Customer ServiceCapacitor 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.
Although the lowest payback period was obtained with distributed compensation with capacitor banks (0.4 years), it is not recommended in the presence of harmonics because the effects of current harmonics significantly reduce the useful life of these elements.
Having said the types of compensation, in this article we are going to discuss mainly about Shunt compensation using Capacitor bank. Since most loads are inductive in nature they consume lagging reactive power, so the compensation required is usually shunt capacitor bank. Shunt capacitors are employed at substation level for the following reasons:
The basic formula for calculating the size of a series capacitor bank is: C = 1/ (2πfX) Where, C is the capacitance in farads (F) f is the frequency in hertz (Hz) X is the reactance in ohms (Ω)
The concentrated compensation of the capacitor bank at the PCC is proposed because of the lower investment cost and ease of installation. However, the advantages of distributed compensation with harmonic filters have not been evaluated.
Series capacitor banks are placed in series with loads, lowering circuit impedance and providing negative reactive power to balance positive reactive power from capacitive components, thereby stabilizing voltage regulation. Series capacitor banks have some advantages over shunt capacitor banks, such as:
