The Design and Research Analysis of HVAC System Three-Phase Energy-Draining Fault Current Limiter

In high-voltage AC power grids, the DC component of short-circuit current can cause serious structural and functional damage to the power equipment. In this paper, the design and research anlyis of HVAC system Three-Phase Energy-Draining Fault Current Limiter (TDEDFCL) is proposed. And the accuracy and effectiveness of the structure of the TDEDFCL are proved by simulation.
