Improving power quality by overcoming harmonics and power factor issues
Harmonics and power factor issues can be a side effect of today’s energy-efficient devices, which means the drive for greater efficiency has created a need to control harmonics and overall improvement in power quality.
For FM providers at an industrial facility, it is likely they have equipment that contributes to harmonic and power factor issues, such as variable speed drives and heating equipment.
Harmonic and power factor issues can cause equipment to fail, utilities to hit you with penalties, your business to miss out on opportunities and operating costs to rise significantly.
During an Australian summer the risk of these problems only increases as rising temperatures add even more pressure to the quality of power being utilised by energy-efficient devices.
And the scope of harmonics and power factor issues impact not only the FM provider, but almost everyone associated with the facility, including architects, engineers, designers, property managers and suppliers.
To address the impact this has on power quality, a facility manager can explore possibilities to implement active filters with compact, flexible designs and the latest features that combat harmonics and power factor issues.
By implementing the latest active filters there is the potential to deliver increased uptime, a safer work place, prolonged equipment life, and greater operational efficiency.
Schneider Electric’s AccuSine line of active filters has served the power quality needs of companies in these areas for years, with the company recently launching the AccuSine+ range, which includes updated power electronic components, while delivering new functionalities, enhanced performance, and a smaller footprint.
AccuSine PCS+ is a flexible, cost-effective solution for stabilising electrical networks that provides harmonic mitigation, power factor correction and load balancing.
A complete harmonic filtering solution that meets global harmonic standards, AccuSine PCS+ can be operated as a displacement power factor correction and load-balancing device independent of, or in conjunction with, harmonic mitigation.
AccuSine PFV+, an active reactive current compensation system, provides high-speed dynamic, stepless power factor correction and load balancing of electrical networks with lagging or leading power factors.
Schneider Electric has published a white paper on the issue that presents a power quality management framework – based on continuous and iterative monitoring, analysis and corrective actions – that improves power quality performance.
The framework can be applied to standalone or integrated energy/power management programs and will result in reduced unexpected downtime, extended equipment lifetime, and improved operating conditions.
