“…The principle real-time simulator is an RTDS system (RTDS Technologies, Inc.), described in [13]. The power-system simulator at CAPS contains more than 100 RISC processors, and is designed for transient simulations of systems that could contain up to 1000 electrical nodes using time-step sizes on the order of 50 s. For fast-switching power electronics sub-systems, the RTDS can dedicate a processor to simulate such subsystems with smaller time-steps (typically 2 s).…”

The recent development of modular multilevel converters (MMC) provides new opportunities for medium voltage DC (MVDC) systems for all electric ship design and offshore wind parks. Therefore, the Center for Advanced Power Systems at Florida State University has recently commissioned a new MVDC power-hardware-in-the-loop laboratory rated at 5 MW at DC voltages between 6…24 kV. The new lab features four individual MMCs, each composed of 36 full-bridge cells, and capable of delivering 210 A at 0…6 kV. This paper describes the entire system in detail, including the advanced current and voltage control concepts along with the state of the art digital control hardware. Selected commissioning results demonstrate the performance of the system under dynamic conditions and provide comparison with simulations obtained from a corresponding controller hardware-in-the-loop setup which is also described in the paper.Keywords-modular multilevel converter, medium voltage DC, shipboard power system, hardware-in-the-loop, fault management

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.

In this paper is described the implementation of the frequency-dependent line model (FD-Line) in a real-time digital power system simulator. The main goal with such development is to describe a general procedure to incorporate new realistic models of power system components in modern real-time simulators based on the Electromagnetic Transients Program (EMTP). In this procedure are described, firstly, the steps to obtain the time domain solution of the differential equations that models the electromagnetic behavior in multi-phase transmission lines with frequency dependent parameters. After, the algorithmic solution of the FD-Line model is implemented in Simulink environment, through an S-function programmed in C language, for running off-line simulations of electromagnetic transients. This implementation allows the free assembling of the FD-Line model with any element of the Power System Blockset library and also, it can be used to build any network topology. The main advantage of having a power network built in Simulink is that can be executed in real-time by means of the commercial eMEGAsim simulator. Finally, several simulation cases are presented to validate the accuracy and the real-time performance of the FD-Line model. Keywords:Real-Time Simulators, EMTP program, frequency-dependent line model, FD-Line, Simulink, power-system blockset. RESUMENEn este artículo se describe la implementación del modelo de línea dependiente de la frecuencia FD-Line en un simulador digital en tiempo-real de sistemas eléctricos de potencia. El objetivo principal con este desarrollo es describir un procedimiento general para incorporar nuevos modelos realistas de componentes de sistemas eléctricos de potencia en los modernos simuladores de tiempo real basados en el programa de transitorios electromagnéticos (o EMTP, por sus siglas en inglés). En dicho procedimiento se describen, primeramente, los pasos para obtener la solución en el dominio del tiempo de las ecuaciones diferenciales que modelan el comportamiento electromagnético de una línea de transmisión polifásica con parámetros dependientes de la frecuencia. Posteriormente, se implementa la solución algorítmica del modelo de línea en Simulink, por medio de una función S en lenguaje C, para ejecutar simulaciones fuera de línea de transitorios electromagnéticos. Esta implementación permite ensamblar libremente el modelo FD-Line con cualquier elemento de la librería de sistemas de potencia en Simulink y también, se puede construir cualquier topología de red eléctrica. La principal ventaja de tener una red eléctrica construida en Simulink es que puede ser ejecutada en tiempo real por medio del simulador comercial eMEGAsim. Finalmente, se presentan varios casos de simulación de sistemas de potencia para probar la precisión y el desempeño en tiempo-real del modelo FD-Line.Palabras clave: Simulador tiempo real, programa EMTP, modelo de línea dependiente de la frecuencia, FD-Line, Simulink, librería de sistemas eléctricos de potencia.
