Ehsan Dadashnialehi Third folder Bad Effects of Inductance in Power Distribution Line and Alternative solutions In power lines we have many issues that should be considered in order to gain the most efficient method of production and consumption of energy. One of these issues which should be taken into account is Inductance and its effects in the power line. The term Inductance, refers to a two -terminal element in electric circuits, in which the voltage across is proportional to the rate of change in the current. The equation of voltage and inductance relation could be shown like this: = . v L didt (L: inductance, didt : rate of current change, v: voltage). According to this equation, whenever we have inductance in large scale power distribution lin es we will have the following problems: voltage drop in the line, lower efficiency and higher cable rating. From an engineer’s point of view, it is always desirable to know how much inductance we have in the line to be prepared for the above mentioned effects. This paper mainly focuses on bad effects of inductance in the power line and how we could overcome these problems. Most of the Power lines could be simply modeled as a resistance (the element, in which the voltage across is proportional to the current passing through) which is serried by an inductance , and the geometry of the line will implement how much inductance is in the line.
