Please note that there is a quite new book (400+ pages) about IEC 61850 for electric power systems:
IEC 61850 Principles and Applications to Electric Power Systems
Editors: Peter Bishop, Nirmal-Kumar C. Nair
Click HERE for details.The basic approach of the IEC 61850 standard series is to some degree independent of electric power systems and applicable in most automation domains.
Example: Monitoring of a process measurement
The following sketch shows an excerpt of a series of presentations I conducted recently.
A instantaneous measurement (in IEC 61850 xxxx.instMag) can be read at any time by some computer (on the left). The value could come with a quality information saying: Value is ok; and a timestamp.
Instead of polling the value, you may want to receive the value every 10 seconds automatically without polling. Next you may want to receive the value when it changes by +/- 10 % compared to the last reported value. Or you may want to receive a report in case the quality of the value changes from good to bad ... and so on.
IEC 61850 information exchange services for monitoring process values offer many additional possibilities to receive spontaneously sent information. The information to be sent can represent measurements you find in building automation, heating systems, diesel generators, pressure systems, car manufactoriing, ...
Click HERE for papers co-written by Nirmal-Kumar C. Nair (co-author of the new book) and myself (Karlheinz Schwarz). You will be surprised what we published more than 10 years ago! (some papers may not easily be accessible! ... sorry for that).
Stay tuned to the blog to see more on this in the future.
