摘要

电压跌落和膨胀在我们的供电系统中很常见。可调速驱动器易受电压骤降的影响，这是由于电力系统故障造成的。有不同的技术可以提高ASD在电压下降和膨胀条件下的穿越能力。这些旨在通过从外部源注入能量来保持直流链路电压恒定。Buck-Boost转换器在凹陷和膨胀条件下保持ASD直流母线电压。本文给出了仿真结果来验证所提出的Buck-Boost转换器拓扑结构。Buck-Boost转换器在凹陷和膨胀期间提供穿越能力。

Simulation of ride through capability of adjustable speed drive for type A and type B voltage sags and well using Buck-Boost converter

Voltage sags and swell are common in our supply systems. Adjustable Speed Drives are susceptible to voltage sags occurring due to faults in electric power systems. There are different techniques to enhance ride through capability of ASD's during voltage sag and swell conditions. These are aimed at maintaining the DC-link voltage constant by injecting energy from an external source. The Buck-Boost converter maintains the ASD dc bus voltage under sag and swells conditions. In this paper, simulation results are presented for the verification of the proposed Buck-Boost converter topology. Buck-Boost converter provides the ride-through capability during sag and swell.
