PRINCIPLE
Modern electrical equipment requires a stable voltage supply with low levels of harmonic distortion. However, electrical installations often generate interference causing disturbance to electrical networks. This leads to various problems such as:
Overheating
Malfunctioning of control or remote monitoring systems
High currents in the different phases or neutral lines
Resonance problems
As a result it is necessary to have harmonic filters. These are basically composed of capacitors and inductors. The addition of a resistor allows:
Easier filter tuning at installation,
Widening of the pass band,
Greater tolerance of temperature changes in the components.
APPLICATIONS
HDVC conversion stations (LCC & VSC)
Transmission voltage regulation
Power quality and transfer increase
Reactive power control
Voltage stabilization(Wind farm)
Dynamic voltage support (Railway)
Arc furnances, rolling mills (Metal)
Winders and crushers (Mining Industries)
Compressors, pumps and drill
Electrical propulsion and diesel systems
FONCTIONS
1. SVC STATION
– The static VAR compensators (SVC’s) improves power system transmission, distribution performance and control reactive power.
– A harmonic filter is composed from 3 elements: Capacitors, Inductors and Resistors.
– Inductors and capacitors divert the harmonics currents into the resistor where they are dissipated in a safe way.
