There is a rate limit function in the control system that prevents too large and quick power load changes and in the end limits the temperature transients the microturbine experience. The model response in TOT experiences some time delay and even a small decrease, before TOT starts to increase. This is likely due to unmodelled dynamics. At t = 320 seconds, the measured data shows an extra bump in the TOT signal. At the same time the measured fuel value increases faster than the model’s, which might cause the bump. It can also be caused by unmodelled dynamics and possibly differences in the control system model. The second case is also a step response experiment, but now in stand-alone mode with a simpler speed regulator. The microturbine is set to 5 kW electric power load, i.e. some kind of idle mode. The speed is kept constant at 63 000 rpm. At a given time t the power reference (dashed-dot green) is set to 59.2 kW and is set back to 5 kW after another 45 seconds. 49 TOT (K) Fuel (kW) Power (kW)PDF Image | Modelling of Microturbine Systems
