- Välkommen Nicolás
Nicolás Carrasco började hos oss 1 april 2024 och kommer närmast från Enercon där han arbetade som Grid Integration Engineer med ansvar bland annat för uppfyllande av nätanslutningskrav för vindturbiner. Han har tidigare även arbetat som konsult inom kraftsystemanalys samt som driftoperatör inom elnätsdrift. Vi välkomnar honom till Protrol Engineering där han kommer att stärka … Continue reading Välkommen Nicolás - Kurs i spänningsstabilitet och spänningskollaps
Upptäck en spännande kurs om Spänningsstabilitet och spänningskollaps, som presenteras i samarbete med Chalmers och Högskolan Väst. Mellan den 3-5 juni kommer våra erfarna medarbetare Evert Agneholm och Lena Max, tillsammans med Daniel Karlsson och Massimo Bongiorno från Chalmers, att guida dig genom en djupdykning i kraftsystemets stabilitet i ljuset av den pågående energiomställningen. Kursen … Continue reading Kurs i spänningsstabilitet och spänningskollaps - Vi välkomnar Jonas
Vi välkomnar Jonas Olsson till vårt team! Jonas började hos oss den 1 december och kommer med lång erfarenhet från elkraftsbranschen; senast som projektledare och gruppchef på Ringhals, innan dess som konsult inom kraftsystemanalys. Välkommen till Protrol Engineering! - Välkommen Sara
Vi välkomnar Sara Bengtsson som börjar hos oss den 3 oktober. Sara är en erfaren kraftsystemanalytiker som bland annat har jobbat med överensstämmelsesimuleringar, nätstudier och anläggningsprovning, vilket hon också kommer fortsätta göra hos oss. Välkommen till Protrol Engineering! - Elkraftdagen 2022
Last Wednesday (30/3 – 2022), the student fair Elkraftdagen 2022 held place at Chalmers University, and Protrol Engineering participated as an exhibitor to show the future electric power engineers who we are and what we do. It was lots of fun talking to other players in the electric power industry and especially the curious students, … Continue reading Elkraftdagen 2022
Services
Power System Analysis
We offer static and dynamic power system studies on several topics, such as:
- Load flow and short-circuit calculations
- Contingency analysis
- PV and QV analysis
- Frequency stability
- Transient and voltage stability
- Modelling of power system and components
- Insulation coordination studies (lightning and switching studies)
- Series compensation
- Sub-synchronous resonance
- HVDC and FACTS dynamic performance studies
Power Plant Studies
Protrol performs studies for all types of power plants such as combined heat and power, hydro, wind turbines, nuclear and PV.
- Grid code compliance
- Transient stability and low-voltage ride through
- Protection studies
- Power quality and harmonics. Filter design.
- Motor start
- Modelling of power plants and power plant components.
Validation of power plant performance
Validation of the power plant performance primarily comprises testing of governor and excitation system response. Protrol has elaborated a state-of-the-art plant test equipment based on in-house developed hardware and software with validated performance from both laboratory testbench setups and on-site tests. The test method supports both open-loop and closed-loop verification of controllers and equipment.
- Frequency control.
- Voltage control.
- Island operation test (using hardware in the loop simulations)
- Validation of simulation models.
- Compliance testing in regards to RfG requirements
- Pre-qualification tests for ancillary services (FCR-N/D, FFR, FRR, etc)
