“…The experiment is respectively carried out on the single-phase PWM inverter and the current-type LPA of a general-purpose relay testing device, and for comparison they are both used to re-produce the same fault current that is recorded by the digital fault recorder. It is necessary to point out here that reproducing the fault current/voltage is a novel and important function of the modern relay testing device, which can provide the relay or automation equipment under test with "real" fault signals [18][19][20]. And, the fault current shown in Figure 4(a) is taken as an example for reproducing.…”

Abstract-P and PI control methods are widely used in the closed-loop control of the inverters in various power electronic equipment. However, PID control method is barely adopted. In this paper, from an in-depth analysis of the operation and control processes of pulse width modulation (PWM) inverter, it is verified that PID control method is not suitable for inverter control. And the theoretical process gives birth to a new control method, which is similar but not identical to PID control method, therefore, it is named as pseudo-PID control method. For fundamentality and generality, the pseudo-PID control method is derived from the single-phase PWM inverter, which is the basis of threephase or multilevel inverters. To verify the performance of the pseudo-PID control method, it is applied to a single-phase PWM inverter for relay testing. The simulation and experimental results demonstrate that with the aid of pseudo-PID control method the accuracy of the output current of the inverter is already comparable to that of the linear power amplifier (LPA), which makes the application of inverter in relay testing feasible. Considering the higher efficiency and simpler structure of the PWM inverter, it can make the relay testing device more cost-effective.

“…It performs the connection of an actual power device or system (the Hardware under Test (HuT)) to a real-life system which is simulated in a Digital Real-Time Simulator (DRTS), allowing repeatable and economical testing under realistic, highly flexible and scalable conditions [23]. Extreme conditions can be studied with minimum cost and risk, while problematic issues in the equipment behaviour can be revealed allowing an in depth understanding of the tested device.…”

“…It is particularly suitable for studying the integration of new components in distribution grids, as physical photovoltaic generators, wind turbines, electric vehicles, energy storages, or whole microgrids. It can be connected to a simulated active network, containing various simulated DER devices, where complex interactions can be identified [21,23,24]. However, PHIL is mainly used for testing of single components.…”

Renewable energy sources are key enablers to decrease greenhouse gas emissions and to cope with the anthropogenic global warming. Their intermittent behaviour and limited storage capabilities present challenges to power system operators in maintaining the high level of power quality and reliability. However, the increased availability of advanced automation and communication technologies has provided new intelligent solutions to face these challenges. Previous work has presented various new methods to operate highly interconnected power grids with corresponding components in a more effective way. As a consequence of these developments the traditional power system is transformed into a cyber-physical system, a smart grid.Previous and ongoing research activities have mainly focused on validating certain aspects of smart grids, but until now no integrated approach for analysing and evaluating complex configurations in a cyber-physical systems manner is available. This paper tackles this issue and addresses system validation approaches for smart grids. Different approaches for different stages in the design, development, and roll-out phase of smart grid solutions and components are discussed. Finally, future research directions are analysed.Keywords: smart grid; simulation; hardware-in-the-loop; research; infrastructure; education; training IntroductionEnergy efficiency and low-carbon technologies are key enablers to mitigate the increasing emission of green-house gases still resulting in a global warming trend [1]. The efforts to reduce greenhouse gas emissions also strongly affect the power system. Renewable sources, storage systems and flexible loads provide enhanced possibilities but power system operators and utilities have to cope with their fluctuating nature, limited storage capabilities and the typically higher complexity of the whole infrastructure with a growing amount of heterogeneous components [2]. Additionally, due to changing framework conditions, like the liberalization of the energy markets and new regulatory rules, as well as technology developments (e.g., new components), approaches for design, planning, and operation of the future electric energy system have to be restructured. Sophisticated component design methods, intelligent information and communication architectures, automation and control concepts as well as proper standards are necessary in order to manage the higher complexity of such intelligent power systems (i.e., smart grids) [3][4][5]. Besides technical challenges also economic, ecological and social issues have to be addressed in smart grid research and innovation, too.During the last decade-especially in the past framework programs of the European Commission (i.e., FP6 and FP7)-a growing number of research and technology development activities have already been carried out in this area. Their main attempt was to fulfil the challenging goals and needs of the Strategic Energy Technology Plan (SET-Plan) of the European Commission for a sustainable environment and to foster the inno...

“…Since its beginning in the 1950s, the time-domain digital simulation of electromagnetic transients in power systems [1] has evolved to the present-day real-time simulators that can interact with real equipment through hardware-in-the-loop (HiL) digital real-time simulation (DRTS) [2]. This has become possible because simulators can resolve the differential equation system that represents the power system dynamics in a shorter time than the duration of the physical phenomenon [3].…”

PC Implementation of a Real-Time Simulator Using ATP Foreign Models and a Sound Card

This work reports the personal computer implementation of a real-time simulator based on the widely used Electromagnetic Transients Program, version Alternative Transients Program (EMTP-ATP) software for testing protection and control devices. The proposed simulator was implemented on a conventional PC with a GNU/Linux operative system including a real-time kernel. Using foreign models programmed in C, ATP was recompiled with the PortAudio (sound card I/O library) with tools for writing and reading the parallel port. In this way, the sound card was used as a digital-to-analog converter to generate voltage waveform outputs at each simulation time step of the ATP, and the parallel port was used for digital inputs and outputs, resulting in a real-time simulator that can interact with protection and control devices by means of hardware-in-the-loop tests. This work uses the minimum possible hardware requirements to try to implement a real-time simulator. Due to the limitation of two channels, this simulator was used mainly to demonstrate the implementation methodology concept at this stage; this concept could potentially be expanded with more powerful hardware to improve its performance. The performance of the implemented simulator was analyzed through interactions with a real intelligent electronic device (IED). Furthermore, a comparison with the results obtained by means of the well-known real-time digital simulator (RTDS) was presented and discussed.
