FIELD: electrical engineering.
SUBSTANCE: invention can be used in electrical engineering for creation of automatic distributed load disconnection systems. According to the method, the power system model is constructed, overloaded links are separated between the power districts and the control action vector is determined, wherein elements of the current distribution coefficient matrix are pre-determined for each topological state of power districts with allowance for the load and are stored in the memory of the anti-accident control system, transmitting, by means of dispatcher-technological control, data on driving currents for determining current modes of power districts and topological states of their electrical circuits, current vectors of the driving currents of the control actions and matrix of current distribution coefficients are used to calculate branches currents of power circuits of power districts, rational versions of anti-accident control are formed, after which data on rational variants of emergency control in memory of the anti-accident control system are entered and in case of exceeding of permissible values of power district electric circuit branching, information on rational variants of anti-accident control is read and control action vector is determined, which in the form of control commands is transmitted to final devices for implementation of control commands and load disconnection of power system.
EFFECT: simple method and faster operation thereof.
