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.

Abstract

This paper describes the RT-LAB real-time simulator implementation of the Hardware-In-the-Loop simulation of a fuel cell hybrid electric vehicle system with several 10 kHz converters. The paper demonstrates the necessity to use special IGBT bridge models that implements interpolation techniques within fixed time step simulation scheme. The paper reports on the latest advances from Opal-RT to simulate this kind of system with a 10 µs sample time.

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.

The software, named ARTEMIS accurately simulates time-segment linear systems with discontinuities occurring anywhere between time-steps. This paper focuses on the simulation of a thyristor-controlled reactor by the ARTEMIS DTCSE (Discrete Time Compensation of Switching Events) algorithm and the RT-EVENTS algorithm, showing the accuracy of the software.

The software, named ARTEMIS (Advanced Real-Time Electro-Mechanical Transient Simulator), accurately simulates time-segment linear systems with discontinuities occurring anywhere between time-steps. The new software is used for the simulation of energy and power system dynamics, and is implemented in the ARTEMIS Add-On for Simulink’s Power System Blockset. With ARTEMIS’ Discrete Time Compensation of Switching Events (DTCSE) and RT-EVENTS algorithm, the intra-step events are transparently taken into account and compensated for in the simulation results.
