METHODS OF DIGITAL SIGNAL PROCESSING BY MICROELECTRONIC DEVICE OF RELAY PROTECTION OF HIGHVOLTAGE POWER LINES

The fast-acting algorithms of exposure and invariant authentication of transients are worked out in the lines of electricity transmission as load surge, short circuits and start of powerful electric engines on the basis of that the functions of device of relay defence of high-voltage lines of electricity transmission. The given structure of small, microelectronic fastacting device of relay defence is with the extended functional possibilities of recognition of load surge and defence of high-voltage lines of electricity transmission from short circuits, the syntax of his functions is carried out. This device can be used for recognition of load surge and short circuits of invariant to the size of increase currents in the separate phases of electric lines. It allowed successfully to apply the worked out method and device for simultaneous recognition of load surge, short circuits and starting of powerful electromechanics engines. The information technology of designing structural solutions of relay protection special processor for high-voltage electricity transmission lines is presented.
