GAS TURBINE POWER STATION - ARC FLASH HAZARDS & RISK ASSESSMENT
This plant had a closed cycle gas turbine that could produce up to 535.5 MVA at 19000 volts. There were various levels of voltage handled throughout the plant including 19 kV, 6.6kV, 220kV, 20Kv and 400 Volts. There was also a significant DC network to provide backup to critical loads.
of Irelands oil demand is supplied by Cork.
of Ireland’s energy fueled by oil and natural gas
This plant had a corporate requirement to assess arc flash hazards. Compliance with technical company standards was required with respect to specific corporate methodology. The facility required electrical risk assessments to be produced to ensure work is carried out in a safe manner and electrical safety training was required for operative staff.
HOW WE HELPED
We delivered a comprehensive arc flash report detailing the incident energy levels at all the locations in the plant using SKM power tools software package. All of the electrical equipment at various voltage bands were assessed under a range of different switching scenarios for their short circuit withstand capability. Task and location specific risk assessments were produced to the highest standards. A full electrical safety training programme was rolled out among operators.
- Recommended protection changes enabled the reduction of high incident energy levels across the plant
- Procedural changes as a result of the arc flash assessment were implemented leading to a safer working environment
- Protection coordination was improved which enhanced electrical reliability across the site.
- Operators now have the necessary awareness of the risks when working on electrical equipment due to their electrical safety training.
This gas combined-cycle power plant provides power to 400,000 homes in Ireland. The plant directly employs approx 40 people and the company who own the facility operate in more than 120 countries. .
”"This plant is a good example of a facility tasked with carrying out an arc flash hazard assessment while keeping within specific corporate methodology. It's very satisfying as electrical safety specialists to see procedural changes as a result of arc flash assessment as well as improved electrical reliability"George MoklElectrical Engineer
