The RTDS Simulator provides instantaneous value outputs in real time, significantly decreasing the time of simulation compared to offline tools. Many hundreds of iterative tests can be automated with a script, with simulation results saved for each case and available immediately for the user’s viewing and manipulation.
Simulating the network in real time means that physical hardware – such as protection, control, or power devices – can be connected to the simulator in a closed loop. Hardware-in-the-loop testing is the only way to validate the behaviour of control and protection equipment from the perspective of how the grid responds to operation or misoperation of the device.
With the increasing complexity of modern power systems, the process of forming an accurate and evaluative idea of the state of a network at any given time can be difficult for operators. Real-time simulation is a safe, controllable, and efficient environment where utility operators can develop fluency in a given portion of the network and its potential control interventions.
The RTDS Simulator may be particularly interesting to utilities considering:
