Electrical Machines Two synchronous generators operating in parallel 200 MW and 400 MW respectively. The drooping characteristics of their governors are 4% and 5% from no load to full load. Consider the governors operating at 50Hz on no load. How will the machine share, if the load is 600 MW? None of these 200 MW and 400MW generator 2 gets over load generator 1 gets over load None of these 200 MW and 400MW generator 2 gets over load generator 1 gets over load ANSWER DOWNLOAD EXAMIANS APP
