摘要
The paper demonstrates the possibility to enhance the damping of inter-area oscillations using Wide Area Measurement (WAM) based adaptive supervisory controller (ASC).. A damping controller based on the mixed-sensitivity linear matrix inequality (LMI) approach with pole-placement restriction is designed. The ASC uses the input information from conveniently located Phase Measurement Units (PMU) in the system and dispatches supplementary control signals to the available local controllers. Different input signals to the ASC, i.e., frequency and active power generators are used and corresponding ASC performances compared. The design of the ASC is explained in detail and its performance validated by frequency and time domain simulations on a 4-machine 2-area test system.
