Problems solved by technology

[0009] In view of this, the purpose of the present invention is, before the monitoring terminal is connected to the power quality online monitoring system, to carry out consistency definition and rapid detection on the PQDIF data format of each equipment manufacturer, and judge whether it meets the requirements of accessing the current online monitoring system, This solves the problem that when different manufacturers implement the PQDIF specification, there will be inconsistent definitions of channel label sets or sequence label sets, which will hinder the promotion of the PQDIF standard, and provide technical support for the construction of a compatible and unified power quality integrated data platform

Embodiment Construction

[0077] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0078] In the embodiment of the present invention, the PQDIF file is taken as an example for illustration. For example, the channel label and sequence feature are respectively obtained from the data source record of the PQDIF file, and the sequence value is obtained from the observation record of the PQDIF file for detection respectively. However, those skilled in the art It should be understood that as long as the different data exchange formats stipulated in other standards conform to the spirit of the present invention, they should also be included in the protection scope of the claims of the present invention.

[0079] Detailed exemplary embodiments are disclosed below. However, specific structural and functional details disclosed herein are merely for purposes of describing example embodiments.

[0080] It should be understood, however, that the invention is no...

Abstract

The invention discloses a detection method for power quality monitoring data. The method includes the following steps that A, the power quality monitoring data are acquired from a power quality monitoring terminal, and one or more steps of the step B, the step C and the step D are executed; B, a channel label is acquired from the power quality monitoring data, and the channel label is compared with a prestored standard channel label; C, a sequence property is acquired from the power quality monitoring data, and the sequence property is compared with a prestored standard sequence property; D, sequential value error detection is conducted on the power quality monitoring data; E, the comparison and / or detection results of one or more steps of the step B, the step C and the step D are fed back to a power quality analysis server, data which meet the on-line monitoring system requirement are analyzed and then stored into a foundation database, serving as advanced calculation basic data, the data which cannot meet the requirement are fed back to the monitoring terminal, and a PQDIF file is generated again according to the standard definition. By the adoption of the method, the detection data of the monitoring terminal can be detected quickly, and screening of the monitoring terminal can be simplified.

Description

technical field [0001] The invention relates to the field of power system equipment, in particular to a power parameter detection technology. Background technique [0002] Power quality monitoring is the premise for the power company to understand the performance of the power system and make it meet the needs of users. It is the first step to analyze and solve power quality problems. The technical and data basis to achieve the power quality level agreed in the contract. [0003] For a long time, the power quality online monitoring system has mostly established a small-scale data center based on a certain manufacturer's monitoring terminal, and there is no unified standard. This will lead to different background analysis software of different power quality monitoring equipment, and data incompatibility between them. At the same time, power quality monitoring and analysis involves a wide range of data sources. If the contents and description formats of different types of dat...
