Primary Load Shedding
The following main functions are included in the primary load shedding system:
• continuously checking changes into the total electrical network configuration
• continuously checking the energy balance in ev ery electrical island configuration
• calculation of the dynamic priority load tables
• generation of the load shed command when needed
• supervision of the total ABB Advant EMS computer system
• generation of reports after load shedding
• informing and guiding of the operators
The load shedding system continuously checks whether changes in the island configuration have occurred. As
soon as a change occurs, for example tripping of a generator, the load shedding system starts checking all the
individual island configurations. For every island configuration, the energy balance has to be calculated. If the
load in this island configuration exceeds the available generated power, it is necessary to shed the surplus of
loads.
For every island configuration, whi ch is momentarily in a steady state condition, the load shedding system has
to monitor continuously the power available from the generators in that particular island configuration, since
losing a generator or losing part of the capacity of a generator migh t cause the need for load shedding.
As soon as load shedding is started due to a change in the electrical network configuration, not meaning that a
real shed command is generated, the system starts calculating the dynamic priority load shed tables. Input for
this calculation is the data in the island configuration and the priority load tables for the several busses. For
every bus on which there are sheddable loads, such a priority load table is assembled.
