Embodiment

[0040] Embodiment: (The following PMS power grid production management system is referred to as PMS system for short)

[0041] (1) Data collection, filtering and cleaning: collecting and dispatching SCADA system remote signaling and telemetry information through the development interface; matching the PMS system equipment basic files through background batch export; using the operation safety risk management and control system weekly plan, daily plan, etc. filter the data;

[0042] (2) Judgment of rules: Comprehensively judge power failure based on the two conditions of 10KV line switch displacement and current mutation: When the 10KV line switch changes from closing to opening, and the current drops by more than 80% before and after opening, the line status is determined In case of a power outage, record the opening time as the start time of the power outage. When the 10KV line switch is opened this time, the SCADA system and the PMS system monitor the closing information be...

Abstract

The invention relates to a multivariate data fusion 10KV line state monitoring method, which belongs to the technical field of distribution network line management. Based on the SCADA system, the PMS power grid production management system and the operation safety risk management and control system, through the method of the present invention including seven steps, the fusion of multiple data is used for the monitoring of the power outage status of the 10KV line, so as to realize accurate monitoring of power outages and accurate calculation of power loss due to power outages, greatly improving Statistical efficiency and accuracy have reduced 10KV unplanned outage lines by 21.7% year-on-year, the number of power outages has decreased by 32.4% year-on-year, and the power loss due to outages has decreased by 6.636 million kWh year-on-year. Strengthen the monitoring of power outage approval and power outage transmission process management through accurate monitoring data, so that there are "numbers" to rely on for each key node of the planned power outage, and the management level is improved. It solves the problem that the existing statistical power outage data of each team is reported step by step and then summarized, the data statistics cycle is long, the integrity is poor, and the power loss due to power outage cannot be calculated.

Description

technical field [0001] The invention relates to a multivariate data fusion 10KV line monitoring method, which belongs to the technical field of distribution network line management. Background technique [0002] Many 10KV distribution network lines are erected in the jurisdiction area of ​​the State Grid prefecture-level power supply company. These 10KV distribution network lines undertake the heavy responsibility of power supply in urban areas, suburbs, rural areas, factories, and enterprises in the area, whether it is regular maintenance and expansion construction Planned power outages or unplanned power outages caused by line failures and sudden accidents will have a major impact on people's production and life, especially agricultural production and electricity consumption. Therefore, it is necessary to manage the power transmission process of the 10KV distribution network line. At present, the power outage data in the power outage process of the 10KV distribution netwo...
