Hello,
I'm working of a simulation of a turbine generator that will be used for operator training. So far its working pretty well, but I have a question about the load limiter screen. the turbine itself is a GE steam turbine. using a Mark VI control system. On the example of their load limiter screen that I have from the Mill, there are 3 digital representations of analogue gauges on the bottom. They are labeled VI COIL CURRENT(R) V1 COIL CURRENT(S) AND VI COIL CURRENT(T) respectively. As an example, the bottom left "gauge" is reading 8.44, with a range of -30 to 30. Below it are 2 readings labeled Reg reference, and Reg Feedback, and they read 8.4% and 75.7% respectively. What are these numbers actually measuring/controlling? At this state, the Unit is producing 22.9 MW and 7.6 MVAR and is at 110% Load limit. The unit is running in exhaust pressure control. My guess is that this has to do with the 3 phases on the stator, but what specifically it measures or controls, I'm not sure. Any info would be appreciated.
Thanks
