The article consideres the problem of extraction of maximum energy from a solar panel in an autonomous power supply system working with renewable sources under the condition of constant joint operation of a solar panel and a diesel generator. It is proposed to solve the problem taking into account the nonlinearity of the external characteristics of energy sources.
Investigation of electromagnetic and electromechanical processes, which take place in the autonomous power supply system based on asynchronised generator with three phase modulated exciter, was conducted by means of mathematic experiment. The processes in terms of work suitableness of power supply system during its work at the junction of asynchronous motors and active-inductive load were analysed. Regularities of electromagnetic and electromechanical processes, depending on the schedule of consumers’ work and system of commutator management parameters were determined.
