This PI System plugin provides a very handy visualization of real time generator operation compared to the limitations.
The unique real time display features a dynamic generator reactive capability curve. The D-curve is plotted with extreme accuracy using true polar coordinates so that the entire limit curve is displayed dynamically around the entire 180 degree plot. Hydrogen pressure (or temperature where applicable) D-curve accurately moves in real time with the actual hydrogen pressure (or temperature) and the reactive/real power is plotted within.
