Guidelines for the setting test of power system stabilizers
1 Scope
This document specifies the test conditions, test items and requirements, and parameter setting of power system stabilizers.
This document applies to steam (gas) turbine generators and nuclear power units with a single unit capacity of 100MW and above, and water turbines with a capacity of 40MW and above.
Generators, pumped storage power generation/motors and CSP units are connected to synchronous generators with voltage levels of 220kV and above. Other units can participate
Follow the execution.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Power system stabilizer;PSS
With the help of an automatic voltage regulator to control the excitation of the synchronous motor, additional control devices or functions to suppress the power oscillation of the power system.
Note. The input variables of PSS can be single variables such as speed, frequency, power, etc., or a combination of the above single variables can be used.

3.2
Reverseaction
When the output power of the prime mover increases or decreases, the excitation voltage, synchronous motor voltage, and reactive power are simultaneously caused by PSS regulation.
The phenomenon of reverse adjustment.
3.3
Uncompensated frequency response characteristics of excitation control system uncompensatedfrequencyresponsefanexcitationcontrolsystem
When PSS exits, the frequency response characteristics of the electromagnetic torque component Te2 generated by the excitation adjustment to the PSS output embedding point signal US
(ΔTe2/ΔUS).
Note. In engineering, the terminal voltage ΔUt is often used to replace the torque component ΔTe2, which is expressed by ΔUt/ΔUS. ΔUS is the excitation added at the PSS output embedding point
Signal.
3.4
