The intelligent device information collecting terminal, the human-computer interface configuration module, the automatic IED model configuration module, the automatic version matching module and the self-adaption communication module are connected with the background monitoring center. The transformer substation communication power supply monitoring system and method have the advantages that a user can set transformer substation configuration information according to specific demands, and a corresponding transformer substation subsystem interface can be rapidly displayed; IED performance depiction files and mapping files can be rapidly generated according to configuration differences, manual workloads can be greatly reduced, the error probability is lowered, and the labor cost is reduced; hardware problems can be detected in advance, and corresponding strategies can be found in advance as well; the matching conditions of the software version of the upper computer and the software version of the lower computer can be grasped in time.

Description

technical field [0001] The invention relates to the field of communication power monitoring, in particular to a substation communication power monitoring system and method. Background technique [0002] At present, power grid dispatching automation is very mature and perfect, and more and more substations are unattended. However, after the evacuation of personnel, the safe operation of the substation has become extremely important, and the demand for safety monitoring has become stronger and stronger. Although the power grid dispatching automation system covers the information of some communication power systems, the operating status of most communication equipment cannot be fully grasped. [0003] In the substation, the communication power supply is responsible for providing power to the communication loads such as dispatching switches, communication distribution frames, and power carrier machines in the substation, and is one of the important components to ensure the norm...

AI Technical Summary

Problems solved by technology

[0005] 1. The man-machine interface of the existing communication power monitoring device and the configuration, layout, and wiring of the substation are a strong coupling mode. Each substation needs to develop a set of man-machine interface separately, and each substation cannot be flexibly displayed according to the requirements of the substation. The man-machine interface information, software portability is poor, not conducive to centralized control and digital communication, can not effectively realize man-machine dialogue, can not change the operating parameters arbitrarily during operation

[0006] 2. At present, the substation communication power supply equipment is modeled using the 61850 model file implemented by the IEC 61850-7-420 standard. The IEC61850-7-420 standard does not list the relevant extension classes for the logical nodes of the substation communication power supply equipment

Since the introduction of the DL / T 860 standard, the original modeling method cannot meet the requirements of the existing standard and does not meet the bidding specifications of the State Grid

The original model file has poor interoperability because different manufacturers create different logical nodes LN (logical node, hereinafter referred to as LN).

[0007] The 61850 model file has been completed by manual editing. Manual editing of the IED Capability Description (ICD) file requires high technical requirements for engineers, and the workload is heavy and error-prone

[0008] 3. Due to the technical disconnection and incoordination of the communication power supply devices of different manufacturers, with the addition of system software requirements and the increase of measurement points, the software version of the communication power supply system may not match the software version of other power supply systems. The equipment cannot operate normally, especially for smart substations and unattended power stations, which will have a greater impact

[0009] 4. The current communication mechanism of communication power supply equipment is to manually configure the port information manually, and 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
