Reactive power compensation capacitor temperature is high

What is reactive power compensation?

Once the problems of reactive power generation, transmission and distribution have been exposed, we will proceed to describe the actions that the customers can adopt in order to avoid or minimize the corresponding penalization in the electricity bill. These actions are covered by the denomination ‘reactive power compensation’.

How does reactive power affect the capacity of a generator?

Therefore, taking into consideration the basic Equation 1, we can conclude that, for a certain apparent power S, the higher the reactive power (Q) to be generated (in order to the supplied to the customers), the lower the active power (P) that the generator can produce. In other words, the generation of Q limits the capacity of generating P.

Can synchronous compensators compensate reactive power?

Instead of using capacitor banks, there is a different alternative to compensate the reactive power that is based on the use of synchronous compensators. These are synchronous machines that, operating with null active power, can behave either as variable capacitors or coils, by simply changing their excitation current .

What is reactive power?

1. REACTIVE POWER COMPENSATION AND HARMONIC FILTERING The reactive power required for the creation of the magnetic field in motors, transformers, and conductor lines oscillates continuously between the current generators and the consumers.

How much inrush current should a capacitor bank have?

In accordance with IEC 60871-1, the inrush current should be limited to 100 times the rated current of the capacitor bank. When a capacitor bank is initially connected to a voltage source, the transient charging current will flow, attempting to equalize the system voltage and the capacitor voltage.

What is a capacitor inrush current limit?

They are connected in series with each capacitor stage and enable efficient protection of the capacitor units. In accordance with IEC 60871-1, the inrush current should be limited to 100 times the rated current of the capacitor bank.
