Details
Excitation control results from phase controlling the output of the SCR bridge
circuit. The SCR firing signals are generated by digital regulators in the controller.
In the redundant control option (Figure 1-2), either M1 or M2 can be the active
master control, while C monitors both to determine which should be the active and
which the standby controller. Dual independent firing circuits and automatic tracking
is used to ensure a smooth transfer to the standby controller.
Microprocessor-based controllers (ACLA and DSPX) execute the exciter control
code. The software consists of modules (blocks) combined to create the required
system functionality. Block definitions and configuration parameters are stored in
flash memory, while variables are stored in random-access memory (RAM).
The exciter application software emulates traditional analog controls. It uses an open
architecture system, with a library of existing software blocks configured from the
toolbox. The blocks individually perform specific functions, such as logic gates,
proportional integral (P.I.) regulators, function generators, and signal level detectors.
The control selects one of two modes, either generator voltage regulation (Auto
Regulation), or direct control (voltage or current, depending upon the application).
Generator protection functions are integrated into the control, including over and
under-excitation limiting, power system stabilization, and V/Hz limiting.
The blocks can be interrogated while the exciter is running by using the toolbox. The
dynamically changing I/O values of each block can be observed in operation, which
is valuable during startup or troubleshooting.
