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

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 presents a real-time simulator for large power network based on Custom-Of-The-Shelf technologies, all embedded in the RT-LAB real-time simulation platform. This platform uses Pentium, Xeon, Opteron-based PCs (multi-CPUs and/or dual-core configurations) or even Xilinx FPGA cards for computational engines and InfiniBand communication fabric for fast inter-PCs communications. The real-time PCs runs under well-known operating systems QNX or RedHawk Linux while the main user control interface is either Simulink or LabView. The paper demonstrates the real-time simulation of complete single-pole 12-pulse HVDC system on dual-CPU, dual-core 2.2 GHz Opteron PC under 15 microseconds time step. It also demonstrates the real-time simulation of complex power system devices like SVC, STATCOM and more general power systems like the Kundur network.

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. To accommodate the high bandwidth of electrical systems, the RT-LAB Electrical Drive Simulator comes with special Simulink-based modeling tools, namely ARTEMIS and RT-Events that permits real-time simulation of electrical systems at practical time step of 10 μs but with sub-μs equivalent precision through the use of interpolation techniques. 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 a new development in the field of design process and testing of motor drives, for hardware-in-the-loop (HIL) applications. It consists of implementing the Finite Element (FE) Method applied to electric motors on a real-time simulator; coupled with circuit simulation, this enables accurate real-time simulation of the complete motor drive, including the inverter and the motor. 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.

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

This paper presents a set of novel tools that allow the efficient simulation, at fixed time steps, of event-based dynamic systems. The so-called RT-EVENTS library is an innovative toolbox that can be used with the SIMULINK graphical software and that solves the following two problems encountered in the simulations of event-based systems: (1) time consuming variable-step algorithms; and (2) inaccurate real-time simulations with fixed-step algorithms.
