Opal-RT eDRIVEsim Real-time Simulation Platform

Opal-RT eDRIVEsim is a real-time platform for designing advanced control systems and performing HIL testing of controllers used in high-speed electric motors, power converters, and hybrid drives. eDRIVEsim’s software is based upon Opal RT’s RT-LAB real-time technology for model-based designs. RT-LAB’s flexibility and scalability allow it to be used in virtually any simulation or control system application, and to add computing-power where and when it is needed.

eDRIVEsim uses Simulink(R) as a front-end graphical modeling environment, and comes with a full range of software tools and libraries for the real-time modeling and simulation of power converters and motor drives. In addition, eDRIVEsim uses the latest Intel(R) multi-core X86 processors and Opal-RT’s OP5000 series of high speed Xilinx(R) -based FPGA I/O products as real-time targets, and is available in a 19-inch rack desk-side rack-mountable chassis or in a compact MX STATION portable chassis.

eDRIVEsim is designed to conduct controller testing and HIL simulation of various electric and power electronic systems including:

  • PMSM, BLDC, and IM motor drives
  • Automotive: Hybrid power trains, power steering, and auxiliary power systems
  • Transportation: Trains traction and auxiliary systems, ship propulsion systems
  • Rectifiers and battery chargers
  • Wind energy and power electronic distributed generation and distribution systems
  • Industrial drives and multi-level converters

eDRIVEsim can also be used for fast power electronic control prototyping; implementing control algorithms and testing them in real-time and in both digital mode or HIL mode, by connecting the prototyped controller I/Os to either a virtual plant or a real-plant. The eDRIVEsim OP4130′s Quad-core processor enables the simulation of complex multi-drive systems.

Using eDRIVEsim OP4110 and OP4130, typical AC motor drives, including the motor and a 6-switch inverter, can be simulated at a time step in the range of 10-20 microseconds, depending on the model characteristics and I/O used. This makes these eDRIVEsim configurations ideal for testing motor drives with a switching frequency up to 10 kHz, and a rotation speed up to 6000 RPM. Using Opal-RT’s OP5130 FPGA board, eDRIVEsim 4120 can achieve total input-output latency below 1.5 microseconds by executing models on the FPGA chip. The OP4120 can simulate PWM frequency exceeding 100 kHz, and a rotation speed up above 20000 RPM with JMAG finite-element based models.

With the eDRIVEsim OP4130, multiple drives and other power converters can be simulated simultaneously by taking advantage of all four processing cores of the INTEL QUAD-CORE 2.4-GHz processor.

eDRIVESim also allows the engineer to easily develop the circuit of an application (motor drive, power conversion system) in Simulink(R), with basic components taken from different libraries. Blocks from Opal-RT’s specialized modeling libraries RTeDrive(TM), RT-Events(TM) and ARTEMIS(TM) (with SimPowerSystems(R)) can be included in the Simulink model to run on the CPU real-time target.

After compilation, the Simulink part of the model is downloaded to the Intel(R) Core(TM) 2 Duo or Quad processor, while the Xilinx part is downloaded to the eDRIVEsim OP4120′s Opal RT OP5130 FPGA chip. The resulting real-time target is ready to be connected to the physical equipment to be controlled or tested, by the means of analog and digital I/Os.

Models can be connected to external equipment simply by dragging-and-dropping any input or output needed from the extensive list of I/O blocks available in the RT-LAB I/O library.

With eDRIVEsim OP4120, subsystems designed with blocks from the Xilinx Blockset for Simulink can be incorporated into a model, allowing that part of the model to be executed on a Opal RT OP5130 Xilinx FPGA chip, achieving low latency unprecedented in the simulation of high speed motors and high switching frequency converters, and allowing testing of fast controllers and protection systems.
