I am trying to build the model of a hydro governor for synchronous generation, and meet some difficulties.
Could you please show me the details of one of the inbuilt model of hydro governors such as "Mechanical-Hydraulic Controls (GOV1)” in the example "sync_exciter_governor" as shown in Fig. 1？ I tried to build one myself for comparison according to the diagram in the example as shown in Fig.2, but I did not find the input "z0", is there anything wrong with the diagram? Could you please help me out? It is highly appreciated!!
