Reduction of no-load losses in distribution transformers by using amorphous ribbons Malick MOUHAMAD LME (Laboratoire des Matériels Electriques), Réseau de distribution d'électricité THESE DE DOCTORAT DE L’ECOLE NORMALE SUPERIEURE DE CACHAN

Résumé La présente étude traite l’application des rubans amorphes dans les transformateurs de distribution dans l’objectif de réduire les pertes dans le réseau d’électricité. Les matériaux utilisés sont un alliage à base de fer, silicium et bore. Les premières études sur ce matériau amorphe révèlent une très bonne compatibilité chimique de ces derniers avec les huiles de transformateur. Ces rubans possèdent des durées de vie entièrement conforme aux exigences d’ERDF.

Because DC distribution system has more numerous advantages than AC distribution system,aircraftand shipshavebeen applied to the DC distribution system.because consumer and office equipment consisting of the electronic systems use DC power,the powercan be easily supplied to the load using simple power conversion system.especially,high efficiency power transmission is possible because the power conversion step supplying the power to the electronic load is small in DC distribution system.however,due to the power grid of land consisting of AC powergrid,most of the land power system are applied to the AC distribution system except for special cases such as IDC(InternetDataCenter) and etc. In this paper,design and control method of DC distribution system which can be connected with AC distribution system of land is proposed.In addition,it proved that the connection of renewable energy can bemore easily connected with DC distribution system than AC distribution system by connecting DC distribution grid with renewable energy such as wind power of PMSG type and photovoltaic system through the simulation and experiment. Three-phase AC/DC PWM converter can supply DC 380[V]to the DC bus in case that AC power distribution voltage is AC 220[V].however,because the secondary side of the transformer consists of Y connection and 380[V]in most of the commercial building,in order to configure a DC distribution system,it is boosted to DC 700[V]using three-phase AC/DC PWM converter.And then,the DC distribution system of DC 380[V] was constructed using non-isolated bidirectional DC/DC converter
