Introduction to reactive power:
Reactive power does not contribute anything to energy. Due to reactive power the efficiency of the energy systems decreases. The reactive power is the opposition of the load elements. It is consumed or generated by all the elements present in the system. Reactance which contributes the reactive power can be of resistive or capacitive. The paper mainly aims at making the power factor to unity by using the available techniques. If the power factor is more than unity then more power will be consumed by the elements than the required amount which in turn causes power loss which is to be reduced.
Capacitor compensation implementation:
The capacitor compensation method is the efficient method for reducing the reactive power. To overcome the voltage drops and power losses we will use the series and shunt reactive compensation. In the industries all the load elements are inductive so we use capacitive compensation make the capacitor leading and load lagging. In the circuit the capacitor bank is connected parallel to the load and a pic 16f877 is placed to measure the phase difference of the current and voltage. If the capacitor bank is off then there will be a more phase difference between the voltage and current and when it is on their won’t be phase difference which reduces the reactive power.
Advantages of capacitor compensation:
This is the cheapest method for reducing the reactive power. This is the effective method for keeping no phase difference between the voltage and current. It reduces the power loss in the generation and transmission. By using this we can control the usage of power by the elements which reduce the more power consumption. Thus we can conclude that capacitor compensation method is more advantageous than the synchronous motor method.
