Design of a Low Cost Microprocessor-aided Voltage Stabilizer by using SVS (Static Var System)

In power transmission line voltage fluctuation is a very common problem. When the voltage at the receiving end is either high or low but not equal to the expected value then it is called voltage fluctuation. Voltage fluctuation creates various types of problems at the receiving end side. For example if the voltage becomes too high it may damage the electrical machines and devices connected with the system or if the voltages goes down too low then the electrical machines and devices cannot run properly. To eliminate this voltage fluctuation problem we have to make arrangements so that voltage maintains a stable value. Voltage stabilizer can be used to handle the voltage fluctuation problem. This paper will discuss about the design of a low cost microprocessor-aided voltage stabilizer which can maintain the voltage at a prescribe value. Here, in this voltage stabilizer we can set the value of the voltage as per our requirement around which we need to maintain the system voltage.
