What is a Reactive Power and Reactive Power Compensation?
Reactive power's function is to help in regulating the overall voltage. It works to keep the voltage's power in its intended state so that the active power can perform some productive tasks—reactive powers are generally called the alternating current systems by product. Typically, motor loads, including the other types of loads, use the reactive power for directing the electrons flow into something helpful. Reactive power compensation generally helps in providing the complete supervision and management of the reactive power. It is intended to enhance the execution process and smoothly implement alternating current power-based systems. Voltages are generally regulated by anticipating and amending the exact need of the reactive power from the loads. It fulfills these needs via the shunt capacitor & reactor compensations, dynamic compensation, and scheduling the adequate generation voltage.
Reactive power compensation Methods
Various methods used in the relative power compensation are mentioned below -
As the name states, the tools here are connected in a series manner aligned to the transmission line. Thus, it holds the liberty of getting hitched at any point of the line.
Shunt-connected reactors consume the reactive power and provide the constriction of the line-over voltages. In contrast to this, the shunt-connected capacitors are used to maintain the overall voltage levels.
3.Static VAR Compensators
It is an electronic device whose work is to provide reactive power over the transmission networks. Here, the term static mainly refers to the fact that there are no moving parts under the SVC.
The static compensators use the synchronous voltage sources to activate the reactive powers. It is generated with the help of a VSC - voltage source converter.
The synchronous condenser's main task is to enhance the pf of the electrical system. Thus, it generally gets installed over the front-end part of the transmission line.
What is the use of Reactive Power Compensation?
The reactive power compensation struggles with assisting and backing up the voltage & load. Therefore it is used in supporting the two significant things mentioned below -
The reactive power compensation assists the load support. It works in a way that leads to improving the system power factor's overall value. Moreover, it also helps in enriching the regulation of the voltage and stabilizes the substantial power extracted via ac supply. It works the best by eradicating current harmonic components. These components are generally elicited by jagged & volumed nonlinear industrial freights.
Reactive power compensation is generally used in transmission systems. It helps in bringing forth complete stability to the ac system. It does so by intensifying the transmittable active power. It requires the support of voltage, which helps diminish the unnecessary fluctuations of voltages present in the transmission line at a specific terminal.
What is the need for Reactive Power and Reactive Power Compensation?
The Reactive power needs to be compensated for two main reasons stated below -
Compensating the Reactive power helps in the overall regulation of the system's power factor.
Reactive power compensation helps in strengthening the overall stability of voltage.
Reactive power generally undergoes the oscillation process between the capacitor and the ac source. The frequency to which it oscillates is equivalent to twice the rated value. It is somewhere between 50 Hz to 60 Hz. In such a scenario, the Reactive power compensation helps you resist the circulation between the load and source.
