Recently we took an excursion to “Energie Burgenland AG”. There were a lot of quite interesting things for us to see like the Main Control Center for the entire province of Burgenland.
Here you can see various displays showing the power grid of the area. With software you can simulate all kinds of situations like power cuts and the like.
An official of the company gave us an update on the wind power situation in Burgenland, as to how much KWH the existing wind power parks of Burgenland currently produce. See also: Windpark Parndorf
At first we visited the power provider’s headquarters. The guides showed us their workstations and explained the technical systems.
We were informed about wind and hydro turbines and a lot of other means to produce electricity. See this post on wind turbines! We visited “Parndorf Windpark” last year.
Then we went to see the power transformer station or electrical substation. I found it very boring. My colleague Elvis asked a lot of technical questions, but nobody cared to listen. I didn’t understand a word.
What is Current?
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons, the most common charge carriers, are negatively charged. They flow from relatively negative points to relatively positive points.
Electric current can be either direct or alternating. Direct current (DC) flows in the same direction at all points in time, although the instantaneous magnitude of the current might vary. In an alternating current (AC), the flow of charge carriers reverses direction periodically. The number of complete AC cycles per second is the frequency, which is measured in hertz. An example of pure DC is the current produced by an electrochemical cell. The output of a power-supply rectifier, prior to filtering, is an example of pulsating DC. The output of common utility outlets is AC.
An electric current always produces a magnetic field. The stronger the current, the more intense the magnetic field. A pulsating DC, or an AC, characteristically produces an electromagnetic field. This is the principle by which wireless signal propagation occurs.
Energy from Biomass
The treatment of organic materials such as manure, energy crops or remains from food production help generating electricity, heat or gas for combustion. Fed into the local grids biogas provides power for homes or businesses. Biogas is an important renewable energy source. This viable alternative to fossil fuels brings enormous savings to communities and is completely carbon neutral.
