3. PMSM SH Local Control (Archived)

This guide provides an in-depth overview of the PMSM SH Local Control example included in the OPAL-RT Power Electronics Add-On for NI VeriStand. We will discuss deploying, running, and monitoring the simulation in real-time.

The eHS circuit model used in this example was created using the Simscape Electrical Specialized Power Systems Simulink Blockset. It represents a grid-tied, three-phase diode rectifier for charging the DC Link, as well as a two-Level, three-phase universal bridge. The bridge is electrically connected to the PMSM SH model through the project configuration. We generate three sine waves using the built-in FPGA signal generators to simulate the Va_in, Vb_in, and Vc_in AC sources in the electrical circuit. The universal bridge gates in the Inverter block are controlled using signals from the Sinusoidal PWM generators. The PMSM calculated currents are fed back to the universal bridge through the current sources Ia_pmsm and Ib_pmsm. Nominal operating speeds of the example PMSM are between 1500 and 3000 RPM.
