3 Terms and Definitions

The terms and definitions defined in GB/T 26863 and the following apply to this document.

3.1

The speed of each generator set is adjusted by the speed governor of each prime mover, so that the driving torque varies with the system frequency.

[Source. GB/T 26863-2011, 6.29.1.5]

3.2

The primary frequency modulation regulation system is insensitive to the speed difference or frequency difference near the rated speed.

3.3

From the last time the speed difference or frequency difference exceeds the frequency modulation dead zone to the time when the unit load starts to change in the correct frequency modulation direction time.

3.4

The allowable range from the last time the speed difference or frequency difference exceeds the frequency modulation dead zone to the last time when the unit load reaches the target value within the time required.

3.5 Speed droop droop

The slope of the static characteristic curve of the steam turbine control system. Usually, the ratio of the speed difference corresponding to the empty load and full load to the rated speed expressed as a percentage.
