In analogue emulation, a non-linear system model is implemented as a set of reconfigurable analogue circuits. This hardware is actuated, initialised and allowed to settle to a steady state, during which time the user utilises voltage and current measurement devices to observe the system's transient response and static solution. In this study, the authors present the advantages of analogue emulation over digital simulation for fast steady-state and dynamic power system analyses, as required in real-time network operation. They discuss the design, fabrication, construction and testing of a multi-bus power system emulator with focus on a reconfigurable analogue circuit to mimic load. They utilise circuit theory to analyse its operation and present a set of design modifications aimed at improved accuracy.
