Design of a Web-Interface and Novel Control Technology for Remote Hardware Experiment on Separately Excited DC Motor and Generator

Jagadeesh Chandra A P and Sudhaker Samuel R D

Laboratory based courses play a critical role in technical education. Stand-alone approaches in remote learning have grown tremendously in the past several years. One of the important components of remote learning in technical environment is the virtual laboratory tool integrated to perform real hardware tasks in near real time. This paper presents a web interface and a novel control technology for remote experimentation using new generation Internet based instrumentation tools. Virtual Instrumentation (VI) tools and Internet technologies have been used for developing graphics oriented client-end applications linked to practical laboratory hardware. It describes the ongoing research in this area exploiting current telematics techniques, which supports remote experimentation with real hardware via the Internet.

Distributed Control System for a Cogenerative Power Plant

Florin Hartescu and Ion Miciu

The paper presents a distributed control system for the realization of cogenerative supply of electricity and heat and, in given case, for their combination with waste heat recovery, particularly in combined (gas-steam) cycle industrial power plants. Modern electric power plants are large complex systems with many processes whose operations need to be optimized. The electrical networks are designed for transmission, repartition and distribution of electrical energy, so that they present various structures.

An optimization problem is usually a mathematical model, where we wish to minimize a numerical value that represents something like costs, energy losses, risks, errors etc or maximize something like profit, quality, efficiency.

The implementation of these functions is usually and objectively based on a trusted model that uses a trusted architecture, which is the platform of the security architectures.

Hydraulic Plant Remote Laboratory

Vladimír Žilka, Pavol Bisták and Peter Kurčík

In our work we present use of remotely controllable hydraulic plant for use in remote virtual laboratories.

Our setup is based on client-server architecture , while we use 2 different approaches and compare advantages and disadvantages of each of them.

First approach is based on Java Server application , in which the control algorithm is implemented on server side. Second algorithm uses PC-independend network card which runs its own TCP server and the control algorith is implemented on client side.
