GB Network
The GB Network is a 50 Hz reduced-order representation of the Great Britain transmission grid with 87 buses and 37 synchronous machines (thermal and CCGT units with AVR/PSS and governor models), shunt compensation, and HVDC interconnections modelled as two-port converter injectors. It is used for dynamic simulation and wide-area monitoring/control studies; a one-line diagram is included in the repository.

Quick Start
Section titled “Quick Start”import stepss
case = stepss.cfg()case.addData('GBdyn.dat') # dynamic data: machines, exciters/PSS, governors, loadscase.addData('GBhvdc.txt') # HVDC interconnection two-port modelscase.addData('GBvoltrat.dat') # power-flow solutioncase.addData('settings.dat') # solver settingscase.addDst('disturb.dst') # 180 s run with commented disturbance templatescase.addObs('obs.dat') # observables to record
sim = stepss.sim()sim.execSim(case)The disturbance file contains ready-made (commented) templates for line and machine trips, bus faults, and HVDC parameter changes; uncomment and adapt them as needed. Alternatively, run the RAMSES executable directly with the included cmd.txt.
