Commuter Rail AC Electrification Load-Flow Simulation Report - RTD

Commuter Rail AC Electrification Load-Flow Simulation Report Revision 1
Power demand graphs for each corridor are presented in Appendices C, D, E, F, and G.
8.6 AUTOTRANSFORMER POWER DEMANDS
The power demands averaged over 2-hour time interval for autotransformers located in the
switching station and the paralleling stations are shown in the Table 15.
Table 15 - Autotransformer Power Demands – All Systems in Service, Two Transformers
in Sandown Substation, Two Transformers in Argo Substation
SW/AT Station Autotransformer Power Demand (MVA), 2-Hour Average
SW-1, AT-1 0.3
SW-2, AT-2 0.2
PS-1 0.8
PS-2 1.1
PS-3 0.7
PS-4 0.7
PS-5 1.1
PS-6 0.9
Results for two transformers in Sandown substation, and one transformer in Argo substation are
not presented, as the results are not substantially different from the results shown.
Additional load-flow simulation results are presented in Appendices C, D, E, F and G.
