6 FAQs about [Calculation formula for reactive power compensation capacity of energy storage power station]

How does a reactive power compensation system work?

With a reactive power compensation system with power capacitors directly connected to the low voltage network and close to the power consumer, transmission facilities can be relieved as the reactive power is no longer supplied from the network but provided by the capacitors (Figure 2).

How do you calculate reactive power?

Active power can be measured by inserting a wattmeter into the circuit. To calculate the reactive power, the formula for calculating the reactive power (Q) can be used: Reactive power (Q) = √ (S^2 – P^2), with: Q: Reactive power in volt-amperes-reactive (VAR). S: Apparent power in volt-amperes (VA). P: Active power in watts (W).

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.

What is a power compensation system?

They provide solutions to two types of compensation problems normally encountered in practical power systems: The first is load compensation, where the requirements usually are to reduce the reactive power demand of large and fluctuating industrial loads, and to balance the real power drawn from the supply lines.

How does reactive power compensation affect transmission losses and energy consumption?

Transmission losses and energy consumption are reduced and expensive expansions become unnecessary as the same equipment can be used to transmit more active power owing to reactive power compensation. A system with the installed active power P is to be compensated from a power factor cos φ1 to a power factor cos φ2.
