Abstract

Thyristors-based converters are still today the most common type of HVDC links. Modular Multilevel Converter based HVDC links are often considered for lower power rating projects like off-shore wind farms. Both approaches present challenges in both the design and the testing of proposed circuit topologies and control & protection system design. Conventional real-time simulators used by most power electronic system manufacturers for testing thyristor-based AC-DC converter systems in HIL mode encounter difficulties or simply cannot simulate MMC-based circuits composed very large number of fast power electronic devices. This paper will demonstrate new solvers methods adapted for both thyristors and MMC-based HVDC links. In the case of thyristors-based HVDC, a new solver called State-Space Nodal implements an efficient real-time method to deal with the numerous switched filter banks and valves groups found in these apparatus. The real-time and parallel simulation of Modular Multilevel Converters with hundreds of switches, which is very difficult or impossible with conventional solvers, is made with a pragmatic fixed-causality solver. System transients and dynamic performance under several operating conditions evaluated in HIL mode with a prototype controller-in-the-loop composed of several hundred of I/O connections will also be presented, using the RT-LAB real-time digital simulator.

Abstract

This paper describes today's power system simulation challenge. Simulator technology has evolved from physical/analogue simulators (HVDC simulators, TNA’s) for electromagnetic transients and protection and control studies, to hybrid TNA/Analogue/Digital simulators with the capability of studying electro-mechanical transient behaviour [1], to fully digital real-time simulators. Today’s global power system infrastructure is rapidly changing towards increasingly distributed generation/distribution systems, and this transformation mandates expanded use of power electronic devices: HVDC, FACTS and interfacing devices for dc and variable-frequency power sources (photovoltaic, wind generation).

Abstract

Simulation tools have been widely used for the design and improvement of electrical systems since the midtwentieth century. The evolution of simulation tools has progressed in step with the evolution of computing technologies. In recent years, computing technologies have improved dramatically in performance and become widely available at a steadily decreasing cost. Consequently, simulation tools have also seen dramatic performance gains and steady cost decreases.Researchers and engineers now have access to affordable, high performance simulation tools that were previously too costprohibitive, except for the largest manufacturers and utilities. This paper introduces the role and advantages of using real-time simulation by answering three undamental questions: what is real-time simulation; why is it needed and where does it best fit.The recent evolution of real-time simulators is summarized. The importance of model validation, mixed use of real-time and offline modes of simulation and test coverage in complex systems is discussed.

Abstract

Real-time simulation requires the use of fixed step integration methods, capable of achieving accuracy with a time step range larger than 10 μs to 100 μs, to enable the use of standard processors and IO systems. Simulation accuracy increases when the time step value decrease but the processing power and number of processors increase when the time step decreases. The choice of integration techniques is also important. Simulation specialists must therefore select the best integration technique and time step that will yield to acceptable results. This document provides a comparison between simulation results obtained by using a classical 2nd order Tustin integration solver (also known as the Trapezoidal method) and the ARTEMIS 5th Order integration Method). The TUSTIN 2nd order method uses two terms of the Taylor series of the exponential function, while ARTEMIS 5th order uses five terms. Tustin is used by conventional electrical simulation software using the nodal technique such as PSCAD and EMTP while SimPowerSystems and eMEGAsim use ARTEMIS 5th order method in addition to the TUSTIN method.

Abstract

This paper discusses industrial applications of real time simulation technologies and opportunities that exist to include them in modern engineering education curricula. Real-time simulators are used extensively in many engineering fields. As a consequence, the inclusion of simulation applications in academic curricula can provide great value to the student. Statistical power grid protection tests, aircraft design and simulation, motor drive controller design methods and space robot integration are a few examples of real-time simulator technology applications to be discussed in this paper.

Abstract

This paper presents a modern PC-based real-time simulator using the latest INTEL quad-core processors to simulate a relatively large power system. The performance of the simulator is evaluated by comparing the results of different contingencies in two different simulation environments. A large grid model built using the EMTP-RV software and simulated in real-time using the eMEGAsim platform’s EMTP-RT software tool is described. Comparisons between the off-line and the Real-Time simulations are made using superimposed steady-state and fault condition waveforms.

Abstract

This paper describes a versatile, multi-domain, large power grid real-time digital simulator. Its ability to conduct multiple tests for protection coordination studies is described. A large grid model built using the EMTP-RV software and simulated in real-time using the eMEGAsim platform’s EMTP-RT software tool is described. A discussion and comparisons on the different solvers offered with both simulation environments are made. Comparisons between offline and Real-Time simulations are made using superimposed fault condition waveforms. Finally, multiple random tests are performed on the featured power system model and analyzed using the eMEGAsim simulator’s software package.
