We are simulating a hydro power plant and are stuck at the input to the Vstab of Excitation system Block. What is this block?

Hi Prakhar,
Input ‘vstab’ of Excitation System Block is a stabilization voltage which provides additional stabilization of power system oscillations and needs to be connected to Generic Power System Stabilizer Block output.
Inputs to Generic Power System Stabilizer Block can be either synchronous machine speed deviation ‘dw’ signal or synchronous machine acceleration power, Pa = Pm - Peo (difference between the machine mechanical power and output electrical power). Output of Synchronous Machine Block is a vector containing measurement signals and to get ‘Pm’ and ‘Peo’ signals use Bus Selector Block to demultiplex these signals.
Hope this helps!
