Bank & Resistive/Reactive Load Bank), By Application (Power Generation, Government/Military, Maritime/Shipyards, Oil, Gas, & Nuclear, Data Centers, Industrial & Other) and any other business Segment if applicable within scope of report]
It should also be noted that the active and reactive load
of nodes varies with time, which in turn causes certain fluctuations in the voltage level in the network.
Similarly, the local reactive load
curve at the PCC and the output reactive power of the VOF based controller for the duration of 24-hours are shown in Figs.
Figure 5 shows the performance of the ELC based on fuzzy logic controller system connected to a balanced reactive load
. At 0.62 sec, 7.5 kW balanced reactive load
of 0.8 PF is applied to the system.
Because non-linear loads are neither leading nor lagging shifts of the current waveform with respect to the voltage waveform, they cannot be mitigated by application of an opposite displacement reactive load
. Instead, passive or active harmonic filters may be added to the power network to mitigate sinusoidal waveform distortion and improve power factor.
If the inverter is fed from rectifier, the capacitor C0 is placed on its input and receives the reactive load
energy and decreases possible overvoltages.
If the power system's reactive load
is capacitive (leading), the SVC will use reactors (usually in the form of Thyristor- Controlled Reactors) to consume VARs from the system, lowering the system voltage.
The induction motor is the most wide spread contributor to the reactive load
in industrial electric power system, its power factor tends to increase with the increase of power rating the power factor, however, decreases with decreasing load condition, and it should be increased during high load for the induction motor it may be improved by connecting a capacitor directly across the motor terminal or alternatetirely by connecting a capacitor to the lines supply the motors.
At the PCC bus, the whole power system can be seen as a power source connected with an active load and a reactive load
as shown in Fig.14 (a).
The new EcoPower machine series (not to be confused with the EcoPower reactive load
reduction tool introduced by the company at the last Fakuma) was heralded in June last year when Wittmann Battenfeld outlined its plans to reinvigorate the machine range.
Another concern is that all the calculations made on the electrical side of the design, such as voltage drops and inrush currents, depend on both the resistive and reactive characteristics of the wire, as well as on the reactive load
of the models being supplied.
Its new "Reactive Load
" power capacitor comes in sizes from 7.5 to 75 kW for use with Battenfeld's hydraulic presses from 27.5 to 550 tons.
