Hello, I would like to see the reaction of phase shifter model in a time domain. How to assign MW to which PST should regulate? The idea is to see dynamics after order from dispatch center. When I try manually change it from previously 197 to 230 (in model VARS) I get message "Model data contains warning and/or errors".
The way I understood the VARs of OLPS1T, VAR (L+3) is only MW flow reference, thus the reason why there is an error or there might be no change in the simulation result.
Simulate a disturbance (e.g. loss of equipment in parallel of Phase Shifter) to force the MW flow across the Phase Shifter under study to exceed its limits. The time delay for transformer tap changers are typically long so ensure the simulation time is sufficient to cover the dynamics of the phase shifter.
I don't think you can change it in dynamic model. The intent is to control the actual power through the transformer during the simulation. Simulate a disturbance so the actual flow goes outside the dead band defined in load flow data of the transformer.
An alternative is to change the dead band data during the simulation, i.e. shift the dead band with x MW in the load flow data of the transformer.
