Introducing the Protection and Automation Suite (PASuite)
Test and validate substation automation protocols with the RTDS Simulator
The all-new Protection and Automation Suite (PASuite) in is a standalone program launched from RSCAD that can communicate with the RTDS Simulator’s GTNET/GTNETx2 card or other external devices compatible with a variety of modern substation automation protocols, as follows: IEC 61850 MMS servers, DNP3 masters or oustations, IEC 60870-5-104 masters, and MODBUS masters.
IEC 61850 MMS Server: The PASuite can be used to simulate IEC 61850 MMS servers using SCL files. Functionality is included in the suite to validate the SCL file prior to simulation. The Suite provides options for configuring the server (including GOOSE message publishing parameters), browsing the IED model and submodels as per the SCL file, and setting values within the submodels (i.e. Data Objects and Data Attributes). The server simulator allows the user to simulate GOOSE communication between an outside IED and the simulated IED. The simulated server can also subscribe to GOOSE messages.
DNP3 Master and Outstation: The PASuite can simulate both DNP3 masters and outstations, allowing the user the ability to poll information from a remote outstation or connect the simulation with a remote master, respectively. The simulated DNP3 outstation’s defined database can be created new or loaded and/or edited by the user. Once the simulation is started, users can be make changes to data elements in the outstation database. When simulating a master, the user can retrieve information from the remote outstation via commands defined by the standard.
IEC 60870-5-104 Master: The PASuite can simulate a master and retrieve information from remote -104 slave stations. Information can be acquired via a number of control commands including General Interrogation (GI). A slave can configure what data is sent in response to a GI.
MODBUS Master: The PASuite can be set up as a MODBUS master and poll information from remote MODBUS slaves. Data is polled via Reference Points and Range Points which define groups of consecutive I.P. addresses on which a given MODBUS command is performed. A variety of standard MODBUS function codes are supported.

Introducing the PSCAD to RSCAD conversion tool
Bring cases from PSCAD into RSCAD for real time simulation with minimal intervention
RSCAD contains several tools for converting and importing circuits developed in other softwares, such as PSSE, CYME, and MATLAB/Simulink. The latest case conversion tool to be released for the RTDS Simulator is the PSCAD to RSCAD Conversion Tool, which takes .pscx files from PSCAD and imports them as Draft files for the RTDS Simulator. PSCAD is a PC-based electromagnetic transient simulation tool – an industry standard power system transient simulation tool used worldwide. The new conversion tool allows users to bring their PSCAD cases into real time using the RTDS Simulator.
The conversion tool uses hierarchy boxes in RSCAD to make managing systems of all sizes easier. Imported cases are automatically split into sections using hierarchy boxes separated by T-lines which exist in the original network. In the example below, the breaker on the receiving end of the T-line in the original case has been automatically absorbed into the RSCAD T-line model’s end-point in order to reduce the node count of the RSCAD simulation.
The conversion tool offers flexible options for changing simulation parameters, creating subsystems, and splitting the network. The rack number, simulation timestep, and the maximum number of nodes per subnetwork are all parameters that can be adjusted from the conversion program. The user can configure subsystems from within the tool itself as well, and has at-a-glance access to the number of load units per hierarchy box and the length of transmission lines in the system. The circuit can easily be split over multiple racks and/or chassis to achieve the user’s desired balance of nodes and component loading.

This is the first post in a series of four covering various features of the newest version of the RSCAD software – Version 5.003.
Introducing GPES: a new FPGA-based power electronics solver
Real time power electronics simulation – custom converter modelling at timesteps in the sub-microsecond range
The all-new general power electronics solver (GPES) supports the real time modelling of power electronics on the RTDS Simulator’s GTFPGA Unit. The motivation behind the development of the GPES is to provide a highly flexible platform for modelling custom converter topologies with a reduced time step. The dedicated, FPGA-based hardware which runs GPES is capable of high-density calculation in parallel with the simulation running on the central RTDS Simulator hardware. Each GTFPGA Unit running GPES can support up to 128 nodes and 256 branches.
GPES uses the same LC modelling approach as the small timestep subnetworks (VSC bridge box) solved on the NovaCor’s processor – however, the GTFPGA Unit’s enhanced computational abilities mean that more nodes, more switches, and a reduced timestep are possible. The smaller time step will result in smaller L and C values for ON and OFF switching state representation which will result in more accurate representation of the switching losses for freely configurable converters.
Similarly to the small timestep subnetwork environment, GPES network development is done within a special GPES bridge box component in RSCAD (shown below). The new GPES tab in the Master Library contains a limited selection of components that can be used within the GPES bridge box. The GPES bridge box connects to a small timestep bridge box running on a NovaCor or PB5. That means the circuit running on GPES can be connected to a model running in the small timestep and exchange control signals with the small timestep. This way, any components required in the case which cannot be modeled on GPES (e.g. machines or dynamic loads) can be modelled in the small timestep as shown below. The GPES also has an Aurora interfacing block that allows firing pulses to be received directly from external controls.
The GTFPGA Unit running GPES is connected with the main RTDS Simulator hardware via fibre cable (connected from the rear of the GTFPGA Unit to the rear of the NovaCor chassis or GTWIF-based rack running the simulation) as shown in the below diagram.

RTDS Technologies is pleased to announce a significant expansion to its production capacity at the RTDS Simulator’s worldwide headquarters in Winnipeg, Manitoba, Canada.
With the release of NovaCor, the newest generation of simulation hardware for the RTDS Simulator, in April 2017, there has been an unprecedented demand for Simulator upgrades and new installations around the world. To meet this demand, RTDS Technologies has expanded its on-site production capabilities in terms of both staff and facilities. Many new production staff have been hired since the release of NovaCor, increasing the size of the production team by almost 50%. The on-site production facility has also expanded into new space, nearly doubling the floor space available for assembling NovaCor chassis and cubicles.
The design, manufacturing, assembly, marketing, servicing and support, shipping, and continued development of the RTDS Simulator is all done out of the RTDS Technologies headquarters in Winnipeg. This allows RTDS Technologies to maintain the highest quality of equipment and support in the industry due to the control over every aspect of our product’s development. Every piece of equipment that leaves the facility has been developed, built and thoroughly tested in-house. The increase in the size of and resources available to our production team will allow us to maintain the same level of quality and comprehensive testing as demand for NovaCor continues to accelerate.
