Hi,
i am heaving problem with 'Network not converged' in dynamics simulation.
Simulation is ok with basic machines but when I entered a wind machines it wont work converged.
there is some error:
BUS 60134 MACHINE 1 : Prate of 0 machines with 3.00 MW each is less than Pelec = 9.92 MW
but I dont know whrere to change parameter to avoid error.
This is highly dependent on the Wind Model you are using. Please edit your question to tell us what model you are using. and also show us what parameters you have entered into the dynamics data.
Typically there is an ICON that indicates how many wind generators are being modeled in a single equivalent machine/generator. This error is telling you two things:
The model is assuming each wind machine is 3MW, however it appears that the data you plugged in says there are 0 machines. So you have an active power rating of 0*3MW=0MW.
Your powerflow has resulted in a PELEC (active power injection) at that machine should be 9.92MW... however your rated power is 0MW. Hence the error.
You either need to change your powerflow solution such that the power being produced by the machine is less than the rated power or modify the model such that the rated/max power is higher than the PELEC that was solved in the powerflow. It seems that due to item 1 above your max power/rated power is not correct.
Run a DYDA or DOCU command either directly in PSS/E or via Python. Alternatively take a screen shot of the dynamics data in the PSS/E UI.
