Inductive components, such as motors and transformers, consume reactive power, while capacitive components, like capacitors, supply it. Reactive power (Q) emerges due to a phenomenon called power factor, which is the ratio between the active power (P) and the apparent power (S) in an AC circuit.
By using capacitors for compensation, the company can generate its own reactive power and thus reduce the load on the grid. Reactive power compensation offers a variety of benefits, including improving energy efficiency, reducing energy costs and increasing grid stability.
Without compensation, the energy supplier would have to provide this additional reactive power, which would lead to increased grid losses and lower efficiency. By using capacitors for compensation, the company can generate its own reactive power and thus reduce the load on the grid.
Reactive power (Q) emerges due to a phenomenon called power factor, which is the ratio between the active power (P) and the apparent power (S) in an AC circuit. The apparent power is the vector sum of active power and reactive power. The power factor is defined as the cosine of the phase angle (ϕ) between the voltage and the current waveforms.
For a power factor of 0.65 and real power (P) of 100 MW, the apparent power (S) is 1 53.846 MVA and reactive power (Q) is 116,913 MVAR (as we know that P=S×cosφ; Q=S×sinφ). As can be noted, the reactive power in the network is of a higher value than the real power!
To summarize: Active power is the actual, usable power, apparent power is the total power in the grid, and reactive power is the power that is not used to perform tasks but is necessary for the operation of inductive and capacitive loads. These concepts are important to understand and optimize the efficiency and stability of power grids.
