Career Growth: Career as Electrical Engineers 2022
In this modern world, who can deny the contribution and need for electrical engineers? As the world is advancing towards growth, the need for economical but quicker systems is increasing.
SCADA systems are crucial to speed up industrial processes, bring automation in place for quicker decision-making and more efficient performance, along with reducing errors in data processing. Usage of SCADA can hence reduce the total operational cost and enable more security. SCADA systems can be applied in all forms of renewable and non-renewable energy sources.
The need for such automated, efficient, cost-effective and reliable systems has been identified, and will continue to grow. More and more industries are adopting SCADA because of the numerous benefits it provides.
How Does the SCADA System Work?
SCADA system is a software which can perform multiple functions simultaneously. It mainly involves data collection, communication, presentation and monitoring or control.
In data collection or acquisition, the system collects information regarding various processes. Its sensors and components can inform the system about pressure, weight, and limit of reservoirs in cases of water power supplies, and eradicate chances of any mishaps from happening. These sensors are highly useful and can not only save time and money, but also help in crucial decision-making.
To create a communication flow of information running between the operator and the system, SCADA sends information from its wired network. It also takes aid from the internet to make operations smooth and fast in real-time. However, sensors cannot follow network protocols (which are required for information transferred through the net). That is why RTUs are used in such cases.
SCADA can present the information collected from various sensors and substations so that it is easy to interpret by humans. SCADA makes use of the HMI system to make all the data visible to the operator, which otherwise would be nearly impossible, considering the complexity of so much input. the information that SCADA received comes from small, large or medium substations. They can also detect issues in the system and raise an alarm.
While we know SCADA systems can work without any external help from humans, but in certain cases when the automated system either fails to act promptly, or due to any other reason, humans can control the system by manually operating the switches. With that said, SCADA can monitor and operate most devices without assistance.
Despite automation having been recognized in very large-scale industries, its utilization is yet to reach its full potential. There are many industries where SCADA can be implemented to automate manual processes, reduce cost of operation and streamline functioning. SCADA can perform redundant tasks with ease, and automatic back-ups to save information, which may otherwise be lost. this ensures reliable and quicker operations.
Why Do We Need PLC SCADA Systems?
● It increases reliability
● Redundant tasks are easily performed, with minimal time consumption
● Quick identification of errors, or issues, and hence, quicker rectification
● Information on possibility of future problems are identified
● Provides more safety
● Reduces need for manual assistance
● More accuracy and increased efficiency
