6 FAQs about [Capacitor on-site compensation installation method]

What is the most useful method of capacitor placement in a power system?

The most useful method of capacitor placement in the power system is the analytical method. This uses the calculus for capacitor placements to calculate the minimum losses and cost savings. This method supposes that the feeder hasn‟t any sub branches. Its cross-section is the same in all parts and has been distributed equally in the feeder .

What is the objective of capacitor placement in the electric network?

The objective of capacitor placement in the electric network is to minimize the losses and improve voltage profile. The load and capacitor model, objective function, constraints and power loss calculations are described in this section. The loads and capacitors are modeled as impedance. The impedance model of loads and capacitors are given by Eq.

How to deal with capacitor placement for reactive power compensation?

Conventionally, there are two strategies to deal with the problem of capacitor placement for reactive power compensation. Either a bank of capacitors is placed at each power system bus or simply placing a bank of capacitors at the mains to enhance the overall system power factor.

Can optimum capacitor placement improve a system's performance?

The notion of appropriate capacitor placement can only improve the system's performance. The combination of PLI and MLI was presented in this study as a novel approach for optimum capacitor placement. This has the potential to enhance the system's load capacity while simultaneously lowering power loss. The IEEE 15 bus system is used in the testing.

How to optimize capacitor sizes based on a candidate location?

The second method is to use the ETAP Optimal Power Flow (OPF) program to optimize the capacitor sizes based on the candidate locations selected by the engineer. This method requires per-selected locations, since OPF can optimize the capacitor sizes but not the locations.

How to determine the maximum reduction of a capacitor?

The most popular result of analytical methods is the (2/3) rule. According to this rule, in order to come up with the maximum reduction, a capacitor with (2/3) drag reactive power from the beginning of the feeder must be installed in a place where its distance is (2/3) feeder length in comparison to the beginning of the feeder.
