Earlier in the year I mentioned that I would embark on a year long project to understand the inner workings on an outdoor electric substation. So here I start after taking some time off to study my Chinese - which in fact has improved.

Now this project will basicaly entail creating a model of each unit that is in a subsytation, link them using wires and perhaps use 240V to simulate the working

Recent developments in High Voltage transmission and distribution systems have shown a gradual increase in DC transmission systems at very high voltage levels. High Voltage Direct Current (H.V D.C) has become common in developed countries due to reduced costs at high voltages as compared to Alternating Current (A.C) transmission. It is because of such reasons that the recently completed
