Electrical Machines Two synchronous generators operating in parallel 200 MW and 400 MW respectively. The drooping characteristics of their governors are identical as 4% 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? 200 MW and 400MW respectively generator 1 gets over load generator 2 gets over load 230.7 MW and 369.23 MW respectively 200 MW and 400MW respectively generator 1 gets over load generator 2 gets over load 230.7 MW and 369.23 MW respectively ANSWER DOWNLOAD EXAMIANS APP
