Application Case of FGI Static Var Generator (SVG) in a Cement Plant in Pakistan
1. Project context：
As a significant building materials production base in the local area, this cement factory has extremely high requirements for power quality and power supply stability. Due to the extensive use of large motors, crushers, fans and other equipment in the cement production process, there are serious reactive power surges, harmonic pollution and three-phase imbalance problems in the power grid, which seriously affect production efficiency and equipment lifespan.
2. Challenge：
(1). The low power factor of the power grid leads to electricity penalty charges.
(2). Frequent reactive power fluctuations affect the operation of sensitive equipment within the factory.
(3). Harmonic currents cause the transformers and cables to overheat.
(4). Unbalanced three-phase loads result in voltage fluctuations.
3. Solution：
As a professional and high-quality static var generator manufacturer, FGI provided the Gharibwal Cement Plant with the SVG-C7.5/6 type static var generator (SVG). This equipment has the ability for rapid dynamic reactive power compensation and can respond to load changes in real time, effectively enhancing the stability and power quality of the power grid.
4.Product superiority：
(1). Enhance grid stability: Real-time compensation of reactive power to maintain voltage stability.
(2). Increase transmission capacity: Release line capacity and enhance power supply capability.
(3). Eliminate reactive power surges: Suppress instantaneous reactive power surges caused by motor startups, etc.
(4). Filter out harmonics: Effectively suppress characteristic harmonics such as 5th and 7th.
(5). Balance three-phase system: Automatically adjust three-phase current to improve imbalance issues.
5.Implementation effect：
Since the implementation of FDSVG, the power factor of the cement plant has gradually stabilized, effectively avoiding the reactive power penalties imposed by the power company. The fluctuation of the grid voltage has been significantly reduced, the operation of key production equipment has become more stable, the harmonic content has dropped significantly, the temperature rise of the transformers has improved noticeably, and the overall power quality has been comprehensively enhanced.
6.Conclusion：
The FDSVG static reactive power generator of FGI has demonstrated outstanding performance and reliability in the demanding industrial environment of the Pakistani cement industry. It not only ensures production continuity and energy efficiency optimization, but also provides an efficient power quality management solution for similar industrial enterprises.
