What you practise
Course project, about 14 hours
A 33/11 kV substation on IEC 61850: two vendors, GOOSE interlocking, and a 104 link to the utility
Design the automation of a new 33/11 kV substation for an industrial park. It has sixteen IEDs from two vendors, GOOSE interlocking and a 104 link to the utility control centre. You deliver a logical-node register, a GOOSE data set in SCL, a cause and effect matrix, a station bus design, a 104 point list and a desk test record.

Common questions
Is the IEC 61850 Substation Automation course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate does the IEC 61850 Substation Automation course give?
An EDWartens Certificate of Completion, issued when you have finished every module and passed the final assessment at 60%, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Is this the same as an IEC 61850 certification?
No, and it is worth being clear about what that phrase means. IEC 61850 conformance certification, run through the UCA International Users Group and its accredited test laboratories, applies to devices, not to engineers. Vendors such as Hitachi Energy, Siemens and SEL run their own paid classes on their own tools. This course is preparation for that work and for the interview, and it is not equivalent to any of them.
Who made the video lessons in the IEC 61850 Substation Automation course?
Triangle MicroWorks, on their own YouTube channel, as free training they publish alongside their protocol test tools. EDWartens did not make the videos and Triangle MicroWorks is not affiliated with EDWartens. What EDWartens wrote is the study plan, the module order, the practice tasks and the assessments.
Do I need to install any software?
No. The videos demonstrate the publisher's own simulation and test tools, and you can follow the method without installing anything. If you want to run the labs yourself, those tools are downloaded from Triangle MicroWorks on their own terms, and the course does not require it.
What should I already know?
Protection and switchgear basics, what a SCADA system does, and enough networking to be comfortable with Ethernet, TCP/IP, multicast and a managed switch. If you are new to industrial protocols, take the industrial communication course first.
How long is it?
Seven content modules and a final, about four and a quarter hours of video and roughly seven hours in total with the practice tasks and practice questions. The videos are long-form training sessions, not short explainers, so plan one module a sitting.
Where does this lead?
Substation automation work with transmission and distribution EPCs, grid utilities and their contractors, and the OEMs and system integrators who commission SAS panels. The same skill set is in demand on substation projects worldwide, including the Gulf, where IEC 61850 and a 104 link to the control centre are the normal specification.
What topics does the IEC 61850 Substation Automation course cover, module by module?
The IEC 61850 Substation Automation course has 8 modules. It opens with "The IEC 61850 object model and SCL", goes through "Communications: MMS reporting, GOOSE and Sampled Values", "Testing a 61850 system: factory, site and in service", "Simulating and testing your SCD design" and "IEC 60870-5 in service: application layer, stack and security" and ends with "Final assessment". The full list with minutes is under "What you learn" on this page.
What can I do after the IEC 61850 Substation Automation course?
After the IEC 61850 Substation Automation course: Read any IEC 61850 object reference down to the data attribute and name the logical node behind it; Tell ICD, SSD, SCD and CID apart and say who produces each and when; Decide whether a signal belongs on MMS reporting, GOOSE or Sampled Values. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.
What software and hardware do I need for the IEC 61850 Substation Automation course, and does it cost anything?
For the IEC 61850 Substation Automation course, software: None required. A text editor to read SCL files. The IEC 61850 simulation and test tools demonstrated in the videos are the publisher's own and are optional. Hardware: none. An IED on the bench helps but nothing here needs one. The course itself is free.
Is the IEC 61850 Substation Automation course suitable for me, and what level is it?
IEC 61850 Substation Automation is rated advanced. Advanced. Assumes you already work with protection relays, switchgear and a SCADA system, and are comfortable with Ethernet and TCP/IP. This is not a first course in electrical engineering. It is written for electrical and power engineers, and takes about 7 hours at your own pace.
Which jobs use the skills from the IEC 61850 Substation Automation course?
Skills from the IEC 61850 Substation Automation course (for example: read any IEC 61850 object reference down to the data attribute and name the logical node behind it) are used in roles such as energy engineer, power systems engineer, solar or EV technician and site engineer, and in power systems engineer work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
