6 FAQs about [Maldives three-phase reactive power compensation capacitor]

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.

Can a capacitor bank be used as a compensator for inductive reactive power?

Therefore, the use of capacitor banks in any of their versions (single-phase, three-phase, scalable battery, SVC, etc.) is the most economical and sufficient solution. In this study, a calculation algorithm is proposed to obtain compensators for the inductive reactive power of the load, consisting only of single-phase capacitor banks.

What type of capacitor is used for reactive power compensation?

In the past, rotating synchronous condensers and fixed or mechanically switched inductors or capacitors have been used for reactive power compensation. Today, static Var generators employ thyristor-switched capacitors and thyristor-controlled reactors to provide reactive power compensation.

What is the difference between classical reactive power compensation and hybrid compensation?

In the first case, assuming that only capacitors exist in the compensation system, classical reactive power compensation was applied. In the second case, hybrid compensation was done by using hybrid reactive power system with synchronous motor, which is the subject and purpose of this study.

What are the different types of reactive power compensation?

Capacitors can be connected at different points in the network to improve the power factor of one or more loads, by which we differentiate three types of reactive power compensation: central, group, and individual.

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.
