This repository contains a power system library (PSL) for the Numerical Propulsion System Simulation (NPSS) software framework. It contains circuit components such as resistors and capacitors, electric machines, and ports that are used to link them together. The library also includes bus components that allow more than two elements to be connected to a single node.
Several examples are included in the library to demonstrate the use of the various components, and how they may be connected to an NPSS gas-turbine engine model.
If you have your NPSS environment set up, you can run a model like so:
runnpss-psl run\[file_name].runNOTE: You must run this command from the project root directory (containing "src", "model", etc).
If you run the baseline example, "baseline.run," you should get an output that looks like this in the file "engine.viewOut":
