Problems solved by technology

[0004] At present, there are oil chromatography online monitoring systems on the market, each manufacturer has its own design and implementation, but there is no good processing method for the validity of the sampling data, and a set of data can only be proved by comparing the offline data with the offline laboratory is it effective
[0005] The data comparison with the offline laboratory has its limitations, that is, the data obtained can only be compared by the laboratory staff and the oil chromatography online monitoring system at the same time; for the long-term operation of the oil chromatography online monitoring system, It is obviously not operable to compare offline and online data at any time, so it is very important to invent a method that can automatically analyze and judge the validity of online monitoring data of oil chromatography

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] Such as figure 1 As shown, the detection method of oil chromatographic on-line monitoring data validity of the present invention comprises the following steps:

[0018] 1) The sensor array monitors the gas concentration in the oil online, and continuously sends relevant data to the online monitoring system;

[0019] 2) The online monitoring system judges whether the data is abnormal; if there is no abnormality, then continue to detect the next set of data; if the data is abnormal, further judge whether the data conforms to the principle of gas in oil;

[0020] 3) If the data does not conform to the gas-in-oil generation principle, it is judged that the equipment status is abnormal, and the abnormal data of this group is judged to be inva...

Abstract

The invention discloses a method for detecting the effectiveness of oil chromatogram online monitoring data. According to the method for detecting the effectiveness of the oil chromatogram online monitoring data, the effectiveness of abnormal data is automatically analyzed and judged by combining oil fault types of GB / T-7252-2001 standard and a sensor array, namely a system can automatically analyze and judge the effectiveness of the monitored abnormal data, and can effectively determine the effective monitoring data. The effectiveness, accuracy and reliability of data of an oil chromatogram online monitoring system can be improved.

Description

technical field [0001] The invention relates to the field of online monitoring of oil chromatography, in particular to a method for detecting the validity of online monitoring data of oil chromatography. Background technique [0002] At present, in the power system, the system for on-line monitoring and analysis of transformer oil is widely used. In the smart substation technology, the oil chromatographic on-line monitoring system has become a monitoring item that must be used for new and operating transformers. Guaranteeing the normal operation of the power grid plays an important role, so how to ensure the validity of the online monitoring data of oil chromatography has very positive practical significance. [0003] Oil chromatography on-line monitoring system is a device for monitoring the content of dissolved gas components in transformer insulating oil. It is used to help users monitor and warn whether there are latent overheating, discharge, insulation and other faults...
