Energy demand is anticipated to be double by 2030. CO2 emissions should be halved to avoid global warming acceleration. Both issues place a major challenge on the generating capacity of all utilities, and on us as electricity end users. Energy efficiency becomes more than a cost issue today. It becomes part of the journey to ensure energy availability and preserve the environment in the future. Many organizations put energy efficiency at the top of their agenda as part of a green initiative and sustainable development strategic plan. Increasing efficiency has significant impact on energy savings.
Power factor correction
and harmonic filtering
Most utilities charge for peak electrical demand on each month’s electrical bill. The demand charge is to allow the utilities to recoup part of their capital investment in the distribution network they operate. Each customer pays a demand charge for its peak operating load. Often inherent in the structure of these demand charges is an allowance for some inefficiency but most utilities will offer an incentive to their customers to keep electrical efficiency (measured by power factor) high. Power factor correction devices improve overall electrical efficiency upstream of their point of connection in the electrical network and can be used to minimize utility kVA demand charges.
Power electronic devices that have rapid and frequent load variations have become abundant today due to their many process control related and energy saving benefits. However, they also bring a few major drawbacks to electrical distribution systems such as harmonics and rapid change of reactive power requirements. Harmonics may disrupt normal operation of other devices and increase operating costs. Symptoms of problematic harmonic levels include overheating of transformers, motors and cables, thermal tripping of protective devices, logic faults of digital devices and drives.
Harmonics can cause vibrations and noise in electrical machines (motors, transformers, reactors). The life span of many devices can be reduced by elevated operating temperature. Plus, rapid reactive power changes demand timely reactive power (VAR) compensation. Lack of timely and adequate VAR compensation can lead to voltage fluctuations in the electrical distribution system, impacting equipment operation, as well as product quality.
ZDDQ Active Harmonic Filter (AHF) provides an effective means to mitigate harmonics, reduce process-related voltage fluctuations and improve equipment operating life and system capacity. It can be part of a power factor correction and harmonic filtering system.
