The Challenge

AES station C is a 600MW combined cycle gas turbine power station located in County Antrim, Northern Ireland.Electricity is generated at medium voltage (15kV) and converted to 275/110kV by step up transformers to meet Northern Ireland’s Electricity (NIE) transmission system requirements. The medium voltage is also stepped down to provide the stations auxiliary power requirements.With the CCGT power station being one of the largest in NI, one of the main challenges was to assess the arc flash risk hazard across the entire site under a number of different switching and loading scenarios. To calculate the worst case potential Arc Flash hazard across the entire network, it was critical that a number of different switching scenarios were developed closely with AES to reflect onsite operational procedures.
Premium Power determined that it was advisable to introduce new protection settings at a number of locations, in order to improve the reliability of the electrical network, as well as providing safer working conditions in electrical switch rooms. Proposed protection settings were also provided in order to significantly reduce the severity of the potential arc flash hazard at a number of points along the network.

Premium Power conducted a detailed analysis of the power stations electrical network. A software model of the electrical network was developed using advanced modelling software. Arc flash analysis proved that there were a number of areas that required immediate action to mitigate against the high incident energy levels calculated at some locations.
