Abstract: Simulation of complex systems usually requires that heterogeneous models be integrated into a single simulation environment. Because these models are often developed by different teams, or depend on various commercial simulation tools (such as SimulinkTM, DymolaTM or SystemBuildTM), considerable effort is expended in configuring the corresponding components into a cohesive co-simulation. As part of its research and development efforts, Opal-RT has developed RT-LAB Orchestra, a software application that facilitates integration and interoperability between co-simulation components. RT-LAB Orchestra is an application-level data communication layer that sits on top of Opal-RT’s RTLAB framework, a proven real-time architecture for distributed simulations.

Abstract: Nowadays, it is a common engineering practice to test a motor controller against a simulated motor model running in real-time before using the controller in real-life conditions. This has several advantages. For example, the simulated motor can be tested with borderline conditions that would damage a real motor, sometimes a costly prototype. The motor itself may be under development in parallel to the controller and therefore may not even be available. The controller is interfaced with the real-time simulated motor through a set of proper I/Os; this is called Hardware-In-the-Loop (HIL) simulation.

Abstract: This paper presents a new development in the field of design process and testing of motor drives, for hardware-in-the-loop (HIL) applications.

The paper describes the integration of FE-based motor model generated by JMAG® software, with the high-end real-time RT-LAB® simulator. The complete solution consists of combining accurate FE-based motor model, with inverter model, including important switching parameters, all constructed in the Simulink® environment, and simulated on PC-based RT-LAB simulation platform, using ultra-fast processors and FPGA-based inputs/outputs (I/O) boards. By connecting the real-time simulator to an external controller under test, this allows high fidelity HIL simulation of motor drives and enables the design engineers to test the system and the controller with a very accurate, FE-based motor model running in real-time.

A solution to the problems of long simulation times and inaccurate simulations is to combine the use of the RT-EVENTS Blockset, which works with the SIMULINK™ graphical software, at the engine modeling stage with the RT-LAB software for the distribution of the simulations on a cluster of microprocessors and for the control and monitoring of the simulations.

Abstract: This paper presents a real-time simulator of a permanent magnet synchronous motor (PMSM) drive based on a finite-element analysis (FEA) method and implemented on an FPGA card for HIL testing of motor drive controllers. The proposed PMSM model is a phase domain model with inductances and flux profiles computed from the JMAG-RT finite element analysis software. A 3-phase IGBT inverter drives the PMSM machine. Both models are implemented on an FPGA chip, with no VHDL coding, using the RT-LAB real-time simulation platform from Opal-RT and a Simulink blockset called Xilinx System Generator (XSG). The PMSM drive, along with an open-loop test source for the pulse width modulation, is coded for an FPGA card. The PMSM drive is completed with various encoder models (quadrature, Hall effects and resolver). The overall model compilation and simulation is entirely automated by RT-LAB. The drive is designed to run in a closed loop with a HIL-interfaced controller connected to the I/O of the real-time simulator. The PMSM drive model runs with an equivalent 10 nanosecond time step (100 MHz FPGA card) and has a latency of 300 ns (PMSM machine and inverter) with the exception of the FEA-computed inductance matrix routines which are updated in parallel on a CPU of the real-time simulator at a 40 us rate. The motor drive is directly connected to digital inputs and analog outputs with 1 microsecond settling time on the FPGA card and has a resulting total hardware-in-the-loop latency of 1.3 microseconds.

Abstract: Nowadays, it is a common engineering practice to test a motor controller against a simulated motor model running in real-time before using the controller in real-life conditions. This has several advantages. For example, the simulated motor can be tested with borderline conditions that would damage a real motor, sometimes a costly prototype. The motor itself may be under development in parallel to the controller and therefore may not even be available. The controller is interfaced with the real-time simulated motor through a set of proper I/Os; this is called Hardware-In-the-Loop (HIL) simulation.

Abstract: This paper presents the RT-LAB Electrical Drive Simulator technology along with practical applications. The RT-LAB simulation software enables the parallel simulation of power drives and electric circuits on clusters of PC running QNX or RT-Linux operating systems at sample time below 10 μs. Using standard Simulink models including SimPowerSystems models, RT-LAB build computation and communication tasks necessary to make parallel simulation of electrical systems with standard off-the-shelf PCs and communication links like InfiniBand.

For power drives with even higher bandwidth, RT-LAB XSG permits simulation of PMSM drive at 1 μs on FPGA with VHDL code generated from Xilinx System Generator.

Abstract: This paper presents technologies designed for Hardware-In-the-Loop testing of modern motor drive systems commonly found in electric vehicles. Deliverable with the RT-LAB simulator comes various motor drive models with different precisions and complexities, from the basic Park two-axis machine models to detailed Finite-Element-Analysis based models. The former is more rapid while the latter is more precise. These models can be implemented on different hardwares, CPU or FPGA. CPU-based implementation rely on well-known ‘C’ code generation techniques and is rather flexible. FPGA implementation breaks through common limitations of CPU-based implementation by allowing much faster analog output rates, higher PWM frequencies and smaller model latencies. An FPGA implementation also allows the user to model fast protection schemes found on commercial drives (ex: over-current protections).

Abstract: This paper compares the performances achieved with the conventional digital redesign techniques with those obtained with the modern global digital redesign methods such as the plant input mapping methods and the optimal digital redesign approach.

Abstract: In this paper, we detail the real-time simulation results of a medium-sized network composed of 8 synchronous machines and an HVDC link. The model is composed of two Kundur-like 4 machines networks connected together with a 12-pulse HVDC link. The complete network is modeled with SimPowerSystems with ARTEMIS real-time plug-in and is simulated in real-time on a RT-LAB InfiniBand PC-cluster composed of 3 dual-CPU dual-core Opteron PCs. The network model includes the HVDC control and protection systems as well as the synchronous machine regulators and power stabilizers. It also includes typical fault simulation capability like HVDC DC faults, thyristor misfires and AC faults. This model is excellent to study the complex interactions between an HVDC link and AC network under normal and transient conditions. The real-time simulation is controlled and monitored with a TestDrive interface from Opal-RT. This interface, based on LabView, permits easy monitoring and control of the complete system and enables Python-based scripting for automated tests. The proposed simulator can be interfaced with external equipments and controllers by direct reconfiguration of a FPGA I/O card with Xilinx System Generator blockset.

Abstract: The modeled system, shown in the figure below, is composed of two generation-groups and five induction-machine drive loads interconnected by a DC bus. Each generation-group includes four ideal sources behind R-L circuits rated 230V at a frequency of 60Hz. The AC voltage provided by each generator is rectified by a 6-pulse ideal diode rectifier with R-C snubbers and is isolated using a Yg-Y transformer of unary windings ratio. The diode rectifier that is used is the SPS Universal bridge model. Short decoupling lines (stublines) are essential for real-time performances as it produces decoupling of the underlying computational models. In order to lighten the calculation load of the two CPUs assigned to the generation groups, the system is decoupled by one stubline at the end of each rectifier.
