Objective

This simulation training session deals with real-time simulations of electric drives and power electronis systems using recent developements in industrial electronics.

 

Outline

This training presents the evolution of real-time simulation technologies of electric drives and power electronics systems and presents related typical applications with experiemntations using Dual-Core Opteron PCs, MX-Stations Core Duo PCs and FPGA cards.
- DC-AC drive with AC feeder,
- multi-level AC-DC-AC drives,
- multi-drive applications,
- DC-AC drive with D-Q motor model and
- DC-AC drive with phase-domain motor.
- Finite element based motor models.

This training also presents important concepts related to real-time simulation:
- the importance of real-time interpolation techniques like RT-EVENTS and Time-Stamped Bridges
- the importance of advanced solvers like ARTEMIS
- the effects of the dead-time on the accuracy of the simulation,
- the effects of the time-step and the number of processors required versus applications.

This session will also presents the TestDrive Graphical User Interface environment used to experiments models and simulations.

The first studied system is composed of a 1000 MW (500 kV, 2 kA) HVDC link used to transmit power from a 500 kV, 5000 MVA, 60 Hz network to a 345 kV, 10 000 MVA, 50 Hz network (Figure 1). The rectifier and the inverter are 12-pulse converters. The rectifier and the inverter are interconnected through a 300 km distributed parameter line and two smoothing reactors. The RT-LAB simulator achieved a time step of 15 microseconds using the ARTEMIS toolbox and the RTE-Drive toolbox.

The second studied system highlights the capacity of RT-LAB XSG to make real-time simulation of complex plant models, composed of a PMSM and a IGBT PWM inverter, using an FPGA card. (Figure 2). The simulator achieved a very fast computation of the motor drive (e.g., latency of 250 nanoseconds) and allows very fast closed-loop testing of high-bandwidth of motors controllers.

The third studied system is a fuel-cell, hybrid-electrical vehicle drive, composed of a battery, a fuel cell (modeled as a voltage source), a DC-DC converter, and motor drive (Figure 3). In this system, the DC-DC converter controls the power sharing between the battery and the fuel cell. The simulator achieved time step below 25 microseconds.

The last presented system is a simulation of Finite-Element Analysis (FEA) model of Permanent Magnet Synchronous Motor (PMSM) drive directly on an FPGA card (Figure 4). The FEA model is computed from JMAG-RT software, from the Japanese Research Institute, while the FPGA drive model is designed using Xilinx System Generator. The complete model of the PMSM achieves an input-output latency of 240ns.
