The principles of operation, the basics of microelectronic, analog and microprocessor integrated implementation of automatic control devices for normal operation of electric power systems and emergency management of them. Normal mode automation includes: software start-up, Synchronization, regulation of speed and active power and regulation of excitation of synchronous and asynchronous generators , voltage and reactive power of synchronous and static controlled compensators and transformers microprocessor implementation of automated power plant control systems , Power Systems , their associations and the Unified Electric Power System . Anti-emergency automation is provided by automatic re-activation devices, automation to prevent the violation of the stability of power systems and the elimination of asynchronous mode , limitations of changes in regime parameters in weighted and emergency situations and modern integrated microprocessor automation.
