Look closer our power system interconnection

hello everyone, this is my first contribute to this blogsite.I want to give some information for you to about power system in Indonesia.Maybe this little information give you more comprehension about power system interconnection in indonesia especially in jawa-bali.

PT PLN PERSERO Penyaluran dan pusat pengatur beban (P3B ) Jawa-Bali is our state –owned electrical company and their function is to manage the energy from power plants to distribution system. Their framework is in transmission and load dispatch. P3B jawa – Bali controls energy that flows to 500kV , 150 kV and 70 kV interconnection system.

PT PLN P3B Jawa-Bali covers Java , Madura , and Bali islands and topology of their interconnection can be seen in picture below.

Heat generator

Okay, so here it goes, another story of my life, but from the engineering and scientific point of view. (This is the first post about it).  Just a week ago, my lab mates showed me one of my lab’s creations which I cannot upload the photo (I don’t have any permission to upload photos, but u can check it in my facebook). This device is an experiment for power generator by using heat energy or we usually call it ‘thermal’.

This is how it works : You can see the device which look like a circular windmill. If you see it more closely, then you would find the tiny magnetic dices on the outer parts of the circular windmill’s periphery. And there are also some magnetic dices that are stacked below the windmill. These magnetic dices’ colour is gold, and the magnetic dices around the windmill periphery’s colour is black. The gold magnetic dices are stacked (statically) as well as possible so that if the windmill starts rolling, the black ones and the gold one will have a really tiny space between them, that normally will evoke the magnetic force between them.

Okay, but in this device, you should put the device in hot water. The hotter the water is, the better result you’ll get. But you just soak it until the height of the water reaches 3/4 of the gold dices’ height. The heat from the water then will make the gold dices lose their magnetic charateristic, weakening their magnetic force, meanwhle the black dices still have their magnetism, so then if you imagine how the magnetic lines would be, you’d find that all the magnetic forces between them, will make the windmill start rolling.

They plan for this device to be applied as the generator in the industries, so that the heat it needs will be taken from the heat that the industries produced. So that it’ll make such a cycle of the heat.

I don’t know if you already know about it or not, but that’s the only news about tech that I’ve got here. So hopefully it informs you something.

And I am not really a critical type of person, so please if you have any question about it or about anything related to the Japan’s technology, just ask me, let me do the favor for you. Because I really want to share everything I got here, but often I don’t know what to share..
