Claim:
1. A load sharing arrangement to share power production among generators that are connectable to an electric power network, wherein the arrangement comprises a device, comprising: a first interface for a digital communication line; a second interface for a busbar breaker; a third interface to receive measurements from a analog communication line; a fourth interface to send signals to the analog communication line; a fifth interface to control the sending of the signals through the fourth interface; means for simulating load situation of generators connected to the digital communication line for load sharing with other generators connected to the analog communication line, and for simulating load situation of the other generators connected to the analog communication line for load sharing with the generators connected to the digital communication line; a first load sharing unit; a second load sharing unit; and at least one internal communication line between said load sharing units, which first load sharing unit is arranged to handle information from the second, third, fourth and fifth interfaces, and from the internal communication line, and further arranged to handle communication of the fourth interface by utilizing the fifth interface, and send information to the second load sharing unit through the internal communication line, the first load sharing unit comprising said means for simulating a virtual generator by calculating the load situations of generators, the second load sharing unit being arranged to form an identifier to the device and to handle communication through the first interface according to a protocol of digital communication line, and send/receive information through the internal communication line.
