需求越来越高质量、可靠的电力和越来越多的扭曲载荷可能导致电能质量由顾客意识的加强和公用事业。今天最常见的电能质量问题是电压凹陷、谐波失真和低功率因数。的重要性之间的权衡,效率,成本的大小,任何电压凹陷度过系统是选择最好的拓扑结构的核心。此外,选择最好的拓扑对于任何给系统取决于自然中断。例如,如果主要中断事件是电压凹陷;不是完全中断,度过系统先进的硬件修改ASD的类别是首选。反之亦然,如果占主导地位的事件是一个完整的停机,ASD的度过机制能源存储设备类别是最好的为了维持度过很长时间。摘要电压凹陷度过的ASD的先进的硬件修改类别将调查。该系统利用提高转换器以及超级电容器作为储能装置在对称电压补偿直流环节电压凹陷状态。刺激激活转换为补偿直流环节的参考电压之间的差异和实际的电压一旦接收到信号的电压凹陷检测系统。 An additional advantage of using boost converter is its ability to improve the shape of the supply currents waveforms during the steady state normal operation. Thus lower total harmonic distortion (THD) can be obtained. Based on the designed topology, simulation model in MATLAB 7.5 (Sim Power Block set) has been developed for voltage unbalance conditions with supercapacitor as an energy storage device. The designed control technique is modeled, simulated and successfully implemented in the laboratory. The extensive simulation results are provided to validate the proposed system.
