I/O Pins for CYME Data

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
