Under integration of renewable energy resources many still understand only proof procedures to connect new power plant to public grid. The existing management systems aim to observe electrical and thermal grid condition. In defined situations renewable power plants will be turned off. Another huge problem is the natural fluctuation of direct renewable energy converter such as photovoltaic and wind...
The main issue of this work is to analyze and to test how the characteristic curve of the induction machine can be adjusted by the power electronic devices, when these are integrated into rotor circuits. In order to technically analyze the characteristic performances of the induction machine by switching between cages, the simulator software's MATLAB and NETASIM have been used. The simulated current-...
Demands in the area of electrical energy generation and distribution, as a result of energy policies, are leading to far reaching changes in the structure of the energy supply, which is characterised, on the one hand, by the substitution of conventional power stations by renewable energy generation, a decision which has already been made, and, on the other hand, by the changeover from centralised...
Climatic changes, environmental issues and Unite resources are keywords in the current discussion about the future of the energy sector. Because of the liberalisation of the energy markets a stronger tendency to decentralisation and to the combined generation of heat and power has become evident, and thus the opportunities of utilising renewable sources will increase. It is the task of the "Demonstration...
The subject of this research is the automated start-up procedure of a PI state controlled high-powered electrical drive by using evolutionary algorithms. Compared to the conventional PI speed control, applying the method of deliberate pole placement to the state controller design succeeds in improving the transient response of setpoint and disturbance changes. To put the PI state controlled drive...
