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, and belongs to the technical field of distribution network line management. The method is based on an SCADA system, a PMS power grid production management system and an operation safety risk management and control system. The method comprises seven steps. Multivariate data fusion is used in the monitoring of thepower failure state of a 10KV line. Precise power failure monitoring is achieved, the electricity loss due to power failure is accurately calculated, and the statistical efficiency and accuracy are greatly improved. The year-on-year reduction of the number of non-planned outage 10KV lines is 21.7%, the year-on-year reduction of power failures is 32.4%, and the year-on-year reduction of the electricity loss due to power failure is 6.636 million kilowatt-hours. Power failure approval monitoring and power failure and power transmission process management are enhanced through accurate monitoringdata, so that there is reference data for key nodes of planned power failure, and the management level is improved. The problems of long data statistics period, poor integrity and incapability of calculating electricity loss due to power failure in an existing mode of reporting and summarizing the power failure data step by step in each team are solved.

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...
