CR,
I did not mean to say that the deviation is 0.01 Hz. The frequency deviation is indeed much less than that.
What I meant was that the frequency of gen. speed oscillations around their rated values is ~0.01Hz. It is a slow dynamics between the generator groups from different areas.
And...
I'm new to the forum and also late to this discussion. It's an excellent topic with a lot of valuable information. Here is my understanding of the frequency in the AC power system:
- In synchronously connected AC system, there is one frequency. Every generator is tied to this frequency via the...
