comes to the rst switch signal input, the output of PSS (as shown in Figure 6.21) with
the input signal as a difference of power (6.17) comes to the second switch signal input,
and the output of PSS according to Figure 6.22 comes to the third switch input. The
value of the constant 0, 1, 2 that comes to the switch control input has to be specied.
A number of scopes are set to observe the processes in the system. The scope
Machines xes the deviations in rotor positions and their rotational speeds from the
synchronous paths and also the voltage amplitudes. The scope System records the ...
