  1. 1. Feasibility of HVDC for city infeed

    University dissertation from Stockholm : Elektrotekniska system

    Author : Paulo Fischer de Toledo; [2003]
    Keywords : ;

    Abstract : It is well recognized that direct current and direct voltageoffer special advantages for both land and sea cable systems,both with regard to power transmission capability, losses, aswell as possible transmission length due to no capacitivecurrents. As cable systems were used very early in largecities, one of the first applications considered for HVDC wasto use it for city infeed and some schemes were also built. READ MORE
