6 FAQs about [Compensation capacitor modified battery]

What is a capacitive compensation battery?

The capacitive compensation battery is obviously connected on the low voltage (LV) side during an opencircuit test of the transformer rated at 110 or 220 kV. For this purpose, the battery should be capable of a voltage of 6–22 kV equal to the voltage of the transformer primary winding.

What is the relative power of a capacitive compensation battery?

The relative power of the capacitive compensation battery in the SC tests, conversely, is higher with a higher transformer power. The relative power of the capacitive compensation battery is 0.66% for the 125MVA transformer and already 0.79% for the 625MVA transformer.

How many capacitors are in a hybrid reactive power compensation system?

The circuit diagram of compensation capacitors and peripheral hardware in the implemented hybrid reactive power compensation system is also given in Fig. 7. As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure.

How does a capacitor switched compensation system work?

The controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.

How to compensate for reactive current caused by EMI capacitor?

There is a novel method to actively compensate for the reactive current caused by the EMI capacitor. Moreover, the PFC current-loop reference is reshaped at the AC zero-crossing to accommodate for the fact that any reverse current will be blocked by the diode bridge. Both PF and THD are improved as a result. Figure 3.
