How can we learn when our grid is upset just by analyzing SCADA data?

 

SCADA is a very useful tool for measuring real-time data pertaining to large industrial systems like the electric grid. Furthermore, since this data constantly monitors highway system is operating, we can see how our system is acting and if it needs help, all from the safety of our computer terminals. So when something like the grid is having a fault, it can be easily detected. This is How Scada Data Can Inform Us When the Grid Has a Fault.

“What makes 5G 5G and what are the benefits and drawbacks?”

5G is poised to disrupt the world of mobile communications. This is being driven by its greater radio frequency spectrum. 4G devices can receive signals ranging from 3 kHz to 6 GHz, while 5G can go up to 300 GHz! Although these Millimeter Waves allow for more connections, they also lack the ability to penetrate hard surfaces such as trees and buildings. This makes it one of the biggest barriers to mass 5G deployment, and will need to be solved by further research and innovation.

“What exactly is 5G and why is it so important?”

A revolution in the mobile world is coming. As traditional 4G networks are nearing their limit, the next generation of mobile internet connectivity, 5G, is just starting to spread. By using new millimeter wave technology, 5G networks have an order of magnitude faster connection, reaching speeds as high as a gigabyte a second! These fast speeds will catalyze the development of the internet of things, autonomous vehicles, and a host of other applications not yet thought up yet.

“How do fallen communication systems exacerbate power outages?”

When a power outage occurs, interdependent infrastructure systems will fail. When the phones and internet that makes up the communication infrastructure also fails, then it will make it more difficult for utility workers to bring power online. This is How Downed Communication Systems Could Delay Power Restoration.

Digitization and Its Implications for Manufacturing

“What is digitization and how will it affect manufacturing?”

With the rise of the industrial internet of things, engineering processes are moving more and more towards the digital realm. This means that components once limited to the physical realm, such as mail and design models, are moving into the virtual one as e-mail and CAD. This digitization will have a lot of ramifications for the manufacturing sector, where processes will now be less prone to human error and move a lot faster while being more prone to cyber-security issues. This are the Implications for Manufacturing from Digitization.

“How can we ensure that the bits in a CAN bus are all synchronous?”

CAN buses are a vital part of control infrastructure. Whether it be in the vehicles we drive or the drones that fly around us, CAN buses are there to make sure things work well. However, their synchronization needs to be ensured during operation. This can be achieved through the use of Bit Stuffing, in which any part of the data which has 5 bits of the same polarity 5 times in a row will have a bit of opposite polarity inserted after it. The bits can be unstuffed by the receiver once it takes it in.

“How can we improve energy security with blockchain?”

With the advent of the renewable energy revolution, energy is becoming more and more distributed and intermittent. As such, many consumers, utilities, and companies are pushing for energy systems to become more autonomously operated to better integrate these resources. However, the difficulty to keep track of all energy coming in and out could open up a number of security backdoors, allowing for malicious hackers to penetrate critical infrastructure. To combat this, blockchain technology can be implemented by tagging and keeping track of where energy comes from and goes to. This is How Blockchain Can Improve Energy Security.
