powerformer can act as differential protection scheme for high voltage cable wound generator. Many other applications like stability control, controlling high voltage bus, are mentioned. Key Words: Powerformer, self-adaptive compensation, technology-push. 1.INTRODUCTION Powerformer is a new machine, It is a 3-phase AC generator with a rotor of conventional design. The difference compared with conventional generator lies in the stator windings.

Powerformer is a 3 phase AC generator which is capable of generating output voltage ranging from 30 kv to 400 kv that can be directly connected to the high voltage transmission grid by replacing the generator and step-up power transformer used in todays power plant. replacement of existing generators with the Powerformer. In order to replace an existing generator with the Powerformer for comparison purposes the step-up transformer impedance has been made small enough to be insignificant (less than 1/1000 per-unit). The simulated increase in stator overload capability of the Powerformer compared to conventional 2005-06-01 used in this study (conventional generators and powerformersTM).

Power levels of 25 GW will be injected into a HPM radiator during 200 ns. The source generator has to deliver a 50 kA current … The Powerformer is able to maintain an overload in its stator windings for a longer period than a conventional generator. This means that Powerformer may provide reactive support for an extended period of time compared to a conventional generator. The benefits of this overload capability in improving voltage For a synchronous electric generator an earth fault detection or protection circuit is provided using extracted (35A, 35B, 35C) third order harmonic currents (Ia3, Ib3, Ic3) in the phase windings (1A, 1B, 1C) at locations at the neutral point (N, 5).

In a conventional system, electricity is generated at voltages that are too low to be efficiently transmitted through a power grid. Powerformer is a new generator that can be directly connected to the transmission network without the need for a step-up transformer. The ability of powerformer to generate electricity at transmission voltage levels offers considerable gain with respect to reactive power production and plant efficiency.
