RSCAD contains specialized components for Power System Protection and Automation. The protective relay models are useful when real devices are not available. They are also highly useful for training and educational purposes.
The descriptions below are by no means an exhaustive list of the available components, but provide an overview of the base components.
Protective Relays
The library includes multifunction distance, overcurrent, differential, and generator protection models.
Power System Metering and Control
The library includes three-phase symmetrical components, impedance measurement with sequence components, 1/3 pole circuit breaker control with sync-check, OLTC control.
Phasor Measurement
The PMU firmware for the GTNETx2 provides P class or M class synchrophasor output data streams according to IEC/IEEE 60255-118-1.
A control PMU component is also available for monitoring PMU output within the simulation (and not streaming to external devices).
IEC 61850
The library includes GOOSE messaging (binary and analog); Sampled Values (IEC 61850-9-2) including data delay, jittery, swap and suppression.
SCADA
The library includes DNP3 and IEC 60850-5-104 components for SCADA applications.
MODBUS
The MODBUS component supports Modbus TCP, Modbus RTU over TCP, and Modbus ASCII over TCP.
GTNET-MODBUS operates as a Modbus server (slave) communicating to a Modbus master station through the GTNETx2’s Ethernet port. This master station can be either an IED on dedicated hardware or a computer workstation running a Modbus master API.
Extended File Playback
This component supports very large file (many GB) playback in COMTRADE or ASCII file format.
