Use of a tubular linear induction motor in a HVDC breaker

Tubular Linear Induction Motor， Computational Electromagnetics， HVDC breakers

Nowadays, due to the increasing development of the energy harvesting from remote renewable resources (solar cells in deserts or off-shore wind plants), the interest in multi-terminal high voltage direct current (HVDC) grids is really high. Availability of HVDC breakers is an essential prerequisite. As known, the interruption of a direct current is harder than an alternate one, because of the absence of a natural zero of the current. Attention is focused on the development of fast electromechanical actuators to interrupt a direct current at high values of voltage. The aim of this work is to investigate the use of a linear tubular induction actuator for the same purpose
