Rapidly changing loads in industrial plants lead to undesirable voltage fluctuations caused by a varying load current. For quick changes this is referred to as flicker. Grid operators set stringent limits to the permitted flicker level imposed by industrial plants to avoid disturbances in the network. Flicker in lighting – critical for human wellbeing, it affects efficiency and performance of components in industrial plants, too.
SVC Classic and SVC PLUS® compensate and stabilize load-induced voltage fluctuations within a very narrow tolerance band and ensure compliance with grid requirements. With SVC PLUS®, flicker reduction factors above 4.5 (even into the 7 range) can be achieved.
For loads with fast varying reactive and active power, a dynamic reactive power compensator – the industrial SVC Classic with a thyristor-controlled reactor (TCR) and integrated filter circuits will be the right solution. Especially when arc furnaces are involved, the highly dynamic industrial SVC PLUS® will deliver best results.
High voltage stability and reduced flicker enable an increase in production and better utilization of cables, transformers, and drives. Steel mills especially benefit from compliance with utility requirements, as a penalty shutdown by the utility is a realistic threat. Due to the typically remote locations in the mining industry, voltage stabilization is important for reliable and efficient production.
