This guide provides and overview of the Dual PMSM VDQ 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 (see below). 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 machine model through the project configuration. We generate three sine waves using the built-in FPGA signal generators to simulate the U01 Va, U02 Vb, and U03 Vc AC sources in the electrical circuit. The universal bridge gates SW01_06 INVERTER are controlled using signals from the on-board SPWM generators. The PMSM calculated currents are fed back to the universal bridge through the current sources U04 IaPMSM and U05 IbPMSM.
