Kestrel EMT is designed to model and simulate:

• Power electronics, inverter control systems, and smart grid studies
• Design studies such as lightning, switching transient, and breaker transient recovery voltage (TRV)
• Distributed parameter transmission lines and wave propagation
• General transient circuit analysis

Features

• Sophisticated plotting capabilities using KPlot, including time domain, frequency domain, spectrogram, and phasor plots
• Ability to execute Python and MATLAB code from within a simulation and interface with circuit components.
• XML-based, human readable .kcf file format for saved circuits.
• Modern, intuitive ribbon interface
• Export directly to open source HDF5 file format for additional analysis in MATLAB or Python
• Use external data to program arbitrary current sources
• Kestrel is currently under active development and is free for commercial, educational, or personal use.

KPlot

KPlot is a free standalone plotting tool that is included with Kestrel EMT. Interactively plot Kestrel EMT, Siemens PTI PSS/E, PSCAD, and HDF5 files alongside eachother.

KPlot can optionally be installed separately from Kestrel EMT using the same Kestrel EMT Setup Installer.
