The Excel file is used to define only the incoming and outgoing pins described in the tables in the Pins section. In case of CYME, both I/O pins for positive sequence components and 3-phase components are supported that are listed in Native Library section. This file can be in either XLS or XLSX type. For each component of the system in the netlist, ePHASORSIM automatically creates a unique internal ID. To create an incoming or outgoing pin for any component, the user needs to declare this unique ID of the component in the Pins page of the Excel file.
The convention for these internal IDs is based on the ‘name’ and ‘number’ given in CYME’s netlist. The following table lists these conventions:
The Format of the Identifiers in CYME and Excel File
Component in CYME
Component ID in ePHASORSIM
bus_[Name], bus_[Name]_a, bus_[Name]_b, bus_[Name]_c
ePHASORSIM automatically splits the three-phase buses to three one phase buses.
dload_[Number]_from , dload_[Number]_to
ePHASORSIM automatically splits the distributed load between ‘from’ and ‘to’ buses
Shunt capacitor and reactor
sw_[Number], sw_[Number]_a , sw_[Number]_b , sw_[Number]_c
ePHASORSIM automatically splits the three-phase switch to three one phase switches.
br_[Number], br_[Number]_a , br_[Number]_b , br_[Number]_c
ePHASORSIM automatically converts a three-phase breaker to three one phase breakers.
fu_[Number], fu_[Number]_a , fu_[Number]_b , fu_[Number]_c
ePHASORSIM automatically converts a three-phase fuse to three one phase fuses.
rc_[Number], rc_[Number]_a , rc_[Number]_b , rc_[Number]_c
ePHASORSIM automatically converts a three-phase recloser to three one phase reclosers.

Power System Stabilizer
Here is some examples to illustrate the convention:
|A bus with ‘NodeID’ 30||-->||3 buses with the ID: bus_30_a, bus_30_b, bus_30_c|
|A spot load with ‘Number’ 123||-->||MultiPhaseZipLoad with ID: load_123|
|An overhead line with ‘Number’ 802_to_806||-->||MultiPhasePiLine with ID: line_802_to_806|
|A shunt Capacitor with 'Number' 17||-->||MultiPhaseShunt with ID: sh_17|
|A shunt Reactor with 'Number' 18||-->||MultiPhaseShunt with ID: sh_18|
A switch with 'Number' 100
|-->||Switches with IDs: sw_100_a, sw_100_b, sw_100_c|
A fuse with 'Number' 208
|-->||3 separate Switches with ID: fu_208_a, fu_208_b, sw_208_c|
A transformer with 'Number' 209
|-->||MultiPhaseTransformer with ID: xf2w_209|
|A source with 'Number' 210||-->||ThreePhaseVoltageSource with ID: vs_210|
