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?

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