Power Quality and Harmonic issues are often overlooked – either for a lack of understanding or for a focus on the symptoms of the problems harmonics cause rather than the underlying source.

The growing use of sophisticated controls and equipment in industrial facilities, the continuity, reliability, and quality of electrical service has become extremely crucial to many power users. Electrical systems are subject to a wide variety of power quality problems which can interrupt production processes, affect sensitive equipment, and cause downtime and capacity losses. Momentary voltage fluctuations can disastrously impact production and even greater impact of extended outages. Voltage fluctuations can also impact the stability and reliability of utility transmission and distributions. Rapidly varying dynamic loads and intermittent renewable generation sources can all impact the grid this requires systems that will provide the rapid voltage and reactive support needed to maintain grid stability

MISI Consulting have the expertise to model a complete network for load flow analysis to evaluate the reactive power requirement, voltage profile and for harmonic flow analysis. For Harmonic analysis, system response for each frequency for which a harmonic source is present will be performed. Total Harmonic Distortion (THD) of the voltage and current in the system, and frequency scans will be generated to evaluate the harmonic condition at the plant. If the harmonic distortion is found to exceed the acceptable limit harmonic filters would be designed and the effectiveness is evaluated using the network model. Models of various types of VSD and filters are available.

MISI Consulting have also the experiences in designing/construction of Low, Medium and High Voltage Reactive Power Compensation/Harmonic Filters:

• De-tuned filter
• Single or multiple tuned filter
• Damped filter
• High efficiency “C “ type filter
• Series connected filter
• Active Harmonic Filter

MISI Consulting offer a complete services from survey, harmonics measurement and investigation/trouble shooting to designing of mitigation equipment/harmonic filters.

Our Holistic Approach

Properly mitigating power quality and harmonics requires a system-wide approach since just treating one aspect of a system often results in different problems arising elsewhere. This is why MISI Consulting work with owners, managers, and their engineer professionals to make sure the electrical system matches the electrical requirements of the loads in the most effective, efficient, and cost-effective way possible.
