Numerical methods in digital real-time simulation

FPGA-Based Real-Time Digital Simulation

1 – This paper is an effort to develop an FPGAbased real-time digital simulator. FPGA is used instead of parallel processors to simulate electromagnetic transients in power systems. A sample single-phase test systems was used to examine the principle. The mathematical model for the power system under consideration is implemented and simulated using Xilinx ISE 4.2 software and ModelSim simulator.

The treatment of inputs in real - time digital simulation

Real-time simulation often requires a computer to interact with external hardware in a dynamic loop. Data must be sampled from input signals and incorporated into the numerical integration algorithm to evaluate the derivatives of the state variables. Also, data from the integration must be available for external use with a minimum of delay. This paper will show that, because of these requiremen...

Real time numerical simulation and visualization of electrochemical drilling

Gas turbines have to be provided with holes in order to provide cooling; these holes are made using an electrochemical drilling technique. Since this process is tedious and expensive, computer simulations are very useful. Such a model needs to incorporate the relevant physical processes. A simulation system including real time user interaction and visualization together with efficient numerical...
