Introduction-1 3.1

This work examines the issues of the dynamics of the excitation system of the TVV-800 turbogenerator (with ARV-SDP1) manufactured by PO "Elektrosila". An assumption is made that the turbogenerator operates into an infinite busbar system (system of infinite capacity).

The following issues are considered:

1. Static stability of the control system under small disturbances;

2. Dynamic stability of the control system under large disturbances;

3. Stability of the control system during operation in a power system.

The analysis is carried out using:

- a block diagram in which the connections between individual elements of the control system are mathematically reflected using the transfer functions of these elements;

- logarithmic amplitude-frequency characteristics of the control system without solving the characteristic equations.
