The most common way to monitor the state of distributed power facilities is periodic polling, which is carried out regardless of the current state of the facilities and their changes in adjacent time cycles. This method leads to a significant decrease in the speed of information exchanges, especially in the event of accidents, which makes it necessary to develop new approaches to processing emergency information. In this work, a sporadic method of processing emergency information for control systems of distributed power facilities is considered. The procedure for calculating the intensity of information flows is presented and the average load of the center processing the stationary stream of the remote signaling - remote control channel with cyclic method of data input is determined. Analysis of the intensity of remote signaling - remote control channel stationary flow showed that the processing center does not experience any significant difficulties in its maintenance. The intensity of the emergency generalized flow of the channel was analyzed and the processing center ability to serve the specified flow without delay was evaluated, for the maintenance of the peak flow of emergency information is the main quality criterion for control systems of complex distributed power facilities. It has been mathematically substantiated that the intensity of the emergency flow of the remote signaling - remote control channel is higher than the permissible values. It has been demonstrated that the proposed sporadic method of processing emergency information makes it possible to only transmit data in case of significant events, e. g. change in the state of the monitored object (remote signaling), measured parameter run-out beyond the aperture, which reduces the number of uninformative requests. The use of the developed method of emergency flow intensity reducing based on the use of the proposed sporadic method of data entry provides a 5-fold reduction in the processing center load.
