Embodiment 1

[0050] Telemetry is remote measurement, which is a technology that transmits the short-distance measurement value at the substation level to the long-distance main station level to realize long-distance measurement. Telemetry data is generally divided into short floats and normalized values.

[0051] like figure 2 As shown, the telemetry ID is automatically generated, so it only needs to manually enter the point number, and the consistency with the factory station is guaranteed. If they are inconsistent, because of the uniqueness of the telemetry ID and point number, an alarm can be judged and generated through a software program, and manual intervention is required later. For telemetry data, the data transmission channel is divided into a dedicated line channel and a data network channel, so the error of data transmitted by different channels is required not to exceed 1%, and the data transmission time should not exceed 4s.

[0052] As can be seen from the above, the intel...

Embodiment 2

[0059] Remote signaling is the remote status signal, which transmits the status signal of the equipment at the substation level to the main station side remotely. The state of remote signaling generally uses binary numbers "0" and "1", which represent the state "point" (exit) and "close" (input). For the displacement remote signaling state, it is also required that the data transmitted by different channels maintain consistency and synchronization, and the data transmission time should not exceed 3s. Displacement remote signal data is divided into position signal and protection signal. The program can automatically classify and judge through time series, remote signal ID and remote signal point number, and meet different remote signal displacement conditions.

[0060] Among them, the present invention introduces an anti-interference mechanism in the process of acquiring the displacement remote signal state, because in the actual debugging process, other electrical tests may be...

Embodiment 3

[0070] Remote control is remote control, which is to issue commands from the master station side to realize the operation of remote equipment at the substation level. The remote control steps are generally divided into remote control preset, remote control execution, and remote control return to school. The remote control commands include "open" and "close", represented by binary "0" and "1" respectively. The remote control result is reflected by the remote signal state, so the anti-jamming mechanism is also introduced in the remote control process.

[0071] At the same time, the remote signaling meter and the digital control meter trigger whether the corresponding switch is remote controlled. In order to prevent false remote control caused by channel switching or configuration errors, an anti-interference mechanism is also introduced. There is a strong one-to-one correspondence between them.

[0072] like Figure 4 and Figure 5 Combined with what is shown, the results of...

Abstract

The invention discloses an intelligent checking and processing method based on mixed data of a power monitoring system. A data invoking relationship among all system applications of a power monitoringsystem is studied and data relationships between all system units and advanced applications are analyzed to form a data source relationship tree of the power monitoring system and a network securitymanagement system; and data collection information, including remote measuring, remote signaling, remote controlling and warning and the like, of the power monitoring system is analyzed to form a standardized process of data source changing. According to the invention, functions of automatic process realization, intelligent flow generation, active result determination, and abnormal real-time warning are realized during the automatic operation and maintenance and debugging process of the dispatching.

Description

technical field [0001] The invention relates to the technical field of automatic dispatching and debugging of a power monitoring system, in particular to an intelligent checking and processing method based on mixed data of a power monitoring system. Background technique [0002] The power monitoring system provides a basic platform for real-time data collection, switch status detection and remote control of dispatching automation. Its main functions include telemetry, remote signaling, remote control and communication. However, in actual work, scheduling automation debugging involves many systems and equipment, especially the importance of secondary security is becoming more and more prominent, and the access to the network security management system is essential. At the same time, the debugging work is cumbersome, and when a problem occurs, it cannot be quickly judged and located. Contents of the invention [0003] The purpose of the present invention is to provide an in...
