FIELD: electrics.
SUBSTANCE: method of power supply to separate electric collector group involves power supply from additional autonomous mutually backed up power source positioned in direct vicinity from the group and, while power supply to the other electric collectors (including special electric collector group responsible for accident-free halt) not critical not reference parametre deviations is implemented by two autonomous mutually backed up external power sources. Autonomous power source is main source for separate electric collector group of continuous production process, its parametres are set with reliability probability and power value equal to ones of given electric collector group, and connection state between external and autonomous power sources is constantly monitored.
EFFECT: improved reliability of power supply, materials and power saving.
