IEEE 421.5-2005 type ST7B model.
This model is representative of static potential-source excitation systems. In this system, the AVR consists of a PI voltage regulator. A phase lead-lag filter in series allows the introduction of a derivative function, typically used with brushless excitation systems. In that case, the regulator is of the PID type. In addition, the terminal voltage channel includes a phase lead-lag filter. The AVR includes the appropriate inputs on its reference for overexcitation limiter (OEL1), underexcitation limiter (UEL), stator current limiter (SCL), and current compensator (DROOP). All these limitations, when they work at voltage reference level, keep the PSS (VS signal from PSS) in operation. However, the UEL limitation can also be transferred to the high value (HV) gate acting on the output signal. In addition, the output signal passes through a low value (LV) gate for a ceiling overexcitation limiter (OEL2). Reference: IEEE 421.5-2005, 7.7.

bitfields: Array[Int]
Valid fields bitmap.
Valid fields bitmap.
One (1) in a bit position means that field was found in parsing, zero means it has an indeterminate value. Field order is specified by the fields array.
For classes constructed manually, we initially fill this in with the worst case scenario. ToDo: this won't work for classes with more than 128 fields (so far none).
