THE DESIGN OF A 200 MW INTERPHASE POWER CONTROLLER PROTOTYPE

The paper addresses the practical design aspects of a 200 MW prototype for the interconnection of two synchronous 120-kV networks that are c lose to their short-circuit limits. The Interphase Power Controller is a new concept for the control of active and reactive power; it uses o nly standard components connected in an original manner. The paper giv es the results of EMTP simulations for the conditions governing the de sign of the components. The significant steady-state and transient cap abilities of the components are given as well as insulation coordinati on and protection aspects. Finally, a preliminary layout is presented for the prototype.
