The paper analyses the reliability of power supply for a 330/750 kV electrical ring. Consideration is also given to the influence of emergency automatics on the maximum permissible power flows in different electrical connection points of the ring as well as to the application of reliability criterion (N-1) in the case of using the emergency automatics to limit post-accident power flows in these points. The authors discuss the role of operative and technological management in securing the power supply reliability. They also analyze situations with disconnection of major generation units and its influence on the blackout development.
