Abstract

To meet the growing demand for integration of renewable energy sources onto today’s power grids, many engineers from different specialized fields must be involved since various types of studies need to be conducted. The integration of distributed generation (DG) sources significantly changes the characteristics of an entire network. Such interconnection projects will require analysis of power quality, transient response to fault occurrences, protection coordination studies and controller interaction studies. The first considerable challenge is related to power electronic converters, which are increasing in number and found on most DG sources. Accurately simulating fast switching devices requires the use of very small time steps to solve the system’s equations. Off-line simulation is widely used in the field, but it is time consuming if no precision compromise has been made on models (i.e. the use of average models). Moreover, off-line simulation tools do not offer the wide range of possibilities available with state-of-the-art distributed real-time simulators. Such tools combine, for instance, the efforts of control engineers and specialists from wind turbine manufacturers, who need to test their controllers using hardware-in-the-loop (HIL), together with those of network planning engineers from public utilities, who will conduct interconnection, interaction and protection studies. The eMEGAsim simulation platform is fully integrated with Simulink/SimPowerSystems (SPS) from The MathWorks and EMTP-RV. This makes eMEGAsim a valuable solution for engineers who already have models built with these off-line simulation applications, as well as for less experienced users. This paper focuses on the prototyping and testing of DG controllers using hardware-in-the-loop simulation. The model described in this paper is a 10-turbine wind farm connected to a single feeder, simulated using an eMEGAsim real-time simulator equipped with 8-processor cores. One of the wind turbines is controlled using an externally emulated controller. The emulated controller model consists of a replica of all other wind turbine controllers, which are locally simulated in the plant model. It is modeled and simulated using a dual-processor core real-time simulator, which interacts with the plant model via analog and fast digital inputs and outputs. This paper validates the proposed real-time simulator for the study of wind-farm electromagnetic disturbance studies with HIL-connected DFIG controllers, specifically that the simulator can be interfaced with high-frequency PWM controllers without distortions caused by the sampling time of the simulator.

Abstract

Today, the development and integration of train and ship controllers is a more difficult task than ever. Emergence of high-power switching devices has enabled the development of new solutions with improved controllability and efficiency. It has also increased the necessity for more stringent test and integration capabilities since these new topologies come with less design experience on the part of the system designers. To address this issue, a real-time simulator can be a very useful tool to test, validate and integrate the various subsystems of modern rail vehicle devices. This paper presents such a real-time simulator, based on commercial-off-the-shelf PC technology, suitable for the simulation of train and ship propulsion devices. The requirements for rail/water vehicle test and integration reaches several levels on the control hierarchy from low-level power electronic converters used for propulsion and auxiliary systems to high-level supervisory controls. This paper places great emphasis on the real-time simulation of several high-power drives used for train and ship propulsion, including a multi-induction machine drive, a three-level GTO - PMSM drive and a high-power thyristor-based converter - synchronous machine drive. All models are designed first with the SimPowerSystems blockset and then automatically compiled and run on commercial PCs under RT-LAB. Interfaces to I/O are also made at the Simulink model level without any low-level coding required by the user. Supervisory control integration and testing can also be made using the RT-LAB real-time simulator. The other objective of this paper is to demonstrate that HIL testing of complex drives, such as the those found on trains, can be done using commercial-off-the-shelf (COTS) software and hardware and model-based design techniques that only require high-level system models suitable for system specifications down to controller test and final system integration.

Abstract

Presented in this paper are the results of closed-loop control experiments using a virtual permanent magnet synchronous motor (PMSM) drive implemented on a fieldprogrammable gate array (FPGA) card connected to an external controller. The FPGA-based PMSM motor drive is implemented on an eDRIVEsim simulator, based on the RT-LAB platform. The eDRIVEsim simulator implements 2 types of motor drive models, Park (d-q) and Finite Element Analysis (FEA), on an FPGA card of the simulator. The FPGA-based motor model is designed with Xilinx System Generator (XSG) blockset with no HDL hand coding. Both motor models compute motor currents using a phase-domain algorithm solver that can take into account the instantaneous variation of inductance and non-sinusoidal induced voltage. The FEA-type model uses inductance and Back-EMF profiles computed with JMAG-RT. The d-q model uses sinusoidal induced Back-EMF voltage and phase inductance values computed from Ld and Lq using the well-known Park transformation. A 3-phase IGBT inverter implemented in the FPGA chip drives the PMSM machine. The PWM controller is designed using Rapid Control Prototyping (RCP) methodology based on Simulink. It is implemented on an separate RT-LAB system using standard Opal-RT FPGA-based I/O cards for Analog Input capture and PWM generation. The paper presents results from the closed-loop control of the PMSM drive in both current control and speed control modes and discusses the advantages of using such a virtual test bench for motor drives.

Abstract

This application note reports how the TUSTIN method in PSB and the ART5 method in the ARTEMIS Add-On compare in terms of precision, particularly for long-term simulation. The ARTEMIS Add-On uses the ART5 method and the ‘Zero hold for input’ option is not checked.

Abstract

This application note explains a two areas, four machines power system is considered in this note in order to demonstrate numerical advantages of ARTEMIS’ fixed-step-size integration method versus Tustin method currently used by power system simulators such as Power System Blockset (PSB). Proposed methods are also compared to the variable step solver, which is supposed to give the closest response to the actual system’s one.

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 an electrical circuit 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 effectively make parallel simulation of electrical systems with low cost off-the-shelf PC technology. 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.
