Application of Capacitors on Electric Power Systems

The capacity of a capacitor is dependent on the size and spacing of the conducting metal plates and the type of dielectric medium between the plates. Dielectrics can be paper, film, mica, glass, and even air. The value of capacitance varies directly with the area of the metal plates and inversely with the thickness of the dielectric. Figure 1

There are 4 banks of about 17 MVAR each. Static capacitors cannot be used for dynamic VARs by themselves, but they can free up dynamic VARs from generators that are outputing maximum VARs already. In my situation, the capacitors are needed because there is more load (both real and reactive) in the area than generation.

How to place a capacitor in an industrial plant?

Place capacitors at loads which consume significant reactive power. For example, place capacitor in an industrial plant which have less than 85% power factor and bus voltage less than 95% nominal. Combination between rule of thumb (so called 2/3 rule) and running series of power flow simulations to fine-tune the capacitor size and location.

What is a potential difference in a capacitor?

In capacitor there are two conductors with equal and opposite charge say +q and –q. Thus q is called charge of capacitor and the potential difference is called potential of capacitor. Let A be the insulated conductor with a charge of +q units. In the absence of any other conductor near A charge on A is +q and its potential is V.

How should the capacitor be sized?

Since the system condition is dynamic: change with the season, time of the day, and other special condition, the capacitor should be sized according to power factor criteria and such that it would provide an acceptable voltage regulation during most, if not all, such conditions.

What are the different types of capacitors?

Capacitors are of many types depending upon its shape, like parallel plate, spherical and cylindrical capacitors etc. In capacitor there are two conductors with equal and opposite charge say +q and –q. Thus q is called charge of capacitor and the potential difference is called potential of capacitor.
