METHOD OF RELAY PROTECTION OF POWER INDUSTRY FACILITY Russian patent published in 2012 - IPC H02H3/40 

FIELD: electricity.

SUBSTANCE: according to the method, the relay protection structure consists of two diverse modules. Modules of the first type generate a tripping signal while modules of the second type generate an enabling signal. The protection undergoes a training cycle in controlled and alternatively controlled modules. With the help of imitation modes the power industry facility operation modes are converted to corresponding measurements on 2D signal planes. Introduced into the system are hierarchic groups of modules of the first and the second type. Within a hierarchic group modules of the first or the second type are joined through AND gates. All the hierarchic group are joined through an OR gate. Given is implementation of the protection structure in case of its recurrent and recursive training on multiple 2D signal planes.

EFFECT: extension of functional capabilities combined with simplification of the method.
