Description
Summary:The main task in this paper is to present a performance analysis of a distribution network in the presence of two synchronous generators in parallel, with its speed and voltage regulators modeled with TACS - Transient Analysis of Control Systems, for distributed generation studies. This type of configuration is common in systems where renewable fuels are used as sugar cane bagasse or straw. Must be highlighted that these generators are driven by steam turbines, and the whole system with regulators and the equivalent of the power authority system in the point of connection (CCP - Common Coupling Point) are modeled in the "ATP-EMTP - Alternative Transients Program". Technical questions studied here refer to steady-state voltage profile, voltage stability, voltage dip due to a balanced three-phase fault, load rejection, distribution line outage and the behavior of machine regulators facing the aforementioned contingencies. Results show that, in some cases, the independent power producer (IPP) can be a risk to the physical integrity of the system and in other cases can be very beneficial to the distribution system in the point of connection.
