Abstract-This paper presents a fully analog demonstrator based on power system emulation for high-speed power system stability analysis. A benchmark using a fixed two-machine topology has been implemented. The characteristics of the emulated components (i.e., generators and transmission lines) are reprogrammable and short circuits can be emulated at different distances from the generator. This first realization is limited to transient stability analysis, as the main focus during design was put on computation speed. Indeed, the emulated phenomena are 10 000 times faster than real time. Moreover the authors aim to emphasize that such highly dedicated computation architectures are not only competitive in terms of speed, but also in terms of modularity.Index Terms-Analog emulation, analog integrated circuit, application specific integrated circuit (ASIC), power system simulation, power system stability.

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.

Abstracts-An analog electronics emulation solution is investigated in order to assess the state of a power system facing dynamic phenomena such as the transient stability. Two approaches are studied: DC emulation and AC emulation. Both are intended to be integrated on VLSI submicron CMOS silicon technologies. This implementation has the advantages of presenting low cost, fast simulation time that is independent of the network size and the number of the generators connected to it, low power consumption and small size.
