Real-time scanning and update push method of converter station monitoring fault alarm information

Abstract

The invention discloses a real-time scanning and updating push method for monitoring fault alarm information of a converter station. An intelligent scanning system is used to capture equipment data messages on a monitor screen of a converter station, and images and characters are preprocessed. Characters are recognized by template matching method, similar characters are judged, structural feature extraction is performed on the similar characters, the similar characters are distinguished, the characters that meet the conditions are output, and the content of the characters is stored in the computer memory for reporting. Message update push processing, message push, new message judgment, new message push, execution ends. The invention realizes the timely and accurate push of the equipment status information of the converter station, improves the effect of the operation and maintenance personnel in dealing with the faulty equipment, reduces the work intensity of the operation and maintenance personnel, and helps to ensure the health and safety level of the equipment.

Description

technical field [0001] The invention relates to the technical field of power system dispatching control, in particular to a method for real-time scanning and updating push of converter station monitoring fault alarm information. Background technique [0002] With the vigorous development of information technology in today's era and the increasing sophistication of artificial intelligence technology, information push update technology has been widely used in national security, traffic processing, public safety and most civilian enterprises. [0003] The DC converter station is mainly responsible for the mutual conversion of AC and DC power in the power system, and its stable operation is crucial to the safety of the power grid. The operating status and various faults of the equipment in the DC converter station are changeable, which requires the staff to monitor in real time according to the display screen of the converter station monitoring center. Due to the limited informa...

AI Technical Summary

Problems solved by technology

The operating status and various faults of the equipment in the DC converter station are changeable, which requires the staff to monitor in real time according to the display screen of the converter station monitoring center. Due to the limited information transmission channels at present, it cannot be guaranteed by relying on the management of the staff. All kinds of faults are detected and dealt with in time, and long-term monitoring wastes a lot of manpower and financial resources

Therefore, a method of pushing and updating the equipment data message on the monitoring screen of the converter station is proposed. It is necessary to identify the characters in the message to push the message. Considering that the equipment status data message on the monitoring screen of the converter station is not composed of some It is composed of random characters, but is composed of some specific characters. At present, the method of combining template matching and character structure features is used. Although the recognition speed is fast, the accuracy rate can only reach about 85%. The device data message It is extremely important for the operation and maintenance personnel of the converter station. If the information obtained is wrong, it is likely that the fault is not handled in time or the fault is handled incorrectly, which may cause an accident in the power system and cause great economic losses and safety problems. Therefore, the accuracy rate of 85% It is far from enough. In view of this, it is necessary to provide a method with high message push accuracy and improve push efficiency.
