Such reactive power compensation devices are: The passive reactive power compensation includes the capacitor bank installation for reactive power injection. The active reactive power compensation consists of the use of flexible AC transmission system (FACTS) devices to change the reactive power and active power requirement.
Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material. Capacitor banks are used for various purposes, such as power factor correction, voltage regulation, harmonic filtering, and transient suppression. What is Power Factor?
When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation. It’s as simple as that. This could involve greater transmission capacity, enhanced stability performance, and enhanced voltage profiles as well as improved power factor.
Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.
The inductive and capacitive reactances are frequency dependent (hence are only present in AC systems), oppose each other and are at right angles to the pure (DC) resistance. The net reactance, which is usually inductive, opposes the flow of current, and the power required to overcome this reactance is called reactive power (Q).
The generated KVAR of the capacitor bank is given by… Reactive power, Qc = (Q1 − Q2) = [P × tan (∅1) − P × tan (∅2)] = P [tan (∅1) − tan (∅2)] As we get the required compensation value of reactive power provided by the capacitor bank then we can find out the capacitance of that bank. ‘Xc’ is the Impedance offered by the capacitor.
