Description
The bus frequency control function has the objective to maintain/re-establish the bus frequency at the desired frequency for a certain busbar or a combination of busbars in case the busbar or island is disconnected from the public grid. The latter especially in case the electrical load of the busbar is changing.
For every island, only one machine can be the “master of frequency”. Frequency control could be done either by a separate controller which is enabled by the bus frequency function and receives it’s setpoint from this module, or directly by the generator control type circuit in the ABB Advant EMS and the machine running in droop mode. In the latter case the frequency is maintained sending raise/lower pulses to the governor. Enabling frequency control for a machine is interlocked as long as the machine is connected to the public grid or to another machine that is the master of frequency. As soon as the frequency exceeds a high or a low limit an audible alarm is created.
