HI, i am in learning phase of PSSE . during load flow of PV plant ,tap configuration is not working. i set tap position 33 and control mode 1-voltage and set LV side of GSU transformer as controlled bus. but in leading and lagging mode tap configuration remain same . is this related to * meter on from end * winding 1 on from end
??
Regards PK
Since you say that you are in the "learning phase" of PSS/E this means that there could be a number of causes. Have you set a large enough range for changing the tap ratio? Have you enabled transformer tap changing in your calculation? ... The best thing for you to do is share some screenshots of the power flow calculation dialog and also the transformer data dialog; then there is a better chance for contributors to help you.
What is the actual voltage at the controlled bus?
What are the values of Vmin and Vmax for the transformer tap changer controller?
actual voltage is 34.5 KV , low voltage side of GSU transformer. high voltage side of transformer is 138 KV .Vmin-1.01pu Vmax - 0.99 pu
What is the bus base voltage in kV? Is Vmin 0.99 and Vmax 1.01 pu? What is the scheduled voltage setpoint for the generator?
