Why Reactive Power Is Needed. Why Do We Need Reactive Power. Reactive power is either generated or absorbed by electric generators or in some cases devices known as capacitors to maintain a constant voltage level commonly referred to as providing voltage support Generators providing voltage support often suffer heating losses that result in a reduced ability to generate real power. Additionally some appliances such as electric motors need negative reactive power to run their magnets properly. Reactive power can be leading or laggingWhile it is the active power that contributes to the energy consumed or transmitted reactive power does not contribute to the energy.
Reactive power VARS is required to maintain the voltage to deliver active power watts through transmission lines. This are acceptable at some level. Why Do We Need Reactive Power. Reactive powerthe delay between voltage and current at a given pointis subjected to transmission constraints. Transformers and transmission lines introduce inductance as well as resistance I. Active power is a separate quantity and reactive power is a separate quantity.
1 Reactive power control mode.
Reactive power is essential to move active power through the transmission and distribution system to the customer Reactive power is required to maintain the voltage to deliver active power watts through transmission lines. Motor loads and other loads require reactive power to convert the flow of electrons into useful work. Reactive power is essential to move active power through the transmission and distribution system to the customer Reactive power is required to maintain the voltage to deliver active power watts through transmission lines. Reactive power is regulating the voltage by three ways either tap changer of transformers but this is marginally 2nd provide reactive compansators like synchronus kvar generators third it naturally some times by distributed capacitance of line if not heavely loaded due to ferrenti effect but this is some tines. As a result it is often necessary to produce reactive power close to the location where it is needed. Reactive power is an inherent part of the total power.
