case studies
Poland
Customer:
POSCO E&C
Introduction/challenge:
The EPC contractor was oblivious to the very strict local regulations and standards which had to be explained and then applied in the basic and detailed design of the E&I scope. Installation works were conducted at the same time as the design study.
Solutions:
We provided thorough consulting services on the Polish standards and regulations and worked in two locations – our design office on construction site thus ensuring close cooperation of electrical designers, the installation contractor and the customer.
Scope of design:
- specific calculations for connection to the public grid operator
- electrical design of MV power distribution system including measurement system, relays and protections settings, selection and design of MV inverters and harmonic analysis
- electrical design of the LV power distribution system including relays and protection settings, selectivity, and design of LV inverters
- design and detail engineering of the Emergency Diesel Generator unit
- comprehensive design of cable trays, power cable calculations, preparation of cable schedules
- design of the earthing system for the entire plant
- site supervision during installation works
- as-built documentation
Customer:
Termomechanica Ecologica
Introduction/challenge:
TME continued works and deliveries within the WtE plant as a replacement of the previous EPC Contractor who left the site. Our challenge was to deliver E&I&C studies for the overall plant within a very tight schedule. The studies were supposed to include existing solutions and their adaptation to the new process requirements from TME.
Solutions:
The works were carried out in office and on site simultaneously together with site surveys. Our engineers supported the on-site installation teams and took part in commissioning and start-up.
Scope of design:
- electrical design of MV power distribution system including measurement system, calculation of relay settings, selection and design of MV inverters, harmonic analysis
- electrical design of the LV power distribution system including in particular calculation of relay settings and selectivity
- design and parametrisation of LV inverters
- design and detail engineering of the Emergency Diesel Generator unit
- comprehensive design of cable trays, power cable calculations
- preparation of cable schedules
- design of the earthing system for the entire plant
- as-built documentation

Customer:
Babcock Willcox Volund
Introduction/challenge:
We were faced with a challenge related to the relatively big step-up transformer, around 45 MVA, and low short-circuit power in system – there was a voltage drop in the MV network when switching on the transformer.
Solutions:
We used the pre-magnetisation system and magnetised the transformer core with a diesel generator. Thanks to this solution, the switching on of the entire facility was unnoticeable for the overall power system.
Scope of design:
- complete electrical design of the entire plant and specific calculations for the connection to the public grid operator
- electrical design of the MV plant including
- step-up transformer
- MV/LV transformers
- MV cables
