An integral backstepping controller design for compensated distribution networks with rapid earth fault current limiters in bushfire prone areas

This paper presents a nonlinear integral backstepping controller (I-BSC) design scheme for T-type residual current compensation (RCC) inverter used in compensated distribution networks with rapid earth fault limiters (REFCLs). The major control task the proposed is to reduce value suitable mitigation of powerline bushfires due single phase-to-ground faults networks. key distinct feature I-BSC over traditional (T-BSC) that it introduces an action analyzing dynamic tracking error which minimizes its steady-state and ensures better performance. In order prove global asymptotic stability RCC (I-BSC), Lyapunov function-based theory used. Finally, performance analyzed on MATLAB/Simulink environment compared T-BSC. both I- T-BSCs assessed terms transient behaviors injected neutral, current, line-to-ground voltage faulty phase ensure standard operational criteria self-extinguishing bushfires. Simulation results clearly demonstrate controllers fulfill standards REFCL-compensated though archives while comparing Results from processor-in-loop (PIL) validations are also included further justify applicability newly real-time environment.
