Real Time Digital Simulator Laboratory (RTDS)

RTDS is short for real time digital simulator which solves power system electromagnetic simulations in real time.

In the RTDS laboratory 1 cubicle of RTDS is installed with 2 rack and 1 set of Giga Transceiver I/O cards (GTIO) inside. Within the rack, there is 1 Giga Transceiver Workstation Interface card (GTWIF) and 5 Giga Processor cards (GPC) with 2 Giga processors each.

Importantly, among all the 10 Giga processors within 1 rack, only 1 will be assigned to deal with the network solution (all other processors will deal with component model solutions). During one simulation as many as 44 buses (3-phase, so totally 132) can be handled.

The GTIO cards include:

  • 1 Giga Transceiver Analogue Input card (GTAI)
  • 1 Giga Transceiver Analogue Output card (GTAO)
  • 1 Giga Transceiver Digital Input card (GTDI)
  • 1 Giga Transceiver Digital Output card (GTDO)

These cards are used to exchange signals with external equipment. Additionally, in the front panel of the cubicle, there are more I/O interfaces such as: a low voltage digital input/output interface panel, a 250Vdc digital output interface panel and GPC front panel analogue output channels.

The software for RTDS simulation is called RSCAD. It has been installed in 4 host computers in the RTDS lab.

The laboratory facilities also include the RT-LAB, which is a distributed real-time platform that facilitates the design process for engineering systems by taking engineers from dynamic models to real-time with hardware-in-the-loop. RT-LAB can be used to design, test and optimize control and protection systems in power grids, power electronics and motor drives. RT-LAB will be used in Power System – Smart grid Lab to study the interactions between wind power plants and connected power systems.
