Information

The purpose of the 'black start' test is to ensure The Royal Melbourne Hospital city campus automatically changes-over to emergency power and maintains the essential hospital load on emergency generators, whilst the cogeneration operators start (both turbines) and switch the campus to 'island mode' (main grid isolation) powered by cogeneration. Note the cogeneration plant only covers buildings powered from substation A, B, D, & E. Substation C - WEHI / PMC / CSB / Anatomical Path are not covered

  • Sequence:

    * Citipower > disconnects incomer No1 & No2 - (UPS areas are unaffected)
    * Emergency generators > start & pick up the essential load
    * Cogeneration plant > start turbine No1 ring-main one closed on load > start turbine No2 ring-main two close on load > 'island mode' > synchronize with grid
    * Emergency generators > shutdown into standby mode
    * Cogeneration plant > steam pressure returns to 850Kpa
    * Engineering > reset any tripped plant / equipment
