This paper proposes a non-symmetrical permanent-magnet linear motor traction system (PMLMTS), in which the primary permanent-magnet linear motor (PMLM) is employed. Four movers are mounted with same phase angles. There are nine legs, including eight independent legs and one common leg. All legs have same normal voltage but different normal currents. The normal current of the common leg is four times...
Based on the virtualization technique in optical networks, virtual transport network services (VTNS) has been introduced as a new kind of service in transport networks. With VTNS, transport providers are able to provide their customers entire virtual topologies instead of traditional end-to-end connections. This letter analyzes the new characteristics (i.e., multiple operators, diversified services)...
Distribution network reconfiguration is a multi- objective and discrete nonlinear combinatory optimization problem. In this paper, a novel multi-object distribution network reconfiguration method is proposed based on system homogeneity. Firstly, the relationship between power loss and reliability of systems with different homogeneity is analyzed. Then, to enhance system reliability and homogeneity,...
