Abstract

Voltage sags, transients, and momentary interruption of power together constitute 92% of the PQ problems encountered by typical industrial customers. The series-parallel connected dynamic sag corrector (DySC) provides statistically significant protection at greatly reduced cost. The DySC is rated 1.5 kVA 1-phase to 2000 kVA 3-phase and features a patented single stage power conversion circuit with minimal stored energy. A unique circuit allows operation with opened upstream circuit breaker. The paper presents a detailed discussion of DySC operating principles and validation of performance. It also provides conditions under which this new category of product can be applied.

动态凹陷校正器:具有成本效益的工业电力线调节

电压骤降、瞬变和电力瞬间中断共同构成了典型工业客户遇到的92%的PQ问题。串并联连接的动态凹陷校正器(DySC)在大大降低成本的同时提供了统计上显著的保护。DySC的额定电压为1.5 kVA单相至2000 kVA三相，具有专利的单级功率转换电路，存储能量最小。一个独特的电路允许操作与开放的上游断路器。本文详细讨论了DySC的工作原理和性能验证。它还为这种新产品的应用提供了条件。
