Abstract
A power system, including: a synchronous electrical generator having a rotor; and an angle computation unit configured to: determine a rotor angle in a steady state period of the synchronous electrical generator, determine a change in rotor angle in a transient period of the synchronous electrical generator, and estimate the rotor angle in the transient period based on the steady state rotor angle and the change in rotor angle.

A power system, comprising:
- a synchronous electrical generator having a rotor;
- and
- an angle computation unit configured to:
- determine a rotor angle in a steady state period of the synchronous electrical generator,
- determine a change in rotor angle in a transient period of the synchronous electrical generator, and
- estimate the rotor angle in the transient period based on the steady state rotor angle and the change in rotor angle.
A power system, comprising:
- a synchronous electrical generator having a rotor and an output terminal;
- and
- an angle computation unit configured to:
- determine a load angle in a steady state period of the synchronous electrical generator,
- determine a change in rotor angle in a transient period of the synchronous electrical generator, and
- estimate a load angle in the transient period based on the change in rotor angle, the steady state load angle and a voltage angle at the output terminal.
A computing device configured to determine a rotor angle and/or a load angle in a power system and/or an out-of-step condition by executing a computer program that causes the computing device to perform a method of determining a rotor angle in a power system comprising a synchronous electrical generator, the method comprising:
- determining a rotor angle in a steady state period of the synchronous electrical generator;
- determining a change in rotor angle in a transient period of the synchronous electrical generator;
- and
- estimating the rotor angle in the transient period based on the steady state rotor angle and the change in rotor angle.
