IEEE steam turbine governor model.
Reference: IEEE Transactions on Power Apparatus and Systems
November/December 1973, Volume PAS-92, Number 6
Dynamic Models for Steam and Hydro Turbines in Power System Studies, Page 1904.
Parameter Notes:
- Per unit parameters are on base of MWbase, which is normally the MW capability of the turbine.
- T3 must be greater than zero. All other time constants may be zero.
- For a tandem-compound turbine the parameters K2, K4, K6, and K8 are ignored. For a cross-compound turbine, two generators are connected to this turbine-governor model.
- Each generator must be represented in the load flow by data on its own MVA base. The values of K1, K3, K5, K7 must be specified to describe the proportionate development of power on the first turbine shaft. K2, K4, K6, K8 must describe the second turbine shaft. Normally K1 + K3 + K5 + K7 = 1.0 and K2 + K4 + K6 + K8 = 1.0 (if second generator is present).
- The division of power between the two shafts is in proportion to the values of MVA bases of the two generators. The initial condition load flow should, therefore, have the two generators loaded to the same fraction of each ones MVA base.
