Abstract
Direct Current (DC) transmission systems are widely recognized offering significant potential for long distance high power delivery. DC circuit breakers are a key enabling technology for managing faults in multi-terminal DC networks (MTDC). However, DC current breaking is much more challenging than in AC systems because there is no natural zero-crossing of the current to isolate the fault. Superconductor materials are ideal for DC networks because they do not incur any losses when operating with pure DC current. A superconducting hybrid DC circuit breaker, which uses the intrinsic characteristics of the superconductor material, has the potential to offer low operating losses and fast operation.
This paper focuses on the operation analysis and design of the superconducting hybrid DC circuit breaker. A low voltage DC circuit breaker prototype has been built using a multi-strand Magnesium Diboride (MgB2) coil, a vacuum interrupter and an IGBT module. This prototype successfully demonstrated interrupting 500 A DC within 4.5 msecs. The paper also includes a detailed analysis of the test results and the implications for practical
