A substation computer monitoring system and method

Abstract

The invention provides a substation computer monitoring system and method, including: a measurement and control device, a man-machine interface configuration module, an IED model automatic configuration module, a version automatic matching module, a protocol converter and its self-adaptive communication module, and a background monitoring subsystem ; The measurement and control device, man-machine interface configuration module, IED model automatic configuration module, version automatic matching module, protocol converter and its adaptive communication module are respectively connected to the background monitoring subsystem. Beneficial effects of the present invention: users can set substation configuration information according to specific requirements, and quickly display the corresponding background monitoring subsystem interface; can quickly generate IED performance description files and mapping files according to different configurations, greatly reducing manual workload and reducing The error probability reduces labor costs; it can detect existing hardware problems in advance and find corresponding strategies; it can timely grasp the matching situation between the software version of the background monitoring subsystem and the software version of the measurement and control device.

Description

technical field [0001] The invention relates to the field of computer monitoring, in particular to a substation computer monitoring system and method. Background technique [0002] At present, the substation computer monitoring technology is very mature, and the function design is more and more comprehensive. However, the increase in requirements and functions has also brought about the complexity of the installation and debugging process and the doubled workload. As the power load increases and changes more and more frequently, the demand for substation automation to quickly complete commissioning and reliable operation is becoming stronger and stronger. There are still some deficiencies in the substation computer monitoring system in this regard. [0003] In the substation, the computer monitoring system completes the functions of collecting and displaying the operation data and status information of the electrical equipment in the substation, fault alarm, historical data...

AI Technical Summary

Problems solved by technology

Since the introduction of the DL / T860 standard, the original modeling method cannot meet the requirements of the existing standard, and it does not meet the bidding specifications of the State Grid, and the interoperability is poor

[0007] The 61850 model file has been completed by manual editing. Manual editing of the IED capability description (IEDcapability description, hereinafter referred to as ICD) file requires high technical requirements for engineers, and the workload is heavy and error-prone

[0008] 3. Due to reasons such as changes in the software version of the measurement and control device, the software version of the monitoring system may not match the software version of the measurement and control device, resulting in the failure of the monitoring system to operate normally, especially for smart substations and unattended power stations.

[0009] 4. At present, the communication mechanism between the substation computer monitoring system and the serial port intelligent electronic device (hereinafter referred to as IED) is to manually configure the port information first, then save the parameters and restart to take effect

This configuration modification-save-restart mechanism has high technical requirements for operators, and poor flexibility and compatibility
