Load and distributed generation characteristics have both changed to require increased VAR support throughout the power system. Substation capacitor banks are the most economical form of adding VARs to the system, yet because of harmonics, grounding, and operational concerns, there are many different types of capacitor banks.
In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
The primary objective of this capacitor bank is to enhance the power factor of a factory. Local regulatory standards dictate that the power factor for bulk supply connections must be maintained at 0.9 or higher.
In this arrangement, capacitors are strategically positioned to create a star connection, and two such double-star-connected capacitor configurations are subsequently connected in parallel. The configuration of this capacitor bank is visually depicted in Figure 2.
Plan and elevation of a typical 115-kV transmission capacitor bank point, as the switch has an integral manually operated grounding switch. The switch is used to energize and deenergize the associated bus section between the capacitor bank and the main switchyard.
The uniqueness of this scenario lies in the decision to install the capacitor bank at the 11 KV voltage level, even though the factory receives power from the grid at a higher voltage level of 132kV, with an approved connection capacity of 12 megawatts.
