Why a Solar Plant Needs Active Compensation A Static Var Generator (SVG) is an active, IGBT-based power-electronics compensator that stabilises voltage, supplies or absorbs reactive power and filters harmonic current at the point of common coupling (PCC) of a solar plant. It turns unstable PV output into grid-compliant power for EPC contractors, electrical engineers, procurement teams and power-qu...
Even-order harmonics are current and voltage components at even multiples of the fundamental frequency — the 2nd, 4th, 6th and higher orders — that appear as asymmetric distortion in a three-phase power system. They behave differently from the familiar 3rd, 5th and 7th odd harmonics: balanced six-pulse rectifiers do not generate them, but asymmetry does. Half-controlled bridges, DC-off...
Harmonics are extra currents and voltages at integer multiples of the supply frequency that non-linear loads draw on top of the fundamental sine wave. Their effect is costly: transformers, motors and neutral conductors overheat, relays mis-trip, and equipment life shortens even below rated load. This guide covers measurement at the point of common coupling (PCC) and how to compare the main mitigat...
