Adaptive Protection Systems

Abstract

Sustainable resources would replace traditional energy production solutions in the near future. There are determinant factors that force to adopt the changes in actual power system: environmental protection, and the increasing price of natural gas, coal and oil. The chapter provides a short overview of protection functions in adaptive systems. Nowadays, the alternative energy sources forced the power system to support major transformations. The energy producers or medium voltage (MV) electricity market operators through remote controllable line disconnectors achieve new technology in distribution power systems. The remote-controlled recloser is one of the most important equipment used in MV distribution systems. The chapter contains the most features of the remote-controlled recloser. The adaptive protection of a distributed system is based on the Loop Automation Scheme, described largely by the authors. The main advantage is the restoration of energy supply to consumers in minimum time. The chapter includes a case study in the Galati distribution operator activity area (Romania).
