The Protection Scheme for the Novel Flexible Short Circuit Current Suppression Technology

This paper discusses on the protection scheme for the novel flexible short circuit current suppression technology, which applies the new-type fast circuit breaker. The challenges of rapidity, selectivity and reliability for the protection are analyzed. The technology principle of the protection is formulated. The improvement project and the logic coordination under different space levels and time scales is proposed. These new method is to guarantee the safe and sound operation of the power system in the new scenario that applies the novel flexible short circuit current suppression technology.
