The problem of co-voltage control and reactive load conductivity in a large stand-alone power system object, such as a transport vessel that contains synchronous generators and installation of reactive power compensation. Existing technical solutions in stationary power systems provide compensation for the mean value of reactive power, wherein the transients are ignored. However, the work of autonomous power plant is characterized mainly by a change of regime with frequent drive start. Commensurable capacity generators and electrical load results in significant dynamic voltage deviations during load switching, which is proposed to use as one of the signals to form the capacitance of capacitors connected. Search control laws reactive current in the power plant, containing generators and capacitors, should be carried out taking into account the mutual influence and interaction.

With dynamic reactive power compensation proposed voltage sag and inductive conductivity to calculate the load for one period of the network and used to generate a control signal installation of reactive power compensation. An analysis of the dynamic properties of the control system of autonomous electric power plants with reactive power compensation has shown that the proposed joint management significantly affects the accuracy and dynamic performance of the system voltage regulation. The voltage on the field winding is substantially reduced, and the dynamic voltage deviation of the generator does not exceed 5%. Voltage transients to the load close to an invariant.
