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 close to their short-circuit limits. The interphase power controller is a new concept for the control of active and reactive power; it uses only standard components connected in an original manner. The paper gives the results of EMTP simulations for the conditions governing the design of the components. The significant steady-state and transient capabilities of the components are given as well as insulation coordination and protection aspects. Finally, a preliminary layout is presented for the prototype.<
