Formulating requirements for a universally applicable power theory as control algorithm in power compensators

Abstract

Abstract Different power theories are examined, with regard to their applicability in controlling dynamic filters for non‐active power. Frequency‐domain approaches and a range of time‐domain approaches are considered, the latter being inherently more suitable for real‐time control of dynamic filters. Finally, some detailed attention is devoted to a combination of the approaches by Fryze, Buchholz and Depenbrock. This FBD‐approach leads to a general time‐domain resolution of power components in a generalized m‐wire system that can be used effectively in deriving control algorithms for dynamic filters of non‐active power.
