Winter school at TR Kočín: professional excursion of 4.EE and 3.EM pupils

Excursion to the 420 kV Kočín substation

The most important part of the event was a detailed tour of the 420 kV Kočín substation, which plays a key role in the Czech energy infrastructure. Its main task is:

• power output from the Temelín Nuclear Power Plant,
• ensuring power supply to the plant in case of failure of its own resources,
• stable operation of the transmission system of the Czech Republic.

ČEPS employees prepared a full-day block of lectures and guided tours for the students.

The programme included:

• Indoor exposure: visit of the substation control room, performance simulator of the dispatcher's workplace, a sample classrooms equipped with virtual reality for training work on very high and extra high voltage equipment.

• Outdoor part : tour 420 kV substation, getting acquainted with busbar system and instrumentation, inspections transformers and chokes, demonstration replacement diesel-electric power supply a battery backup systems.

The event was very well received by the students. The excursion allowed them to combine theoretical knowledge with practice and to see the operation of the transmission system directly in the field. The expert commentary of ČEPS staff, modern teaching technologies and the opportunity to enter otherwise inaccessible operations made the whole visit an extremely valuable experience.

THE VIEW OF THE STUDENTS:

A look into the heart of the power grid: A visit to Kočín

On Friday, March 20, our 4.EE class participated in the „CEPS Winter School“ excursion at the Kočín substation, one of the most important nodes of the Czech transmission system. Our program started with a tour of the outdoor very high voltage substations, where we saw the massive equipment providing power output from the Temelín Nuclear Power Plant. The main point of the programme was a visit to the Technical Supervision Centre (TDC Střed). Right in the control room, we watched specialists monitoring the power grid in real time and supervising the balance between power generation and consumption to prevent possible outages. In addition, they showed us the Training and Education Centre equipped with an advanced simulator. We learned that this is where dispatchers must regularly undergo rigorous re-testing and practice emergency scenarios to maintain their professional license. The field trip offered us a unique perspective on the complexity and responsibility of maintaining our country's energy security.
