modeling in PSCAD/EMTDC. |
