A substation ups power supply monitoring system and method

Abstract

The invention provides a system and method for monitoring a UPS of a transformer substation. The system comprises an intelligent device information collecting terminal, a human-machine interface configuration module, an IED module automatic configuration module, a version automatic matching module, a self-adaptive communication module and a background monitoring center. The intelligent device information collecting terminal, the human-machine interface configuration module, the IED module automatic configuration module, the version automatic matching module and the self-adaptive communication module are connected with the background monitoring center. The system and method for monitoring the UPS of the transformer substation have the advantages that a user can set configuration information of the transformer substation according to a specific requirement to quickly display an interface of a sub-system of the transformer substation; an IED performance description file and a mapping file can be quickly generated according to different configurations, manual workload is greatly reduced, the error probability is reduced, and labor cost is reduced; an existing hardware problem can be detected in advance, and a corresponding strategy can be found; the matching situation of a software version of an upper computer and a software version of a lower computer can be grasped in time.

Description

technical field [0001] The invention relates to the field of UPS power monitoring, in particular to a substation UPS 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 UPS power supply systems, the operating status of most UPS power supply equipment cannot be fully grasped. [0003] In a substation, the UPS power supply is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment, and is one of the important components to ensure the normal operation of the substation. At present, substations are developi...

AI Technical Summary

Problems solved by technology

[0005] 1. The human-machine interface of the existing UPS power supply monitoring device and the configuration, layout, and wiring of the substation are a strong coupling mode. Each substation needs to develop a set of human-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 UPS power supply equipment of the substation is modeled using the 61850 model file implemented by the IEC61850-7-420 standard. The IEC61850-7-420 standard does not list the relevant extension classes for the logical nodes of the UPS power supply equipment of the substation

Since the launch of the DL / T860 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 (logicalnode, 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 UPS power supply devices of different manufacturers, with the addition of system software requirements and the increase of measurement points, the software version of the UPS 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 UPS 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
