Power network transient stability electronics emulator using mixed-signal calibration
The emerging field of power system emulation for real time smart grid management is very demanding in terms of speed and accuracy. This paper provides detailed information about the electronics calibration process of a high-speed power network emulator dedicated to the transient stability analysis of power systems. This emulator uses mixed-signal hardware to model the dynamic behavior of a power network. Special design allows the self-calibration of the analog electronics through successive measurements and correction steps. The calibration operation guarantees high resolution of the transient stability analysis results, so that they can be reliably used for operational planning and control on real power networks.
