Investigation on Stimulation Method and Signal for Steam Turbine Governing System Parameter Identification

In this paper, the stimulation method and signals for the parameter identification of steam turbine governing system are investigated. It is pointed out that the system could be stimulated by the load variation if the unit operated in single or by the synchronizer reset if the unit operated in parallel. The feasibility and identification effect of different stimulation signals are analyzed and compared using simulation test. It is shown that the slope-holding signal is easily to realize and the parameter can be precisely identified with this kind of stimulation signal. Therefore, it is the rational stimulation signal for parameter identification of steam turbine governing system.
