The reactive power compensation capacity is generally configured according to 40% of the transformer capacity; or configured according to actual reactive power.

Generally, a compensation scheme with co-compensation priority and sub-compensation optimization is adopted, and a certain proportion of sub-compensation products are configured in the case of three-phase load or reactive power imbalance.

Capacitor installation distance should be ≥ 30mm

The smaller the capacitor step difference is, the finer the compensation is. The ideal solution is: how much to make up, but for the cost of cost, there are usually 10, 20 thousand capacitors.

The root cause of harmonic generation is due to nonlinear loads. When current flows through the load, it does not have a linear relationship with the applied voltage, and a non-sinusoidal current is formed, thereby generating harmonics.

The reasons for the need for reactive power compensation are as follows: 1. The increase of reactive power will lead to an increase in system current, increase system active damage, reduce transformer output voltage and load capacity.
