ON LINE STABILIZATION OF THE LARGE hv-ac-dc POWER SYSTEM BY USING OBSERVATION DECOUPLED REFERENCE AS A SYSTEM-WIDE TARGET.
The concept of the Observation Decoupled Reference vector was introduced earlier. It was demonstrated that effective system stabilization can be accomplished based on this new concept using purely local information and local action as the generating stations provided control means such as damping resistors or load skipping are available at each generating station. In this paper the observation decoupled reference vector is considered as a systemwide target to be tracked and approached using a limited number of control devices such as the converter terminals of an overlying HVDC system. The tradeoff is that fast reliable communication between the generating stations and the control center are needed.
