Hello everyone. We are trying to setup an automatic generation control system in a small electrical area (a small island). Due to the small amount of generators in the area, we need all of them contributing to secondary regulation. We are using a load control mode for the generators (gas turbines and diesel motors) that tries to fix a load, making the unit to go to the setpoint dictated by AGC. but when we put all the generators in load control mode, the frequency becomes very unstable. I think the problem is that this load control is interfering with the speed control canceling its decisions. Do you think i'm on the right way?
I think that we have to put enough deadband in this controllers to make them not to cancel speed governor.
Does anybody have experience in setpoint to raise-lower conversion for generation units?
Thanks in advance and sorry for my english.
