Solar Power Monitoring

by Team Digireach

The biggest achievement, and also one of the best features of IoT (Internet of Things) is the ability to monitor devices remotely and take necessary action as needed. This monitoring feature has widespread applications, not the least of which being more efficient generation of energy from inexhaustible sources. And what better energy source than the Sun itself.

At present, the solar photovoltaic (PV) energy is one of the pivotal renewable energy sources. Solar energy is becoming a potential solution towards sustainable energy supply in future. As more and more Rooftop Solar PV Systems are getting integrated in the existing grids, there is even more need to monitor real time data from solar PV plants to optimize the overall performance.

Solar power plants require continuous maintenance and are hence limited in scale. However with IoT technology, we can remotely monitor the functioning of the solar power plant.

A monitoring system is an essential part of a PV plant. It allows the yield to be monitored and compared with theoretical calculations, and raise warnings in case of performance shortfall. This helps to rectify and detect faults before any appreciable production loss occurs. This same fault could take months before it is noticed and rectified in absence of a proper monitoring system, which would lead to unnecessary revenue loss.

In general, monitoring systems have to fetch, analyze, transmit, manage and feedback the remote information, by making the best use of the most advanced communication technology available. It also merges comprehensive use of instrumentation, electronic technology and computer software and has a huge potential in the upcoming years.

Why IIoT?

by Team Digireach

IoT (Internet of Things) is the future. The Industrial Internet of Things (IIoT) is a subset of the Internet of Things (IoT). It is basically collecting data/ information from the field through sensors relying it to the cloud using an IoT gateway. The data is then stored in the cloud storages and analysed and used as per the requirement of the user.

A lot of industry sectors come under the gambit of IIoT. Energy, electricity, manufacturing, logistics etc. are in the nascent stage of deploying IIoT to garner the benefits. Financial benefits of fine-tuning the services by deploying IIoT can run into billions of dollars.

The advantages of IIoT:

  • Better Connectivity: The production personnel will always be aware of the flow of manufacturing at their plant. Individual efficiency of an equipment or a personnel can be tracked.
  • Better deployment: The bottlenecks and efficiency in a plant equipment can be readily read from the data collected. Efficient deployment of the resources can lead to increase to better productivity and less wastage of time.
  • Zero idle time: A constant track of resources and their usage. In a large factory it happens a lot of time that the resources remain idle which effectively is down-time for the production process.
  • Accuracy/ Quality: Automated tracking of the production process and removing manual intervention can lead to better quality of end-products.
  • Safety and repair: Limited manual intervention leads to better safety standards. Preventive detection of failure patterns can lead to timely intervention and service of the equipment. This leads to reduced downtime.
  • Logistics: The Industrial IoT (IIoT) can provide access to real-time supply chain information by deploying sensors at the different vital points in the value chain. A lot of the manufacturing plants have an ERP (Enterprise Resource Planning) at their manufacturing plant. Effective reporting enables manufacturers to collect and feed delivery information into ERP. By connecting plants to suppliers, all the parties concerned with the supply chain can trace inter-dependencies, material flow and manufacturing cycle times. This data will help potentially reduces capital requirements, manufacturers predict issues, reduces inventory and
  • Cost savings: All the points mentioned above ultimately lead to reduction in the cost of manufacturing.

Another industry term which is interchangeably used with IIoT is Industry 4.0. Industry 4.0 is the current stage of the industrial revolution. It represents the use of Industrial Internet of Things (IIoT), in manufacturing. Industry 4.0 focuses on the use of the cloud, gateways and communication networks to monitor factory processes and make data-based decisions.

Electricity Reliability Indices

by Team Digireach

We are entering an energy intensive world. It is very important to keep track of the energy utilized by the consumers so that necessary action can be taken to optimize it’s usage. There are various reliability indices which help us in determining the efficiency of distribution system.

SAIFI
SAIFI is the average number of sustained interruptions per consumer during the year. It is the ratio of the annual number of interruptions to the number of consumers.

SAIFI = (Total number of sustained interruptions in a year) / (Total number of consumers)

SAIDI
SAIDI is the average duration of interruptions per consumers during the year. It is the ratio of the annual duration of interruptions (sustained) to the number of consumers. If duration is specified in minutes, SAIDI is given as consumer minutes.

SAIDI = Total duration of sustained interruptions in a year / total number of consumers

CAIFI
CAIFI is the average number of interruptions for consumers who experience interruptions during the year. It is the ratio of the annual number of interruptions to the number of consumers affected by interruptions during the year. Consumer is counted only once regardless of the number of interruptions.

CAIFI = Total number of sustained interruptions in a year/Total number of consumers affected.

CAIDI
CAIDI is the average duration of an interruption, calculated based on the total number of sustained interruptions in a year. It is the ratio of the total duration of interruptions to the total number of interruptions during the year.

CAIDI = Total duration of sustained interruptions in a year/total number of interruptions.

MAIFI
MAIFI is the average number of momentary (less than 5 minutes) interruptions per consumer during the year. It is the ratio of the annual number of momentary interruptions to the number of consumers.

MAIFI = (Total number of momentary interruptions in a year ) / (Total number of consumers)

The above indices are the commonly used parameters used to judge the reliability for electricity generation, transmission and distribution. These outage indices are based on the duration of each power supply interruption & the frequency of interruption. It is clear that all three major functional components of the power system – generation, transmission & distribution contribute to reliability.

IoT and monitoring of electrical parameters enables to keep track of the various energy parameters which can be used to further judge the reliability of electricity distribution. The tariff can be adjusted according to this reliability indices. It would be a win-win situation for the all the stakeholders in electricity domain. Also, the end consumers will be benefited and charged according to the quality of power delivered. It would be a step towards Electricity 4.0.

Manufacturing safety

The Internet of Things is the superhero of this era. There is a lot of fancy tech that it can accomplish in microseconds. But its most remarkable super power is the ability to rescue human beings from danger just like a superhero. It can make people feel protected.

IoT is a superhero that uses its powers (Internet connection) in ways that boggles the mind and defies the concept of impossibility.

Factories and manufacturing plants can be some of the most dangerous places to work at because of hazardous elements like thermal extremes, highly concentrated toxic or flammable substances and low oxygen levels that are generally controlled by manual or sensory procedures. There are some processes require employees to handle lifting and moving equipment . Any mishap or tampering in even one of these can cause severe harm and even loss of life.

What are the current problems with providing workers with enough protection?

Factories must be able to provide effective protection while not burdening the worker so much that they are impeded in carrying out their tasks in an efficient and effective manner.

How can workers actually be protected?

This can be done by removing the uncertainty factor from the equation. The Internet of Things enables real time monitoring to detect any potential and currently occurring hazards. There are different kinds of sensors that have a specific function. While we had sensors earlier, now we have smart sensors which can either send alerts or take action according to the stimulus received.

The smart objects can be wearable or fixed depending on its functions. Activity-aware smart objects record the activity around it while policy-aware smart objects interpret the activity in a particular context. Process-aware smart objects guide workers with solutions based on lightning quick analysis of the data received from activity and policy smart objects.

Monitoring is done on three levels, namely: environment, situation context and the humans themselves.

The wearables mentioned earlier can measure an employee’s heart rate and other body vitals to keep track of their health. Many accidents can be prevented by this kind of regular check up. Employers can be alerted if an employee is too fatigued. Since optimum performance can only come with good health, employers can make sure to give appropriate rest breaks.

Parting thoughts:

The storm of Internet enabled devices is upending old, obsolete techniques and making way for the new. Your friendly, workplace IoT is here to stay and save the day.
