DISTRIBUTED GENERATION SYSTEM WITH IMPROVED NETWORK POWER QUALITY

摘要

A distributed generation system with improved electrical network power quality, of the type which supplies electrical power in a distributed model, and which can inject and absorb active and reactive power at the network by means of filters and power transformers, so as to compensate for different disturbances; it being comprised of a direct current generator, a direct current-direct current converter; a means for storing power with a high response speed connected in parallel; and a direct current-alternating current inverter which generates three-phase alternating current from the power supplied by the generator. The voltage of the inverter is controlled by means of a vectorial control which continuously samples the parameters of the network in order to adjust, with a high response speed, the amounts of active and reactive power which the system must exchange with the electrical network in order to eliminate or reduce these disturbances.
