Substation computer monitoring system and method

Abstract

The invention provides a substation computer monitoring system and method. The system comprises a monitoring and control device, a man-machine interface configuration module, an automatic IED (Intelligent Electronic Device) model configuration module, an automatic version matching module, a protocol converter, an adaptive communication module of the protocol converter, and a background monitoring subsystem, wherein the monitoring and control device, the man-machine interface configuration module, the automatic IED model configuration module, the automatic version matching module, the protocol converter and the adaptive communication module of the protocol converter are connected with the background monitoring subsystem respectively. The system has the benefits that the substation configuration information can be set by a user according to the specific demand, and a corresponding background monitoring subsystem interface can be quickly displayed; IED performance description files and mapping files can be quickly generated according to different configurations, so that the manual workload is greatly reduced, the error probability is reduced, and the labor cost is reduced; existent hardware problems can be detected in advance and corresponding strategies can be found; the matching situation of the software versions of the background monitoring subsystem and the monitoring and control device can be mastered in time.

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 (IED capability 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 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
