Sistema supervisório aplicado a subestações digitais

Abstract

Substations are an integral component of power grids, they connect electrical grids of different voltage levels, and their control and coordination function is vitally important for the stability of the system as a whole. Its digitization is a decisive step in successfully shaping the transformation of energy systems. One reason for digitizing a substation is that it allows for much more cost-effective operation over its lifecycle - from planning and operation to service. A digitized substation also increases the availability, reliability and sustainability of the entire power supply. An extremely important part that integrates the entire digitalization process of the substations is the supervisory system; system that allows the interaction of the operator with the entire structure of the substation, in addition to its supervision, including the supervisiono f the electrical and mechanical equipment constituting the network, sensors and alarms. The present work presents the development of the supervisory system for a digital substation. The development of this system involves the creation and modification of the visualizations, guaranteeing the operator, greater ease of use and visualization of the representation of the substation as a whole. In addition, the work presents the tests carried out to guarantee the proper functioning of certain functions created in the HMI.
