IEC 61850: THE SECRET LANGUAGE KEEPING OUR LIGHTS ON!

Maybe you have not yet heard what IEC 61850 is all about! If you have no glue what it is, read a very great article from one of the IEC 61850 champions: Dr. Alex Apostolov (Omicron).

Click HERE to follow the post on LinkedIn with a link to the article.

You should read that article ... it is worth to read.

Excerpt ... from cover page:

"It’s like flipping a switch and turning on a light. You don’t think twice about it. Behind that simple flick of a switch is a silent promise: a commitment embedded deep within the grid. It’s not just wires and relays. It’s trust, engineered layer by layer, by minds that understand that milliseconds matter. This promise is powered by a language that’s not English or Spanish, but a digital dialect. It’s called IEC 61850, a standard whispering in the background, in real-time harmony. It’s already transforming the grid by streamlining design, accelerating testing, and enabling real-time intelligence that’s dynamic, digitized and decentralized. But first, let’s decode what it is, and why milliseconds matter more than ever."

"Dr. Alex Apostolov shares (in a podcast) how milliseconds, not megawatts, are shaping the future of protection engineering."

Remember: Protection engineering is very crucial for our living!

Do you know the PAC World Magazine? You should!

The PAC World Magazine - "Protection, Automation & Control World" - is a great global forum for the corresponding community:

https://www.pacw.org/

There you will find great discussions and use-cases on IEC 61850 ... and hints you don't find in the standards! 

Another source of background information is buried in the IEC 61850 Tissue Database:

Enjoy!

How To Bring Plant Engineers To The Table When Cyber Issues Are Discussed?

In my career as electrical and IT engineer I have experienced that engineers are quite often not invited to discuss the measures and plans for critical infrastructure protection with IT personnel.

It is completely different compared to the world of electric power system protection - I mean the applications of protection relays. Protection engineers are (in my understanding) the most crucial engineers. They are very important for the reliable delivery of electric power. Protection engineers are likely to attend any meeting when it comes to the reliability of the power flows. Protection engineers know what to do ... software people may help to implement the "what" and the IT personnel may help to solve the communication issues ... but the crucial parts are dominated by protection engineers!

Mr. Vytautas Butrimas, a globally well known engineer involved in cyber security of control systems has briefly discussed the "Berlin wall" between IT personnel and plant engineers.  

Click HERE for the four page paper written by Mr. Butrimas.

Either of the groups involved believes that his or her group is the center of universe. There is little communication between the IT personnel and the engineers. 

There are so many semipermeable walls between, e.g., politicians, company lawyers, economists, IT experts, and plant engineers. There is usually no way that experts from any layer are allowed to talk to the experts from the other layers. In the end: Each layer feels independent of the other layers ... which leads to what we see these days ... and may be even more in the future. Have you heard of a discussion between a power protection engineer and a lawyer or even a medical doctor?

It would help medical doctors to understand the basics of electric power system reliability ... and so on. Because medical doctors (and all other people of a society) depend 100% on available power.

So in the end: (Electrical) Engineers should be honored by the society ... the problem may be that the engineers are not wearing white coats but wear safety boots, safety helmets, goggles,  protective gloves, ... a single doctor may harm a few people ... a protection engineer may harm millions of people during a blackout caused by a misconfiguration of protection equipment.

Power Outage In Frankfurt Area (Germany) - And People That Need A Breathing Ventilator

I just read that in the western part of the city Frankfurt (Main, Germany) the electric power was down for more than 10,000 customers. A current transformer (CT, for measuring the current) blow up ... and produced a lot of smoke. The power went off from 17:15 on Tuesday 2021-10-26. The restoration took some eight hours!

The Hessenschau (de) reported that nine (9!) people that depend on breathing ventilators had been hospitalized. This critical situation tells us, that the ventilators did likely not have battery backup power - either in the devices or external. The devices we use for my wife have both two internal batteries which give (rated!) power for 16 hours for each device.

This brings two questions up in my mind:

  1. Why is it not required by law that all breathing ventilators have battery power for at least 24 hours?
  2. Why don't we have to have external batteries and inverters that would give power for several days?

Instead of bringing patients with the ambulances to the hospital, it would be much easier (faster and cheaper) to bring an emergency power supply package (batterie plus inverter) to the patients! Or?

There seems to be a wide area of improving the quality of life.

By the way, why did the CT (current transformer) crash? Was it too old or not ... or? I hope that my friend Andrea Bonetti (one of the most experienced protection engineers on this planet) will comment on the importance of CTs!

Any comment?

Add on (2021-10-30): 

First: The utility has told that more than 100 workers are involved in fixing the problem ... the current fix is provisionary only! 100+ workers means: It must be a big problem that needs so many people to fix. 

Second: It was reported that in an elderly care home the nurses had to use their mobile phone's flash light to look for the elderly people ... no emergency light! Hmm ... strange. A few 12V batteries and some 12V LEDs would have done a good job! Cheap and useful ... lifesaving! ... if somebody would care for their maintenance. The management has obviously decided to purchase a hand lamp per floor ... 👍 something is better than nothing. Note: A battery leak (AA or AAA batteries) may damage a flash light that is not used often ... or only in case of emergency. Non leaking batteries are available: Lithium Batteries are the right choice for emergency devices. I have replaced the typical AA and AAA batteries with Lithium batteries for all flashlights and outdoor devices like thermometer ... they withstand cold weather and do not leak ... life time likely 10+ years ...
