Research on Short-Delay Adaptive Current Protection Scheme for Shipboard Electrical Power Systems

Abstract:

For specific mission and unique configure of Shipboard Electrical Power Systems (SEPS), their relay protection schemes are different from Terrestrial Electrical Power Systems (TEPS). With development of system capacity and network topology, the traditional three-step current protection method can not meet protection demands, which has the feature of off-line setting. Based on the characteristic and requirement of SEPS, a new short-delay adaptive current protection scheme is proposed, which can automatically adjust current settings of short-delay protection on-line according to the system operation state. Simulation results of typical instance verify the feasibility and validity to improve protection performance.
