摘要: Dynamic Voltage Restorer (DVR) is one of the most cost-effective equipment to mitigate voltage sag, which has been widely used. However, application DVR also inevitably influences stability interconnected system. To analyze problems that brings inter-connected system, it necessary study impedance characteristics DVR. In this paper, an model single-phase established based on linear in detail; then, criterion system with deduced using Simulations results indicate model, as well criterion, applicable a wide frequency band.
