Real-time Implementation of a Measurement-based Adaptive Wide-area Control System Considering Communication Delays

Abstract

A wide-area control system (WACS) uses wide-area measurement signals to provide auxiliary stabilising controls to power system devices. An adaptive WACS has been designed to provide damping control signals to the excitations of generators. The delays in signal transmission and the reliability of the communication network is a major concern with wide-area measurement-based control. The adaptive WACS is designed to compensate for a wide range of communication delays and provide robust damping to mitigate system oscillations. A single simultaneous recurrent neural network is used in the realisation of the adaptive WACS for both identification and control of the power system. The WACS has been implemented on a digital signal processor and its performance is evaluated on a power system implemented on a real-time platform - the real-time digital simulator. The additional damping provided by the WACS is enumerated using Prony analysis.
