So, initially suppose initially the generator it was operating at a nominal frequency f0 right frequency; so you draw horizontal line this thing therefore, when it is operating a your at nominal frequency f0 at that time it was generating power Pg1 this unit 1 generating power Pg1 at the same time this unit 2 or generating power Pg2. So, this is Pg1 per unit 1 and this is Pg2 per unit 2. When it was operating at nominal system frequency say f0 may be 50 Hz for 50 Hz system or 60 Hz for 60 Hz system, right.
त्यावेळी निर्माण झालेली ऊर्जा . ही युनिट1 ची ऊर्जा त्याच वेळी युनिट 2 ची निर्माण झालेली ऊर्जा . तर हे प्रत्येक युनिट 1 साठी ,आणि हे प्रत्येक युनिट 2 साठी . जेव्हा हे नाममात्र प्रणाली वारंवारता कदाचित 50 Hz प्रणालीसाठी 50 Hz किंवा 60 Hz प्रणालीसाठी 60 Hz, काम करेल
