This paper provides the description of power system control during emergency situations applying new stability control method, which is based on determination of controlling actions using real emergency state of power system. Development of power systems, appearance of large interconnected power systems with thermal and hydro power plants of large capacity, as well as loaded power transmission lines complicates control tasks of operational conditions. Effective tools for providing power system stability are the anti-emergency automation, which contains various numbers of arrangements preventing expansion of emergency disturbances and their spreading out to neighbouring regions of power system [1]. Existing anti-emergency automation prevents power system stability disturbance using pre-calculated emergency situations and providing dosed control impacts on power system generation and load in order to restore power balances and prevent dangerous overloading of transmission lines. However, not all emergencies can be foreseen in advance. Therefore, there is a need in development of control automation adaptive to any possible emergency situation.
