Problems solved by technology

[0003] The traditional intrusive load detection method directly collects independent data of the operating load, and then performs detection based on the collected data. Although the obtained load information is true and reliable, it requires a large number of equipment and high cost, and its installation and maintenance are of great importance to load operation. The impact is relatively large, so it is not suitable for industrial load event detection

Embodiment 1

[0062] In the following embodiments, in order to distinguish the difference between the data segments in step S2 and step S5, the data segment intercepted in step S2 is called the first data segment, and the data segment intercepted in step S5 is called the second data segment. In addition, the load events in the present invention include load state change events and load mode change events; the events of slow and large changes in power signals caused by load switching actions are recorded as load state change events; Events in which the constant power signal changes regularly are recorded as load pattern change events.

[0063] Such as figure 1 As shown, the present invention discloses a non-intrusive industrial load event detection method, the method comprising:

[0064] Step S1: Synchronously collect power consumption data from the power meter of industrial users through a non-intrusive collection device to form a first power consumption data set.

[0065] Step S2: Interc...

Embodiment 2

[0141] Such as figure 2 As shown, the present invention also provides a non-intrusive industrial load event detection system, the system comprising:

[0142] The first electricity consumption data set construction module 201 is used for synchronously collecting electricity consumption data from the power meter of industrial users through a non-intrusive collection device to form a first electricity consumption data set.

[0143] An average power difference calculation module 202, configured to intercept N adjacent first data segments from the first electricity consumption data set, and calculate the average power difference between any two adjacent first data segments; Wherein, N is a positive integer greater than 2.

[0144] The load state change event determination module 203 is configured to determine whether a load state change event occurs according to the average power difference corresponding to two adjacent first data segments.

[0145] The second power consumption ...

Embodiment 3

[0167] Such as image 3 As shown, a non-intrusive acquisition device is installed at the low-voltage side power meter of a steel plant to collect voltage waveform and current waveform signal data. The sampling rate is 5000Hz and the collection time is 60 minutes.

Abstract

The invention relates to a non-intrusive industrial load event detection method and system, and relates to the technical field of intelligent power consumption management, and the method comprises the steps: synchronously collecting power consumption data through a non-intrusive collection device to form a first power consumption data set; intercepting N adjacent first data segments from the first power utilization data set, and calculating an average power difference value between any two adjacent first data segments; determining whether a load state change event occurs or not according to the average power difference value corresponding to the plurality of adjacent two first data segments; constructing a second power utilization data set according to the detected load state change event; intercepting M adjacent second data segments from the second power utilization data set, and calculating an intersection point number difference value between any two adjacent second data segments; and determining whether a load mode change event occurs or not according to the difference value of the number of intersection points between the plurality of adjacent second data segments, thereby realizing industrial load event type detection.

Description

technical field [0001] The invention relates to the technical field of intelligent power consumption management, in particular to a non-invasive industrial load event detection method and system. Background technique [0002] The goals of carbon peaking and carbon neutrality put forward new requirements for low-carbon and energy-saving industrial development, and urge industrial users to continuously improve production energy efficiency. Industrial production consumes a lot of electricity, and the electricity consumption data of its load can largely reflect the actual situation of the factory's production operations. Therefore, in industrial production, it is necessary to monitor load electricity consumption information, and then obtain user production conditions and restore load actions, which can help industrial users improve production energy efficiency and achieve low-carbon transformation. [0003] The traditional intrusive load detection method directly collects indep...
