Static capacitive compensation devices reduce the lagging reactive power component transmitted over the network. If network conditions alter, the required leading reactive power can be matched in steps by adding and taking out single power capacitors (automatic PFC) to compensate the lagging reactive power.
The use of, both, static as well as dynamic compensators together may give cost-effective reactive power compensation for predefined transient limits of voltage response. This paper presents the pricing of reactive power compensation under steady-state and dynamic conditions of a system with fixed capacitor (FC) and STATCOM.
Dynamic Reactive Power Compensation and .... The wind-diesel-based isolated hybrid power system requires dynamic reactive power compensation for the fast recovery of voltage under load and input changes.
The reactive power re-quired by the load is 100 kvar. By in-stalling a 67-kvar capacitor, the apparent power is reduced from 142 to 105 kvar, resulting in a 26% reduction in current. The power factor is improved to 0.95. 70 · (0.9) = 63 kW can be supplied and transferred via the existing network.
Capacitors are used to supply reactive energy to inductive loads. Reactive energy must be produced as closely as possible to the loads to prevent unnecessary flow of current in the network. This is known as power factor correction. [VAr] The reactive power of the capacitor is a function of its rated voltage and current.
The power factor correction or capacitance of the power capacitor forms a resonant circuit in conjunction with the feeding transformer. Experience shows that the selfresonant frequency of this circuit is typically between 250 and 500 Hz, i.e. in the region of the 5th and 7th harmonics. Overloading of capacitors
