What Is the Power System Blockset
Electrical power systems are combinations of electrical circuits, and electro-mechanical devices, like motors and generators. Engineers working in this discipline are constantly asked to improve the performance of the systems. Requirements for drastically increased efficiency have forced power system designers to use power electronic devices and sophisticated control system concepts that tax traditional analysis tools and techniques. Further complicating the analyst's role is the fact that the system is often so nonlinear, the only way to understand it is through simulation.
Land-based power generation from hydroelectric, steam, or other devices, is not the only use of power systems. A common attribute of these systems is their use of power electronics and control systems to achieve their performance objectives.
The Power System Blockset was designed to provide a modern design tool that will allow scientists and engineers to rapidly and easily build models that simulate power systems. The blockset uses the Simulink® environment, allowing a model to be built using simple click and drag procedures. Not only can the circuit topology be drawn rapidly, but the analysis of the circuit can include its interactions with mechanical, thermal, control, and other disciplines. This is possible because all of the electrical parts of the simulation interact with Simulink's extensive modeling library. Since Simulink uses MATLAB® as the computational engine, MATLAB's toolboxes can also be used by the designer.
Users will find that the blockset can be rapidly put to work. The libraries contain models of typical power equipment such as transformers, lines, machines, and power electronics. These models are proven ones coming from textbooks, and their validity is based on the experience of the Power Systems Testing and Simulation Laboratory of Hydro-Quebec, a large North American utility located in Canada. The capabilities of the blockset for modeling a typical electrical grid are illustrated in demonstration files. And for the users who want to refresh their knowledge of power system theory, there are also self-learning case studies.
