Requests for reactive power compensation, voltage stability, and harmonic filter mitigation have increased as a result of the integration of renewable energies many other technologies into the electrical system. Capacitor banks are abundantly utilized in substations for improving overall power quality.
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.
At the same time, the presence of shunt capacitor banks impose constraints on apparatus present in a substation [1,2]. Currently, no specific configuration of shunt capacitor bank is recommended, grounded and ungrounded shunt capacitor banks can exist on the same transmission system.
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.
F. Insulation level of the shunt capacitor bank neutral Since the shunt capacitor bank is ungrounded the neutral should be fully insulated. In this case and for a 230kV system the basic impulse insulation level (BIL) of the neutral should be of 950 kV.
