Problems solved by technology

[0005] However, at present, the data specifications of various power quality monitoring device manufacturers have not formed a unified standard, resulting in the incompatibility of the acquired power quality data, forming an information "island" of power quality data, which greatly increases the utilization and processing costs of power quality data

Embodiment 1

[0029] This embodiment provides a method for processing power quality data, see figure 1 , the method flow provided by this embodiment is specifically as follows:

[0030] S101. Acquire real-time monitoring data of electric energy from the electric energy monitoring equipment.

[0031] The electric energy monitoring device is a device for collecting real-time electric energy monitoring data, and the real-time electric energy monitoring data includes at least the identification of the second electric energy monitoring device and the corresponding original data of electric energy quality. At present, the formats of raw power quality data collected by power monitoring equipment produced by different manufacturers are different, and the raw data of power quality are incompatible with each other.

[0032] Wherein, the electric energy monitoring equipment identification is the identification information that can uniquely distinguish the electric energy monitoring equipment, for exa...

Embodiment 2

[0055] This embodiment provides a method for processing power quality data, see figure 2 , the method flow provided by this embodiment is specifically as follows:

[0056]S201. Acquire real-time power monitoring data from a power monitoring device, where the real-time power monitoring data includes a second power monitoring device identifier and corresponding raw power quality data.

[0057] S202. Obtain the original electric energy data parsing rules matching the current electric energy real-time monitoring data from the preset electric energy monitoring model.

Abstract

The invention, which belongs to the field of the power grid technology, discloses a processing method for electric energy quality data. The method comprises the following steps: obtaining real-time monitoring data of the electric energy from electric energy monitoring equipment; generating the real-time monitoring data of the electric energy into target electric energy quality data according to a preset electric energy monitoring model; and analyzing the electric energy quality according to the target electric energy quality data. According to the invention, the electric energy real-time monitoring data obtained by the electric energy monitoring equipment are generated into the target electric energy quality data with the unified format and specification based on the preset electric energy monitoring model, so that a phenomenon of an electric energy quality data information islet due to mutual incompatibility of data formats and thus the utilization and processing cost of the electric energy quality data can be substantially lowered.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and device for processing power quality data. Background technique [0002] Power quality refers to high-quality power supply in a general sense, including voltage quality, current quality, power supply quality and power quality. It can be defined as: the deviation of voltage, current or frequency that causes user equipment to malfunction or not work normally, and its content includes frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase unbalance, temporary or transient overvoltage, waveform Distortion, voltage dips, interruptions, swells, and continuity of power supply. [0003] At present, various types of non-linear, impact and asymmetric loads in the power system are continuously increasing, making power quality problems such as harmonic pollution, three-phase voltage unbalance, voltage fluctuation and flicker in the power grid mo...
