Automatic transformer station unchanged telemeasuring data detection method and system

Abstract

The invention discloses an automatic transformer station unchanged telemeasuring data detection method and system and relates to the transformer station monitoring technology field. The method comprises steps that a dead zone value of a voltage of each transformer station is set, telemeasuring data generated by each transformer station is received and is displayed, the telemeasuring data generated before and after by one same transformer station is detected and compared, the comparison results are stored, when the comparison results of the telemeasuring data of the one same transformer station are continuously unchanged, the telemeasuring data of the transformer is determined to be the unchanged telemeasuring data, when the unchanged telemeasuring data satisfies the set condition, the alarm information is triggered, and a processing alarm signal is emitted. The method is advantaged in that the telemeasuring data of the transformer station can be monitored in real time, disqualified transformer station telemeasuring data can be timely detected and discovered, so timely processing on the disqualified transformer station telemeasuring data is facilitated, not only can a state estimation qualified rate index be improved, but also accuracy and timeliness of the telemeasuring data can be guaranteed, monitoring performance of a power grid can be improved, and safety and stable operation of the power grid is guaranteed.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a method and system for automatic detection of substation unchanged telemetry data. Background technique [0002] With the continuous development of my country's power system, the total amount of power system data has also maintained a high-speed growth trend. With the impact and increase of market competition, the complexity of management has been greatly increased. Applications provide the necessary conditions for proper development. Over the years, a number of opinions and suggestions have been put forward for the improvement of D5000 system functions, most of which have been adopted by the provincial company and submitted to the manufacturer for technical development. At present, some achievements have been put into practice or trial operation on site. The safe and stable economic operation of the power grid is bound to strengthen the scientific research and app...

AI Technical Summary

Problems solved by technology

Telemetry data is also a type of data in power grid monitoring data that is second only to the number of remote signals. It is inevitable that there will be some unqualified measurements in these huge data. 80% of the unqualified measurements have unqualified measurements, which will seriously affect the real-time monitoring of the power grid by dispatchers and monitors. Accurately and quickly discover and locate problems, which pose a great threat to the safe and stable operation of the power grid
