Hydro-Québec Models Wind Power Plant Performance

“Accurate modeling is essential not only for planning investments but also to detect situations that can cause an outage. With MathWorks tools, we can simulate power electronics, mechanics, and control systems in one environment, and our models respond like the turbines we have in the field.” —Richard Gagnon, Hydro-Québec

Allegro MicroSystems Reduces Anti-Lock Braking System Sensor Development Time

“Using MathWorks tools, we identified the best algorithm choice. Because the model ran much faster than our circuit simulator, we caught implementation errors much quicker and shortened our time to market. Cor”y Voisine, Allegro MicroSystems

Description

Introduction

SimPowerSystems™ extends Simulink® with tools for modeling and simulating the generation, transmission, distribution, and consumption of electrical power. It provides models of many components used in these systems, including three-phase machines, electric drives, and libraries of application-specific models such as Flexible AC Transmission Systems (FACTS) and wind-power generation. Harmonic analysis, calculation of Total Harmonic Distortion (THD), load flow, and other key power system analyses are automated. SimPowerSystems models can be discretized to speed up simulations.

SimPowerSystems supports the development of complex, self-contained power systems, such as those in automobiles, aircraft, manufacturing plants, and power utility applications. You can combine SimPowerSystems with other MathWorks physical modeling products to model complex interactions in multidomain physical systems. The block libraries and simulation methods in SimPowerSystems were developed by Hydro-Québec of Montreal.
