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

Notes

Bus, Node

bus_[Name], bus_[Name]_a, bus_[Name]_b, bus_[Name]_c

ePHASORSIM automatically splits the three-phase buses to three one phase buses.

Spot load

load_[Number]


Distributed load

dload_[Number]_from , dload_[Number]_to

ePHASORSIM automatically splits the distributed load between ‘from’ and ‘to’ buses

Overhead line

line_[Number]


Cable

cbl_[Number]


Busway

bw_[Number]


Shunt capacitor and reactor

sh_[Number]


Switch

sw_[Number], sw_[Number]_a , sw_[Number]_b , sw_[Number]_c

ePHASORSIM automatically splits the three-phase switch to three one phase switches.

Breaker

br_[Number], br_[Number]_a , br_[Number]_b , br_[Number]_c

ePHASORSIM automatically con­verts a three-phase breaker to three one phase breakers.

Fuse

fu_[Number], fu_[Number]_a , fu_[Number]_b , fu_[Number]_c

ePHASORSIM automatically con­verts a three-phase fuse to three one phase fuses.

Recloser

rc_[Number], rc_[Number]_a , rc_[Number]_b , rc_[Number]_c

ePHASORSIM automatically con­verts a three-phase recloser to three one phase reclosers.

Transformer

xf2w_[Number]


Voltage source

vs_[Name]


Voltage regulator

vr_[Number]


Electronically Coupled Generator (ECG)

ecg_[Number]


Synchronous generator

sm_[Number]


Exciter

exc_[Number]


Governor

gov_[Number]


Power System Stabilizer

pss_[Number]



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
