Abstract

This paper explains a real-time simulator configured for the testing of Permanent Magnet Synchronous Motor Drives, Switched Reluctance Motor Drives and Induction Motor Drives along with the associated power electronics, like boost and buck converters. The technology is based on FPGA and is coded in a way that a unique bitstream can be used for all power electronic topology and parameters, therefore avoiding the typically very long compilation time of modern FPGAs. This paper highlights one such solver called eHS that enables test engineers to model user-defined power electronic topologies and simulate them on the real-time simulator in a matter of minutes.

Abstract

This paper presents an FPGA test system composed of an Induction Machine (IM), configurable as a Doubly-Fed Induction Machine (DFIM) or squirrel-cage induction machine, along with power electronic models suitable for virtual motor drive control development. The IM model is designed so that all parameters can be modified online. The power electronic part is customizable using a variable topology FPGA solver called Electric Hardware Solver (eHS). The system is designed for fast design iteration process by allowing circuit and parameter modification with a unique bitstream. The system allows control engineers to validate production controllers in real-time using a virtual IM.

Abstract

The ePHASORsim tool offers real-time phasor domain simulations for large-scale power systems. Applications include contingency studies, testing control devices, operator training, and SCADA system tests. This paper describes a new application of this tool for Model-In-the-Loop simulations. Two test experiments are shown in this paper to demonstrate the accuracy and advantages of utilizing ePHASORsim for this purpose. The Matlab SimPowerSystems® toolbox is used to validate the results.

Abstract

Chapter 18: Real-time Simulation of Modular Multilevel Converters (MMCs) Real-time offers several advantages to speed up the development of new product. One of these advantages being the possibility to test and develop controllers when the hardware is not yet available. This is a serious advantage in the case of high-order multilevel converter, like modular multilevel converter (MMC) topology. Its physical size could raise serious issues for most laboratories, without even mentioning the cost to build such a complex structure. It can also be useful to analyze the interaction between several MMCs and conventional high-voltage DC (HVDC) systems installed on the same power grid. Furthermore, it can perform factory acceptance test of the control system before the installation in the field. Nowadays, real-time simulators are often used simply to accelerate simulations, which could take several hours for simulation runs of a few seconds with a power grid having tow or three converter stations using conventional single-processor simulation software. This chapter introduces bases of real-time simulation: its advatanges and its constraints. Using these bases, real simulation of an MMC will be undertaken. This topology is made of many identical cells connected in series. Its modularity makes it suitable for various applications from medium voltage in a drive system using only a few cells to a large HVDC transmission system containing a wide range of cells. Connecting many of these cells in series reduces the voltage level that each sustains, decreasing the price of each components, reducing the switching losses and smaller and smaller dV/dt at its AC bus, while producing a sinusoidal waveform with a very low total harmonic distortion (THD) eliminating the use of bulky reactive component filter.

Abstract

Since Modular Multilevel Converters (MMC) have a sophisticated control, the real time simulation platform becomes critical for hardware-in-the-loop (HIL) test of the actual controllers in various scenarios before commissioning. This paper presents a multi-rate real time simulator that is able to simulate electromagnetic transients of MMC systems and connect to industrial controllers through fiber optics and copper wires for HIL tests. The MMC is implemented in field-programmable gate array (FPGA) with a sub-μs time step and the rest of the power system is simulated in the central processing unit (CPU) with a time step of 10~50 μs. Input and output (I/O) drivers are implemented in the same FPGA for a fast-rate and low-latency communication. Each FPGA accommodates up to 1530 sub-modules (SM), and multiple FPGA connected to one simulator can simulate MMC with more SM and multi-MMC systems. The performance is demonstrated in a 1500-SM MMC study case.

Abstract

In this paper, we review state-of-the-art solvers and techniques applicable to HIL simulation of power systems, power electronics and motor drives. These methods can be distinguished by the applications as well as the computational hardware engines used. Industrially speaking, there are two main types of hardware used today to make HIL: multi-core CPUs and FPGAs. Other promising technologies like, GPU (and similar approaches such as Intel 100 cores ‘ Xeon phi’ co-processors), are also possible and rather similar to multi-CPU approach but not discussed in this paper .

Abstract

Transmission and distribution systems are becoming increasingly complex due to the integration of renewable energy and high-performance control and special protection systems. Sophisticated tools are required to evaluate the performance and reliability of several fast local protection and control systems that interact with slower wide-area control and protection systems that increase performance and security, prior to deployment. In particular, these tools must allow the testing of actual protection and control systems hardware units by connecting them to high-fidelity simulations of power systems that integrate several validated protection and control systems. OPAL-RT will demonstrate how fast electromagnetic simulation tools, with reaction times smaller than one microsecond, can be integrated with transient dynamic simulation tools, using Phasor-mode simulation with time steps as large as 10 milliseconds, to analyze the complex dynamics of very large transmission and unbalanced distribution systems. The same hardware-in-the loop simulation technology can also be used to design and test new control and protection algorithms, as well to identify models of black box systems, to evaluate the global performance of modern power systems.

Abstract

This paper explains the users’ custom model feature of the State-Space-Nodal (SSN) solver of ARTEMiS. Using this feature, users can interface directly with the SSN nodal solver their own discretized models. This can lead to great improvements in real-time performance with some models that exhibit many different operation modes and/or models having a high degree of internal redundancy. Direct discretized solver coding also enables the user to write custom stabilization code or to use different solvers coupled in the same nodal admittance matrix. On-Load Tap Changer (OLTC) transformer, Modular Multilevel Converter (MMC) and frequency dependent line models (modal and phase domain types) are given as examples.
