PMU spectrogram

Hover · click to tripTap to trip

Synthetic phasor measurements: a 60 Hz carrier with a lightly damped 0.41 Hz inter-area mode riding on it. Hover to excite the mode, click to trip a line, and watch it ring down at about 4.8% damping in both the spectrogram and the frequency-deviation trace underneath.Synthetic phasor measurements: a 60 Hz carrier with a lightly damped 0.41 Hz inter-area mode riding on it. Tap to trip a line, which excites the mode, and watch it ring down at about 4.8% damping in both the spectrogram and the frequency-deviation trace underneath.

I build point-in-time market data infrastructure; models for nonstationary, multivariate series; systems that catch themselves being wrong; and the tools I kept wishing already existed.

Half the methods I use were invented for something else: earthquakes, missile guidance, machine translation. I keep an eye on where else they might fit, and check whether they transfer before building on them.
