The article discusses the reliability of various automation systems while maintaining a normal voltage level in the nodes of the power system. The main attention is paid to the installation of an automation subsystem for limiting voltage reduction, for which control actions are considered for shutting down shunt reactors, switching on capacitors, boosting and increasing the excitation settings of the SC and generators of the station, and switching off the load. The introduction of automation for limiting voltage reduction does not require significant material costs, making switching off the load a very attractive way to increase the reliability of power supply in megacities.
