Abstract:
A processing arrangement for the fault situation of a local electric power transmission grid comprises a generator-specific element arranged to monitor the fault situation of a data communication bus and the statuses of the switches of the electric power transmission network and to compare the status data concerning the same switch. In case of a fault situation the generators change into droop control only if there are no other possibilities to continue with the normal adjustment of the generator.
Abstract:
The modelling arrangement of the configuration situation of the electric power transmission network according to the invention comprises a modelling element (7) designed to be installed in each generator of the electric power transmission network. The modelling element (7) is arranged to measure the state of the said switches until an open switch is detected and to detect the corresponding generator on the basis of the closed switch and thus to model the power transmission network comprising the detected generators and the area of the power transmission network belonging to the same electric network via closed switches.
Abstract:
The apparatus and method according to the invention comprise a controller (7) to form a control signal, which controller is arranged to receive pressure data on the CR system, and into which controller pressure reference data is set. In addition, the apparatus also comprises a module (9) to form an internal pressure reference value to replace the set pressure reference value when forming the control signal.

Abstract:
The apparatus according to the invention comprises a controller for forming a speed signal arranged to receive speed measurement data of the internal combustion engine as well as speed reference data. The apparatus additionally comprises a module for forming the internal speed reference value instead of the speed reference value set to be used when forming the control signal.
