  • Page 61: Load Shedding

    TECHNICAL DOCUMENTATION Load Shedding Functioning The load shedding is the ability to disconnect less important consumers if the Power plant is overloaded even when the full capacity is engaged; this prevents a blackout. Any module – generally one – in the Power plant can take care of excessive demand. If the KW demand exceeds the Power plant capacity and/or the frequency has dropped below a threshold for a given time, the dedicated module activates outputs to shed non-essential loads.
  • Page 62 TECHNICAL DOCUMENTATION The charts show the trip alarm and trip outputs depending on the Generator load or frequency: The trip counter sums the times during which at least one consumer is shed. It is reset at the same time as the alarm: A56_PRIME_90020-E-EN...
