Structure of physical model for research of traction parameters of electrical vehicle

This paper will present a laboratory model for research of traction parameters of electrical vehicle. Closely, this laboratory model is used for research of electrical drive. The detailed description of laboratory model and some recorded data will be presented.

User P-Q diagram as a tool in reactive power trade

Trading with reactive power will soon become a very important part of electric energy trade. However, while trading, voltage regulation in portable and distribution systems must not be neglected. In order to balance the technical and economic aspects it is necessary to be familiar with the electric power system, the source of electric energy most of all, meaning the synchronous generator and its possibilities. These possibilities are shown in the synchronous generator P-Q diagram. We nowadays use static P-Q diagrams, provided by generator producers, which in most cases refer only to generators. This article presents a dynamic user P-Q diagram containing changeable parameters and showing a real availability of a synchronous aggregate.

Industrial communication network with programmable logical controller as a nucleus of mechatronic laboratory

This paper presents with the role of the programmable logical controller (PLC) in the mechatronic laboratory for the research on the electric vehicles, especially electric vehicle drives. The general specification and recommendation on the PLC characteristics for this purpose are given. Also some application of the PLC and test results are presented.

Technology nucleus for research on optimized electric eco-vehicle

In this paper the basic demands on structure and equipment of technology nucleus are laid down. This technology nucleus is a part of mechatronic laboratory for eco-vehicles parameter research and identification or drive component and system optimization. On the example of the technology nucleus usage, in the case of drive system energy efficiency optimization, the research of improvement and optimization frames is presented. The paper points out that good structured technology nucleus enables research for all types of drive systems.
