Problems solved by technology

The sampling value service of the digital substation is related to the safe operation of the system. Any error in the operation and maintenance process may lead to abnormal behavior of the substation, causing huge economic and property losses, and even personal casualties.
In current substations, especially high-voltage substations, there are a large number of devices, and the first and second disconnections are complicated. There is an urgent need for a method to improve the reliability of operation and maintenance. overall reliability

Abstract

The invention discloses a method for improving the reliability of operational overhaul of a transformer substation, which is characterized by comprising the following steps: (1) acquiring an overhaul or simulated state of a sampling link and a quality state of a sampling channel in real time, and computing the magnitude of current of a current channel; (2) acquiring the control information of a running state of the sampling link in real time; and (3) comparing the control information of the sampling link with the real-time acquired sampling and computing result in the step (1) so as to actively identify the faulty operation of operational overhaul. By acquiring and computing the related data information of the sampling link in real time and acquiring the control information of the running state of the sampling link in real time, the faulty operation of operational overhaul of the transformer substation can be effectively prevented and corresponding caution information can be provided, thereby improving the reliability of operational overhaul of the transformer substation and further effectively avoiding the huge economic property loss.

Description

technical field [0001] The invention relates to a method for enhancing the reliability of substation operation and maintenance. Background technique [0002] In the digital substation, the digital substation sampling value transmission technology based on the sampling value service of the IEC61850 standard has been widely used. The sampling value control block is the basis of information transmission in the sampling value service, and each sampling control block information received by the sampling receiving device is called a sampling link. Each sampling link can simultaneously transmit multiple current and voltage sampling channels. Wherein, each sampling channel includes a piece of data and a piece of quality information, and the sampling quality information indicates status information of the channel data. Each sampling link includes a status flag, which is called the inspection / simulation flag in the first edition / second edition of IEC61850, which is used to indicate ...
