Abstract

The invention discloses a transformer substation secondary equipment reliability management system and method based on event recording. The method comprises the steps of: firstly, collecting history data of transformer substation secondary equipment event recordings, and setting a starting time and an ending time of a statistics period; secondly, retrieving the event recordings in the statistics period of transformer substation secondary equipment and forming a directory; then respectively calculating the shutdown time of the transformer substation secondary equipment according to the number of the event recordings in the statistics period; calculating an equipment available rate of the transformer substation secondary equipment in the statistics period; then calculating the percentage of non-planned shutdown time of the transformer substation secondary equipment in the statistics period; and finally forming an electronic document of the equipment available rate of the transformer substation secondary equipment in the statistics period and shutdown classification statistics. According to the invention, by reading the event recordings of the transformer substation secondary equipment in the statistics period and carrying out classified statistics, the equipment available rate of the transformer substation secondary equipment in the statistics period is calculated, and the electronic document is formed, so that reliability assessment of the electric power system secondary equipment is realized; in addition, the system and the method are used for guiding the construction and maintenance of an electric power system, so that the purpose of fine management is achieved.

Description

technical field [0001] The invention belongs to the technical field of substation automation, and in particular relates to a reliability management system and method for substation secondary equipment based on event records. Background technique [0002] At present, the reliability analysis of substation secondary equipment is mainly based on the statistical analysis of equipment operation, and there are various human factors, which may easily cause distortion of equipment reliability analysis. Record of Events (SOE) is the sequence of events record. When the remote signal displacement of the electric equipment occurs, such as the switch displacement, the power protection equipment or the intelligent power meter will automatically record the displacement time, the cause of the displacement, and the corresponding remote measurement when the switch trips. Values ​​(such as corresponding three-phase current, active power, etc.) form SOE records for post analysis. Many relay pr...
