Question

When two identical a.C generating units are operated in parallel on governor control, and one machine has a 5% governor droop and the other a 10 % droop , the machine with the greater governor droop will select one:

Answer 1

Answer:

Tend to take the lesser portion of load changes.

Explanation:

• In this question, we have been told that two identical A.C. generating units are operated in parallel on governor control.
• We know that governor droop simply means the governor response attribute or characteristic, describing the reduction in the frequency that is required to cause generator output which helps it go from a zero load to full load.
• One of the two machines has a $5 \%$ governor droop.
• The other machine has a $10 \%$ governor droop.
• In a situation like this, the machine with the greater governor droop, i.e., the machine having a governor droop of $10 \%$ will tend to take the lesser portion of load changes.

Hence, the machine with the greater governor droop will tend to take the lesser portion of load changes.
