Design of hvdc damping controller using pmu data

Abstract

This paper describes a novel method to design a supplementary HVDC damping controller for damping the power oscillations in the electrical network. The electrical network of Karnataka and Tamil Nadu is the system under consideration and the Raigarh-Pugalur HVDC linkis taken for integrating the supplementary controller. PSSNETOMAC is used for Eigenvalue analysis to identify the oscillatory modes. The test signal method and pole placement method are used for designing and tuning the parameters of the supplementary controller. RTDSTM is utilized for the controller design and implementation. Dynamic analysis has been performed to validate the effectiveness of the designed controller.
