The short-circuit response of a voltage source converter (VSC) can vary from each other significantly with different control strategies. This study investigates the performance of distance protection under unbalanced faults considering two control strategies during fault-ride-through using hardware-in-the-loop tests. Variations on fault type, converter current limit, fault resistance and pre-fault power flow conditions are also examined. The tests reveal that the error in measured impedance caused by fault resistance will be enlarged in a converter-dominated power system. The first control strategy tends to cause overreach problem while the second can raise both overreach and underreach problems. The indeterminacy associated with the second strategy is jointly affected by control parameters, converter current limit, fault resistance and pre-fault power flow conditions. The findings of this study can help to stipulate grid requirements under unbalanced faults.

Real-time test platform based on hardware-in-the-loop (HIL) simulation technology, troubleshooting for real-time problems such as interrupt latency and interface communication before physical testing, can effectively improve the traditional development process, shorten the research and development cycle, and reduce the cost and risk of test. Based on the technologies of virtual instrument, mathematical modelling, and HIL simulation, a real-time simulation framework combining the discrete-time converter system and the continuous-time motor system is proposed. Combined MATLAB/Simulink, dSPACE, and real-time hardware, an HIL real-time test platform is designed for the prototype and proper testing of the electrical control unit of more electric aircraft. The results and design principles of a three-stage brushless synchronous starter/generator system emulation using HIL simulation are presented.

In recent years, cyber-physical system (CPS) applications have been extensively utilised in the electric power grid to enable wide-area protection, control, and monitoring of power systems. Many of these applications in a smart grid CPS depend on reliable time synchronisation. For example, synchrophasor data from geographically distributed phasor measurement units (PMU) utilise global positioning system (GPS) for precise timing. However, these units are exposed to GPS time spoofing attacks that can lead to inaccurate monitoring and trigger unnecessary, and possibly destabilising, remedial control actions. The authors develop an end-to-end case study demonstrating the effect of GPS spoofing attacks on the phase angle monitoring and control functions of a PMU-based load shedding scheme. The evaluation of authors attack strategy is performed in a hardware-in-the-loop real-time digital simulator-enabled power system testbed.

hardware-in-the-loop (HiL) simulation is recognized as a reliable approach for testing and verification of the control systems of hybrid vehicles. To perform the HiL simulation, a real-time vehicle simulator is needed which can virtually emulate the real vehicle in communication with the control unit. This paper presents the design and implementation of a low-cost single PC based HiL simulation platform for testing of the Central Control Unit (CCU) in a series hybrid electric bus. For HiL simulation purposes, the generation and flow of the signals should be the same as those of the real system. Therefore, based on the Controller Area Network (CAN) messages and dynamic behaviour of each component, a comprehensive real-time simulator is designed in LabVIEW environment. The designed simulator together with the control unit and the necessary interfaces makes a functional low-cost HiL test bench. Due to modular simulation, subsystems of the designed simulator can be replaced by the real prototypes and this in turn leads to a more flexible HiL simulation test bench. With this system, the user can act like a real driver and experience driving regimes which may happen in reality without being involved with difficulties of testing on an actual vehicle. The designed simulation model has been validated using real test results. Using the designed test bench, the results show that all control functions in the CCU can be tested and verified.

The ongoing transition of low voltage (LV) power grids towards active systems requires novel evaluation and testing concepts, in particular for realistic testing of devices. Power hardware-in-the-loop (PHIL) evaluations are a promising approach for this purpose. This paper presents preliminary investigations addressing the systematic design of PHIL applications and their applicable stability mechanisms and gives a detailed review of the related work. A requirement analysis for emulation of grid situations demanding system services is given and the realization of a PHIL setup is demonstrated in a residential scenario, comprising a hybrid electrical energy storage system (HESS).

In this paper, design and analysis of interior permanent magnet synchronous motor for electric vehicle bus propulsion is performed based on Finite Element Method. As the increase of the advanced application which requires precise control, the inverter is regarded as requisite for controlling electric machines. In addition multi-domain co-simulation is important to consider the inter-linking effect of the system as well as the conventional sinusoidal input analysis to investigate the characteristics of electric machines, specifically. Therefore, Multi-domain co-simulation is performed to consider the effect of inverter current, containing time harmonics, to the characteristics of interior permanent magnet synchronous motor in system circumstance. Simulated result is validated by comparing it with experimental result. Lastly, virtual driving test using hardware-in-the-loop simulation is performed with co-simulated data to verify the reliability of multi-domain co-simulation model in virtual driving system.

This work presents a hydraulic anti-lock braking system (ABS) for a motorcycle. The ABS has a hydraulic modulator and an intelligent controller. The hydraulic modulator is analyzed, and then equipped on a scooter for road tests. The intelligent controller controls the hydraulic modulator by estimated vehicle velocity to calculate the slip ratio of the wheels in real time. The performance of the hydraulic modulator and intelligent controller are assessed by the hardware-in-the-loop (HIL) simulations and road tests. In HIL simulation, the ABS is tested for different initial braking velocities on roads with different adhesive coefficients. Furthermore, both HIL simulations and road tests are conducted on a one-phase pavement road and three-phase pavement road.

The Flight Control Switching Mechanism System (FCSWMS) can give a pilot-selectable research control law capability due to the Research Flight Control Computer (RFCC) and the basis triplex Primary Flight Control Computer (PFCC), therefore this system provides a flexible platform for control law algorithm research. The Research Flight Control System (RFCS) supports a design capability for relatively fast control law modifications and development, while retaining safety of flight through the PFCC. The RFCS processor was designed by more improved performance than primary FCC processor for the implementation of switching algorithm on the FCSWMS. The application software based on VxWorks operating system was developed on the tornado development environment. The verification and validation of research flight control computer system and software was performed in the hardware-in-the loop simulation environment including the primary Right control computer, cockpit and etc.. The RFCS verified through the software and system test will be useful for a variety of advanced control law research and future flight control system development.
