Commuter Rail AC Electrification Load-Flow Simulation Report Revision 1 Table 9 - Distribution System Impedances – Direct-Fed System Number of Tracks Catenary Resistance (Ohm/mile) Catenary Reactance (Ohm/mile) 1 0.188 0.707 2 0.202 0.813 Simulation Period. The simulations were performed for a morning rush hour period from 8:00:00 A.M. to 10:00:00 A. M. It is assumed that the evening rush-hour is the same. Power Simulation Snapshot Interval. The electrical load-flow simulations were performed in snapshot intervals of 1 second. 02/27/2009 FRSC Page 22 of 250
Commuter Rail AC Electrification Load-Flow Simulation Report Revision 1 8.0 ELECTRICAL SYSTEM SIMULATION RESULTS 8.1 GENERAL The morning and evening rush-hour operation is assumed to be the same, i.e., the same train consists at the same headways, as presented in Table 1 above, will operated in both periods of time. Therefore, the results of the study apply to both rush-hours. 8.2 STUDIES PEFORMED The following two sets of studies were performed: • Set 1 – Two traction power transformers in Sandown substation and two traction power transformers in Argo substation o All systems in service o Argo substation out of service o Sandown substation out of service • Set 2 - Two traction power transformers in Sandown substation and one traction power transformer in Argo substation o All systems in service o Sandown substation out of service It was not necessary to run the Argo substation out of service case in the study Set 2, as the results would be the same as in the study Set 1. 8.3 SYSTEM VOLTAGES The minimum train (pantograph to running rail) voltage for each commuter rail line during all equipment in-service and for contingency operation of each substation out-of-service are shown in the following Table.

However, since the RMS currents were well 02/27/2009 FRSC Page 23 of 250
