In response to the growing importance of power system security and reliability, qTransmission Grid Securityq proposes a systematic and probabilistic approach for transmission grid security analysis. The analysis presented uses probabilistic safety assessment (PSA) and takes into account the power system dynamics after severe faults. In the method shown in this book the power system states (stable, not stable, system breakdown, etc.) are connected with the substation reliability model. In this way it is possible to: estimate the system-wide consequences of grid faults;identify a chain of events that might lead to blackout; andrank the importance of different substation components at the system level. qTransmission Grid Securityq also presents the main features and basic mathematics of PSA. It provides the reader with up-to-date knowledge of the regulatory issues affecting the security of transmission grids in Europe. qTransmission Grid Securityq gives a practical method for the security analysis of transmission grids, making it a valuable text for engineers and system operators, as well as postgraduate students. It includes basic information and detailed modules for creating a reliability model that takes into account all the basic operations and components needed after grid faults.At LE2, the relays fail to send an instantaneous trip signal (POTT), but they send a delayed zone trip signal after which the circuit breaker trips correctly. The fault duration at LE2 is the delay of zone 2 and circuit breaker operation time, anbsp;...
