Impacto do produtor independente de energia elétrica em rede de distribuição uma análise através do ATP-EMTP

Abstract

This work presents a performance analysis of an Independent Producer synchronous generator, with its voltage and speed governors, running connected in parallel with a power authority distribution system. This synchronous generator is driven by a steam turbine and the whole system has been modeled in ATP-EMTP (Alternative Transients Program) through the use of TACS routines. The technical questions studied are the steady-state voltage profile, voltage stability, voltage sags and load rejection, partial loss of the distribution line in the interconnection as well as excitation and speed control performance to contingencies in the interconnected system. Results show that, in some cases, the independent generation can be a menace to the physical integrity of the system and in other cases can be very beneficial to the distribution system in the point of connection.
