Filed: 1987-03-25
Abstract: PURPOSE:To decrease a calculation quantity, and also, to improve a recognition rate by using 4 components of a stroke and 4 components of a background as a vector-converted feature quantity. CONSTITUTION:As for a stroke component, a stop/propagation processing is omitted, and a vector-converted result 11 becomes a final vector component 21 by collecting the component whose situations are opposite, in the same direction, to one.

Abstract: PURPOSE:To prevent erroneous output without delaying responding time for an internal accident in a protected region by a method wherein the title device is provided with a lock means, arranged between a time limit operation instantaneous returning timer and an instantaneous operation time limit returning timer and operated based on the operation of a current relay. CONSTITUTION:When a ground fault occurs out of a protected region, a reactance type distance relay 44X outputs a signal SX0, shifted from High to Low. On the other hand, an alteration width overcurrent relay 8 detects that the change of an input current becomes higher than a predetermined value and outputs a pulse signal while a monostable multivibrator 63 for locking outputs a pulse signal SC from this time point. On the other hand, the waveform of a signal SM2, one of inputting signals into an AND circuit 71 and being shifted from Low to High, is obtained from the output signals SM0, SM, SM1, SM2 of a mho type distance relay 44M. A signal S0 as the result of the AND of a signal SX2 and the signal SM2, which is obtained by the AND circuit 71, does not generate any erroneous output by this method.
