The aim of the invention is to use a separate device between the analog and digital communications lines to convert the digital load sharing information from the digital communication line to the analog communication line and vice versa. The device does not generate power itself for the load sharing and therefore does not disturb the load sharing of the generators on the both sides of the device. The device can be seen as a gate between the digital communication line and the analog communication line. The device simulates load situation of the generator/s connected to the digital communication line for load sharing with other generator/s connected to the analog communication line, and similarly it simulates load situation of the other generator/s connected to the analog communication line for load sharing with the generator/s connected to the digital communication line.

Load sharing arrangement

The apparatus and method according to the invention comprise a controller () 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 () to form an internal pressure reference value to replace the set pressure reference value when forming the control signal.

Pressure control in the common rail system of a combustion engine

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.

The modelling arrangement of the configuration situation of the electric power transmission network according to the invention comprises a modelling element () designed to be installed in each generator of the electric power transmission network. The modelling element () 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.

Modelling a power production network for distributing the load

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.
