Table 4: Data Requirements (Transformers) Field Description Requirements Measure FROM Bus Number Number of the bus to which the FROM end of the transformer is attached. See “” TO Bus Number Number of the bus to which the “TO” end of the transformer is attached. See “” Circuit ID Circuit identifier Two-character circuit identifier Transformer modeling equivalent circuits shall have Circuit ID set to ‘99’ or ‘EQ.’ Status Transformer Status 0 = out-of-service 1 = in-service 2 = secondary open 3 = tertiary open 4 = primary open Transformers shall have the anticipated status of the transformer in the case. Tap Control Type Transformer type code 1 or 11 = Fixed 2 or 12 = TCUL 4 or 14 = Phase-Shifting Regulated Bus Number Number of Bus with voltage regulated or “TO” bus number for phase-regulated transformer Regulation of a remote bus that does not represent actual system operation shall be avoided. Impedance Table Number Impedance correction table number Tert Bus Number Tertiary winding Bus number See “” 3wpt Bus Number Internal ‘3-winding point’ Bus number See “Data Requirements (Buses)”
SVD Status SVD status 0 = out-of-service 1 = in-service Controlled shunts shall have the anticipated status of the shunt in the case. SVD Control Type Device type 0 = Fixed 1 = Discrete 2 = Continuous 3 = All or Nothing 4 = Discrete control using Voltage Dead Band 5=WECC SVC 6=WECC STATCOM 7=WECC TSC/TSR Regulated Bus Number of Bus regulated by this shunt See “” Regulation of a remote Bus that does not represent actual system operation shall be avoided. Area Area in which Controlled Shunt is located Refer to “” for designated Area. Zone Zone in which Controlled Shunt is located Refer to “” for designated ranges of Zones used by Area.
