FORMULATING REQUIREMENTS FOR A UNIVERSALLY APPLICABLE POWER THEORY ASCONTROL ALGORITHM IN POWER COMPENSATORS

Different power theories are examined, with regard to their applicabil ity in controlling dynamic filters for nonactive power: Frequency-doma in approaches and a range of time-domain approaches are considered, th e fatter being inherently more suitable for real-time control of dynam ic dynamic filters. Finally, some detailed attention is devoted to a c ombination of the approaches by Fryze, Buchholz and Depenbrock. This F BD-approach leads to a general time-domain resolution of power compone nts in a generalized m-wire system that can be used effectively in der iving control algorithms for dynamic filters of non-active power.
