The paper introduces an effective toolbox for engineers, researchers and students to design and study electric drives. The described package eDrive includes a database of motors, power converters, and gears, an object-oriented simulator, a virtual signal generator, the module of the torque/current, speed, and path controllers, as well as the suitable visual interface. The system provides for the development,...
Some modelling methods and associated tools are presented in this paper to efficiently and accurately simulate the electromagnetic behaviour of power electronic structures. Moreover, as engineers have to face new challenges, the synergy between simulation tools is illustrated as a possible solution for addressing this "multiphysic" topic. The article is also pictured of several application...
The paper presents the topology and functioning of the model-based laboratory system to study the power electronic converters structure and execution and to evaluate their different duty modes of operation. Detailed description of the models of ac/dc, dc/ac, ac/ac and dc/dc virtual power converters and their auxiliary circuits are given. Learning possibilities and restrictions of the described software...
The electric power generation using hydro potential is increasing around the globe due to many reasons like increasing power demand, deregulated markets, and environmental concerns etc. At the same time, extended transmission networks, higher degrees of interconnection between different networks, and fast connection and disconnection of the heavy loads demand flexible, fast power generation and consumption...
The paper deals with the automatic generation of global model of static converters without the description of their environment. The considered models are average and exact models (i.e. with ideal switches). These models are obtained by using a software tool named AMG (for Average Model Generator) with a priori on the control mode and behaviour of the static converter. In this paper, an extension...
Dynamical phenomena like oscillations and instability in railway power systems have come into concern in the experts' community the recent years. In several occasions, modern advanced electrical rail vehicles have been a source for low-frequency power oscillations leading to an unstable power system due to lack of damping, and as a consequence operational problems. Traditionally the dynamical behaviour...
Simulation tools for learning power electronics are grounded aimed to study the circuit structure and execution and to evaluate the working possibilities in different duty modes of operation. The power converter estimation factors, features and characteristics are evaluated. Detailed explanation of the models of AC/DC, DC/AC, AC/AC AND DC/DC power converters and their control circuits is given. The...
The problem of electric drive design concerns the multi-criteria non-linear problems having a number of solutions. In daily practice the search of optimum solution bases a great deal on the designer intuition and experience. Therefore, multiple obtained results have a low degree of equipment use, unwarranted complexity, or excessive cost. Proposed approach is devoted to implementation of the novel...
Fuel cell with supercapacitors is a multi-physical system which, in association with converters, becomes hybrid. To model this complex system, different proposals have been made in literature. In this paper, Component Hybrid Dynamic Nets (CHDN) are used to model this system. CHDNs are a graphic model for hybrid systems, which allow each component of the hybrid system to be represented; moreover a...
