Problems solved by technology

The issuance of the secondary safety ticket is manually filled out by the operation and maintenance personnel, which will easily cause missing items and missing items, which is not conducive to the safe operation of the power grid
The present invention solves the problems that the traditional manual preparation of the secondary security ticket is difficult and error-prone, and there is no system management for the secondary security ticket, but it only provides a method for automatically issuing the secondary security ticket. In practical applications, It is also necessary to print out and sign the secondary security measure ticket issued by it or perform secondary security measures against the secondary maintenance security measure ticket in the electronic file, which partially improves the efficiency of operation and maintenance, but does not affect the actual operation and maintenance. make any improvements

Abstract

The invention discloses a method for implementing safety isolation measures in maintenance of intelligent power station relay protection equipment, which is applied to a handheld terminal and comprises the steps of substation information configuration, secondary circuit display, secondary safety measure ticket automatic generation, system parameter configuration, communication mode setting and relay protection maintenance, wherein the relay protection maintenance comprises the steps of secondary safety measure ticket selection; safety measure execution, namely, sequentially executing and automatically checking according to a preset secondary safety measure ticket step sequence, wherein the automatic checking refers that the system automatically judges whether the currently executed safetymeasure step is executed successfully or not, and the judgment basis is whether the current states of all soft pressing plates associated with the current safety measure step are consistent with an expected result set when the secondary safety measure ticket is automatically generated or not; automatic safety measure recovery; and anti-error checking. The invention further provides a method for implementing safety isolation measures in maintenance of the intelligent power station relay protection equipment. According to the invention, the safety measures can be automatically implemented according to the secondary safety measure ticket, and the system faults can be automatically and accurately analyzed, thereby having a huge application market.

Description

technical field [0001] The invention relates to the technical field of operation and maintenance management of power grid intelligent substations, and specifically belongs to the technical field of secondary maintenance safety measures. Background technique [0002] The relay protection device occupies an important position in the secondary equipment of the power system. It reflects the abnormal operating conditions and accidents in the power system, and acts on signaling or tripping, so that the abnormal operating conditions can be adjusted in time, or the fault point can be removed in time. When the relay protection device refuses to operate or malfunctions, it often causes the accident to expand, and even causes a large-scale power outage. Therefore, it is very important to do a good job in the inspection and testing of the entire protection device to ensure the correct and reliable operation of the relay protection device. [0003] At present, my country has accelerate...
