PHOEBUS—an autonomous supply system with renewable energy: six years of operational experience and advanced concepts

Autor: W.A. Brocke, C. Meurer, H.G. Groehn, H. Barthels, Bernd Emonts

Publikováno v: Solar Energy. 67:131-138

The PHOEBUS demonstration plant has been supplying the Central Library of Forschungszentrum Julich (FZJ) with solar-generated electric energy all year round and independent of the public grid since 1993. The central task was to test the required stor

The fluctuating offer of renewable energies and their, in most cases, not synchronous use make it necessary to develop processes of energy storage both for short-term, relatively small amounts of energy with great power fluctuations and for long-term

PLASMA FEEDBACK CONTROLS FOR THE MODIFIED TOKAMAK TEXTOR

Autor: W.A. Brocke

Feedback control loops for the tokamak TEXTOR (ref. 1) serve several purposes (ref. 2). The impending modification of the tokamak TEXTOR requires the renovation of the existing feedback devices. The conceptual outline of the future computerized feedb

MEASUREMENT AND DYNAMIC CONTROL OF PLASMA POSITION IN TEXTOR TOKAMAK

Autor: G. Waidmann, W.A. Brocke

A control system for TEXTOR tokamak has been designed using a detailed model including important eddy currents in machine components. Plasma displacements and current are controlled by 4 different coil currents. Realistic power supply models were pro

Elimination of ir-drop in electrochemical cells by the use of a current-interruption potentiostat

Autor: W.A. Brocke, Dieter Britz

Publikováno v: Aarhus University
Britz, D & Brocke, W A 1975, ' Elimination of ir-drop in electrochemical cells by the use of a current-interruption potentiostat ', Journal of Electroanalytical Chemistry, vol. 58, pp. 301-311 .

Summary An apparatus is described which makes use of periodic current interruption in order to measure the true electrode potential, which becomes the controlled quantity in a potentiostatic circuit. Provided that switching and sampling times and per
