Design consultancy
Assessing and optimising performance of your power plant design and systems, connections or protections can help optimise reliability and increase efficiency. Our power system studies facility means we can now offer modelling up to and including 132kV.
Reliability and efficiency have always been key watchwords in the energy industry and, as we transition towards a zero-carbon power system, they remain at the heart of our ethos. One of the ways we add value to our services is by investing in new technologies and innovations to ensure we are operating with the latest systems.
PowerFactory, the leading power system analysis software application for use in analysing generation, transmission, distribution and industrial systems, is no exception. Using PowerFactory gives us the ability to conduct complex load flow, fault level and protection studies, analyse all power generation components and study power system phenomena. Modelling transient simulations prior to transformer ordering ensures compliance to P28, giving clients peace of mind.
“Our capability to model as we design further strengthens our ability to create turnkey solutions for clients,” said Maciej Milewicz, Head of Design. “We have long prided ourselves on our ability to take a holistic view of our sites, designing practical and pragmatic solutions for clients. Bringing PowerFactory in-house will give clients even more confidence in our systems and energy generation projects.”
Using PowerFactory in-house means we can look at any issues early on, ensuring we incorporate any required mitigations into both the project and the cost plan. Harmonic simulations allow us to check sites are compliant with G5, and this can be done at an earlier stage in the project to ensure further requirements are built into the project as it develops.
Services we offer include:
- Load Flow Studies
- Feasibility of Initial Equipment Design
- Check for Voltage rises and falls in local power system remain within compliance limits
- Verification of system equipment design
- Fault Level Studies
- Feasibility of Initial Equipment Design
- New Equipment Specifications (transformer, circuit breakers, switchgear, cables etc)
- Evaluate existing equipment fault level capacity against calculated fault levels
- Calculated to European and British Standard IEC 60909
- Protection Studies
- Calculate protection settings for new and existing sites
- Transient Simulations
- Transformer Inrush studies, ensuring transformers are compliant to P28 prior to ordering
- AVR and Governor Modelling
- G99 compliance studies
- Harmonic Simulations, enabling us to check sites are compliant with G5.
