A line current i(k) of an M side of a first direct-current transmission line is collected at a moment k. A line current i(k−t) thereof is collected at k−t. At a moment k, a differential value di(k) of a current of the side of the first direct-current transmission line is calculated according to the line current i(k) and the line current i(k−t). It is determined whether the differential value di(k) of the current meets a protection enabling criteria. If so, direct-current protection for the M side of the first direct-current transmission line is enabled. A line current i(j) of the M side of the first direct-current transmission line is collected at a moment j. A line current i(j−t) thereof is collected at a moment j−t. A differential value di(j) of the current of the M side of the first direct-current transmission line at the moment j is calculated according to the line current i(j) and the line current i(j−t).

Direct-current transmission line protection method and system based on pure current characteristics

A method and device for timing in time-varying distance protection based on multiple lines of a tower. The method includes: collecting an instantaneous current value at a time-varying distance protection installation location in the multiple lines of the tower, and acquiring preset parameters; calculating, according to the preset parameters and a multi-line ranging model, a multi-line ranging result; calculating, according to the preset parameters, the multi-line ranging result, and an adaptive calculation model, time of a section-II distance protection action and final time of a section-III distance protection action; and determining, according to the instantaneous current value, the preset parameters, and a cross-line failure auxiliary criterion model, final time of the section-II distance protection action.

The present invention disclosed a method and system of replacing smart cards. It uses a new identification device (a new SIM) to replace an old one (an old SIM) associated with a user account. The new identification device has an identification number (ICCID). The new identification device is activated in the following manner. The old identification device communicates with an identification-management center through a communication interface (mobile telephone). And the identification-management center recognizes the old identification device. The identification number of the new identification device is sent to the identification-management center through the communication interface. The identification-management center checks the identification number. If the identification number is correct, the user account will be assigned to the new identification device by the identification-management center.
