A substation integrated power monitoring system and method

Abstract

The invention discloses an integrated transformer substation power supply monitoring system and method. The system comprises an integrated power supply management system. The integrated power supply management system comprises an automatic version matching module, an adaptive communication module and a dynamic state configuration module. The automatic version matching module is used for monitoring software versions of the integrated management system and software versions of all monitoring units in real time. The adaptive communication module is in communication with external environment through interfaces and is used for automatically recognizing lower computers and completing automatic recognition on configuration files. The dynamic state configuration module is used for dynamically displaying a wiring graph and operation information of each monitoring unit. According to the integrated transformer substation power supply monitoring system and method, full-station alternating current, direct current, a UPS and communication are integrally configured and integrally monitored, station power supply sub-system communication is networked, so management is easier; interface protocols for the upper layer are abundant, variety selections of communication hardware interfaces for the lower layer are rich, and extendibility is high.

Description

technical field [0001] The invention relates to a substation integrated power supply monitoring system and method. Background technique [0002] The substation power system includes AC power monitoring system, DC power monitoring system, AC uninterruptible power supply monitoring system for electric power, communication power monitoring system, etc. The existing integrated power monitoring system has the following disadvantages: [0003] (1) Each power supply monitoring device may be produced and installed by different suppliers, and professionals at different levels are also assigned to maintain it in management; because the overall design ideas of power supply devices of different manufacturers are inconsistent, there are technical disconnects and incoordination. Encountered many problems during operation and debugging, sometimes even affecting the normal operation of the equipment, especially for smart substations and unattended power stations, the impact is greater; [...

AI Technical Summary

Problems solved by technology

[0003] (1) Each power supply monitoring device may be produced and installed by different suppliers, and professionals at different levels are also assigned to maintain it in management; because the overall design ideas of power supply devices of different manufacturers are inconsistent, there are technical disconnects and incoordination. Encountered many problems during operation and debugging, sometimes even affecting the normal operation of the equipment, especially for smart substations and unattended power stations, the impact is greater;

[0004] (2) Due to the addition of system software requirements and the increase of measurement points, the software version of the integrated power system may not match the software version of the DC, AC and other power systems, resulting in interconnection barriers, and in severe cases, the equipment cannot operate normally ;

[0005] (3) If the lower computer needs to re-modify the configuration to replace other types of equipment, 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;

[0006] (4) The human-machine interface of the existing integrated 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 human-machine interface separately, which cannot be flexibly displayed according to the requirements of the substation The human-machine interface information of each substation has poor software portability, resulting in heavy workload and difficult maintenance;

[0007] (5) Inconvenient operation of the man-machine interface, poor user experience and poor adaptability;
