The world is now moving towards Electricity 4.0. Energy efficiency is an inherent component of Industry 4.0. A smart grid which monitors the inflow and outflow of energy data collected through strategically placed sensors is the first step in realizing Electricity 4.0.
Various parameters as mentioned below track the usage of energy, both from a quantity and quality perspective.
1. SAIFI (System Average Interruption Frequency Index)
SAIFI is measured in units of interruptions per customer. It is usually measured over the course of a year, and according to IEEE Standard 1366-1998 the median value for North American utilities is approximately 1.10 interruptions per customer.
2. SAIDI (System Average Interruption Duration Index)
SAIDI is measured in units of time, often minutes or hours. It is usually measured over the course of a year, and according to IEEE Standard 1366-1998 the median value for North American utilities is approximately 1.50 hours.
3. CAIFI (Customer Average Interruption Frequency Index)
CAIFI is designed to show trends in customers interrupted and helps to show the number of customers affected out of the whole customer base.
4. CAIDI (Customer Average Interruption Duration Index )
CAIDI gives the average outage duration that any given customer would experience. CAIDI can also be viewed as the average restoration time.
CAIDI is measured in units of time, often minutes or hours. It is usually measured over the course of a year, and according to IEEE Standard 1366-1998 the median value for North American utilities is approximately 1.36 hours.
5. MAIFI (Momentary Average Interruption Frequency Index)
MAIFI is useful for tracking momentary power outages, or “blinks,” that can be hidden or misrepresented by an overall outage duration index like SAIDI or SAIFI.
All these are reliability indicators used by electric power utilities.
The availability and reliability of electricity is crucial and an interruption or diminished quality would lead to serious consequences.
Power disturbances/blackouts or poor quality power impact critical power buildings on the level of business continuity, costs, safety or all of these.
The ultimate aim of Electricity 4.0 is to enhance maintenance and minimize disruptions. Tracking the indices listed above helps to monitor these important data points. Necessary alterations can be made as necessary once these data is available with the concerned authorities.
Power is the backbone of the industry. It is extremely important to make the foundations sturdy before we venture into implementing Industry 4.0 in other segments. A failure in a critical component in the manufacturing process results in enormous costs, so do issues with regards to electricity and power.
