The Control System of Group Synchronous Generators with Different Power

The article focuses on interaction of several electricity sources combined into a microgrid. The article shows scheme of autonomous power supply based on a several permanent magnets synchronous generators. A feature of the scheme is the different nature of the rotors rotation. The authors, based on already known studies, note the possible occurrence of problems and tasks. The distribution of currents between the converter modules is the main problem due to the uneven power generated. This problem arises due to the difference in the speed of rotation of the generators. The authors propose to solve this problem using an control system algorithm based on comparing the actual current value at the output of the permanent magnets synchronous generators with the average current value on the DC bus. The created simulation model in MATLAB environment with Simulink extension package is considered. The model allowed to research of transient processes. The results of investigation of the simulation model when changing rotation speed of the generator drive shaft are given.
