Introduction

“What does it mean the unit is in Droop Control?”
“All the generators in Droop Control collaborate by
picking up or shedding load as needed to maintain the
grid’s frequency.”

Objectives
7 of 31
This short discussion, in layperson’s terms for those
somewhat familiar with gas turbine operations, will try to:
• explain the concept of droop control
• derive some consequences (Preselected Load)
• provide an exercise and example
• explain isochronous control with a simplified model
Considering:
industrial type gas turbine for power generation (6B or 7EA)
a constant droop setting

More Base Load

Question
Given a unit at a specific location, is Base Load
a unique value?

Question (rhetoric)
Are we any closer to an explanation of “Droop
Control”?

Question
When is a gas turbine in “Droop Control”?
For the unit to be in “Droop Control” there are two conditions:
The unit is in “Speed Control”, i.e. below “Base Load”.
(Now we know that when in Speed Control FN < FT and TX < TR)

Question
When is a gas turbine in “Droop Control”?
For the unit to be in “Droop Control” there are two conditions:
The unit is in “Speed Control”, i.e. below “Base Load”.
(Now we know that when in Speed Control FN < FT and TX < TR)
There is no “Preselected Load” function active. In other
words, the unit is “floating” responding to the frequency of the
grid.
THIS IS VERY IMPORTANT.

Review

Simplified concepts involved in Primary Frequency Regulation
For Preselected Load mode, we covered
(a) What happens in case of a frequency change
(b) What the limits are for “true droop response” (Exercise)
