A: In theory, the best way to achieve resilience is where the demand is reactive, where it is compensated, and the entire system will have no reactive current activity. But it is impossible to do this in practice. Since both the transformer and the transmission line are still various loads, reactive power is required. Therefore, in the practice of the power grid, there are several compensation methods for the equipment orientation of the equipment: 1 substation collection compensation; 2 distribution line dispersion compensation; 3 load side gathering compensation; 4 user load local compensation.
Regarding the reactive power compensation of the low-voltage distribution network, the load side gathering compensation method is generally adopted, that is, the automatic power factor adjustment device is used in the low-voltage system (such as the low-voltage side of the transformer), and some or all of the capacitors are automatically input or cut off following the change of the load. capacity.
