Resumen
In this work develops the thermal damage curve for 132 kV conductors in transient state with the aim to propose the overload settings implemented in the overcurrent function, because there is the possibility that in electrical system present old protection equipment that does not have an overload function. The study is based on the research for a real case of the Provincial Interconnected System (PIS) of San Juan, Argentina. The PIS has a particularly conflictive node where a large amount of conventional hydroelectric generation and PV plants with approximately 300 MW are concentrated. During the study, overloads were found in the lines that exceed the damage curves of the conductors, so due to this, adjustments of the overload setting in the overcurrent function are proposed to avoid irreparable damage. At the same time, the possible schemes automatic generation disconnection (DAG) are analyzed as alternatives to conductors overload scenarios, considering that the photovoltaic generator can be disconnected in case of fault conditions, and when it remains connected to the system, it will not inject reactive power, because currently there is not requirement on the part of the coordinating entity CAMMESA.
