FIELD: electricity. ^ SUBSTANCE: present invention relates to power engineering, particularly to uninterrupted power supply to users, connected and not connected to a single power system, as well as to systems working with renewable energy sources, with different parametres of output voltage. Proposal is given of coupling renewable energy sources with accumulator batteries, providing voltage through a converter. When power supply from the network is interrupted, the load is connected to an ac voltage generator, automatically driven by an internal combustion engine. The given voltage value is applied across the load through a voltage stabiliser. ^ EFFECT: more reliable power supply to users. ^ 2 cl, 1 dwg |
