6 FAQs about [Automatic compensation capacity of complete capacitors]

What is a compensation capacitor?

The compensation capacitor reduces the total impedance of the series circuitry consisting of the Helmholtz coils HHS 5210-100 and the NFCN 9732-120 at the operating frequencies of 50 to 60 Hz. It allows continuous currents of up to 8 A rms at generator voltages of less than 70 Vrms...80 Vrms.

How many capacitors are in a compensation unit?

Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example, 300 kvar consists of six power capacitors, of 50 kvar each. Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps.

What is a compact capacitive compensation scheme?

In this article, a compact capacitive compensation scheme using a minimal number of compensation capacitors is proposed to realize series/series–parallel (S/SP) compensation for adjustable CV output and series/parallel–series (S/PS) compensation for adjustable CC output, achieving reduced system weight, volume, and cost.

How a capacitor compensation circuit is controlled?

Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.

How many capacitors are in a compensation bank?

Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ‘fine-stepping’ mode.

What are automatic reactive power compensation systems?

The automatic reactive-power compensation systems used for load-related control of the reactive power comprise a PF controller and a power section. Power capacitors without reactors (for linear loads) or with reactors (for non-linear loads) with parallel discharge resistors, Fuses for the capacitor branch circuits.
