A power system is having three identical generators and negligible transmission losses Generator 1 and Generator 2 have governors with a drop of 5% and 10% respectively while the speed governor of G1 maintains its speed constant at rated value. Let generation of three generators be G1, G2, and G3 respectively. If the load of the system is increased which of the following happens.
- a)Generation of G3 increases, while that of G1 and G2 remains constant.
- b)Increase in G1 generation is more than increase is G2 generation, while G3 remains constant.
- c)Increase in G2 generation is more than an increase in G1 generation, While G3 remains constant.
- d)Increase in G1, G2 and G3 generation is equal.
Correct answer is option 'C'. Can you explain this answer?

A power system is having three identical generators and negligible tra...
Generator with more speed regulation will share more load.
As regulation of G2 > regulation of G1, hence increase is G2 generation is more than increase in G1 generation.
G3 will not share any load as its regulation is zero.

Explanation:
To understand the answer, let's analyze the given information step by step.
1. Governor Characteristics:
Generator 1 has a governor with a drop of 5%, while Generator 2 has a governor with a drop of 10%. The governor's drop refers to the percentage change in generation for a given change in load. A higher drop means that the generator's output will decrease more for a given increase in load.
2. Generator 1:
The speed governor of Generator 1 maintains its speed constant at the rated value. This means that regardless of the load increase, the generation of Generator 1 will remain constant.
3. Negligible Transmission Losses:
The power system has negligible transmission losses, which means that the total load demand is met by the generators only. Therefore, any increase in load must be met by increasing the generation of the remaining generators.
4. Increase in Load:
When the load of the system is increased, the generation of the three generators will be affected as follows:
a) Generation of G3 increases, while that of G1 and G2 remains constant:
This option is not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 remains constant.
b) Increase in G1 generation is more than the increase in G2 generation, while G3 remains constant:
This option is also not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 remains constant, and it does not increase more than G2.
c) Increase in G2 generation is more than the increase in G1 generation, while G3 remains constant:
This option is correct. Since Generator 2 has a governor with a higher drop (10%) compared to Generator 1 (5%), it will increase its generation more for a given increase in load. This means that the increase in G2 generation will be more significant than the increase in G1 generation.
d) Increase in G1, G2, and G3 generation is equal:
This option is not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 does not increase.
Therefore, the correct answer is option 'c' - the increase in G2 generation is more than the increase in G1 generation, while G3 remains constant.
To understand the answer, let's analyze the given information step by step.
1. Governor Characteristics:
Generator 1 has a governor with a drop of 5%, while Generator 2 has a governor with a drop of 10%. The governor's drop refers to the percentage change in generation for a given change in load. A higher drop means that the generator's output will decrease more for a given increase in load.
2. Generator 1:
The speed governor of Generator 1 maintains its speed constant at the rated value. This means that regardless of the load increase, the generation of Generator 1 will remain constant.
3. Negligible Transmission Losses:
The power system has negligible transmission losses, which means that the total load demand is met by the generators only. Therefore, any increase in load must be met by increasing the generation of the remaining generators.
4. Increase in Load:
When the load of the system is increased, the generation of the three generators will be affected as follows:
a) Generation of G3 increases, while that of G1 and G2 remains constant:
This option is not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 remains constant.
b) Increase in G1 generation is more than the increase in G2 generation, while G3 remains constant:
This option is also not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 remains constant, and it does not increase more than G2.
c) Increase in G2 generation is more than the increase in G1 generation, while G3 remains constant:
This option is correct. Since Generator 2 has a governor with a higher drop (10%) compared to Generator 1 (5%), it will increase its generation more for a given increase in load. This means that the increase in G2 generation will be more significant than the increase in G1 generation.
d) Increase in G1, G2, and G3 generation is equal:
This option is not correct because Generator 1 maintains its generation constant regardless of the load increase. Therefore, the generation of G1 does not increase.
Therefore, the correct answer is option 'c' - the increase in G2 generation is more than the increase in G1 generation, while G3 remains constant.
