01 — KNOWLEDGE MODULES

What I know

Five modules I have run in production. Each one is common on its own. Combined in one person, they are rare.

  • Power systems

    Module active

    Electrical power, schematics, metering, protection and grid connection. I understand what happens in the plant when something trips, and why.

  • PLC programming

    Module active

    IEC 61131-3 in TwinCAT and PLCnext, Modbus and fieldbuses. I read other people's programs, find the faults and build new functions in systems that are running.

  • Software

    Module active

    Python, SQL and web. Data collection, databases, optimisation and tools that make operations visible.

  • Hydropower

    Module active

    REGULATIONS » Water rights permits, discharge conditions and the Swedish re-examination of permits (NAP).

    OPERATIONS » How the plant is actually run, with control, alarms and troubleshooting.

  • Frequency reserves

    Module active

    REGULATIONS » Svenska kraftnät's terms for FCR and mFRR, and prequalification.

    OPERATIONS » The daily bidding and delivery.

02 — PATCH BAY

Where they meet

I am most useful in the connections between the areas. Point at a connection to follow the cable.

  • Power
  • PLC
  • Code
  • Reserves
  • Hydro
  • POWER + PLC

    I read the electrical schematic and the program at the same time. Troubleshooting does not stop at the line between electrician and programmer.

  • PLC + CODE

    Data that stays inside the control system is of no use. I carry it on to databases and tools.

  • CODE + FREQUENCY RESERVES

    Bidding and optimisation based on how the plant actually behaves.

  • HYDROPOWER + POWER

    I see how the permit conditions and the electrical system together set the limits for operation.

> READ FILE KARLSSON_J

I'm Johan Karlsson. I work across power engineering, automation and software, and I do my best work where they meet.

A single week can include a PLC program in a power plant, a bidding strategy for a battery and an alarm flow that has to work at three in the morning in January.

I prefer assignments where I get to understand the whole chain, from the sensor in the field to the decision made on the data. I like working closely with your own team.
