To provide reactive VAr control in order to support the power supply system voltage and to filter the harmonic currents in accordance with Electricity Authority recommendations, which prescribe the permissible voltage fluctuations and harmonic distortions, reactive power (VAr) compensators are required.
The inductive and capacitive reactances are frequency dependent (hence are only present in AC systems), oppose each other and are at right angles to the pure (DC) resistance. The net reactance, which is usually inductive, opposes the flow of current, and the power required to overcome this reactance is called reactive power (Q).
Reactive power control is conducted by thyristor valve which regulates current of TCR reactors and compensates excess reactive power of the capacitors in harmonic filters.
Static VAR compensators Static VAR compensators (SVCs) contain shunt capacitors and reactors, which are controlled by thyristors. They provide solutions to two types of compensation problems normally encountered in practical power systems:
To be honest, transmission and distribution networks are full of problems. But that’s nothing new, and you already knew that. This technical article will shed some light on solving some pretty severe problems in transmission and distribution networks by using reactive power (VAr) compensators.
When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation. It’s as simple as that. This could involve greater transmission capacity, enhanced stability performance, and enhanced voltage profiles as well as improved power factor.
