High-speed, mixed-signal emulation for power system dynamic analysis

This paper presents two different demonstrators of electronic hardware platforms, dedicated to power system emulation. They use DC emulation approaches of an AC power system. Both demonstrators focus on the speeding-up of the temporal analysis of a power system. The first demonstrator proves the feasibility of such programmable hardware. Moreover, comparison with a reference numerical simulator is used to confirm the accuracy of obtained results. The effect of analog-to-digital (A/D) and digital-to-analog (D/A) electronic conversion on the accuracy is also analyzed. The second hardware platform aims to improve generator and load models. At the same time, it also increases the flexibility of the hardware demonstrator platform.
