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?

 generator 2 gets over load
 200 MW and 400MW respectively
 230.7 MW and 369.23 MW respectively
 generator 1 gets over load
