A substation intelligent auxiliary monitoring system and method

Abstract

The invention discloses an intelligent auxiliary monitoring system and method for a substation. The system comprises an adaptive communication module, an intelligent electronic device (IED) model automatic configuration module, a version automatic matching module and an XML based interface configuration module. The adaptive communication module is used for achieving adaptive communication between a comprehensive monitoring host and various sub-monitoring systems. The IED model automatic configuration module is used for generating IED performance description files rapidly after the system configuration is changed. The version automatic matching module is used for achieving automatic matching of an integrated power supply system and the comprehensive monitoring host software version. The XML based interface configuration module is used for enabling XML files to perform description modeling on the whole character lattice LCD human-computer interface to generate an interface according to the model files. By the aid of the system and the method, high multi-system fusion is performed on technologies of IED model automatic configuration, version automatic matching, adaptive communication, interface configuration and the like, and a uniform novel intelligent auxiliary monitoring system platform which is intelligent and efficient and adaptive to substation development requirements is built.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an intelligent auxiliary monitoring system and method for a substation. Background technique [0002] As the core link of the power system, the substation is responsible for the high and low voltage conversion and power supply tasks in the area. In order to ensure the reliable and stable operation of the substation, auxiliary monitoring systems such as video surveillance, power supply monitoring, environmental detection, security monitoring, intelligent lighting, and fire protection need to be deployed in the substation. At present, these systems are still independent and scattered small automation systems, which require many aspects of human labor to pay attention to, understand and maintain the information of these systems, which cannot meet the development needs of smart substations. [0003] Specifically, there are the following technical problems: [0004] 1. The existing auxiliary m...

Problems solved by technology

This solution is not suitable when the interface requirements are frequently modified

In addition, this kind of code has poor reusability. When we use a unified platform to develop programs with different functions, the code reuse rate is too low

[0006] 3. The existing intelligent electronic device (hereinafter referred to as IED) model cannot complete automatic configuration: the 61850 model file has been completed by manual editing, and manual editing of the IED capability description (IED capability description, hereinafter referred to as ICD) file is not Engineering personnel have high technical requirements, heavy workload, and error-prone

[0007] 4. Substation power consumption includes AC power monitoring, DC power monitoring, station AC uninterruptible power supply monitoring, communication power monitoring, etc. Due to the disconnection in technical coordination of power supply devices of different manufacturers, many problems were encountered during operation and debugging. The addition of system software requirements and the increase of measurement points may cause a mismatch between the software version of the integrated power system and the software version of the DC, AC and other power systems, and the equipment cannot operate normally.

[0008] 5. The existing substation auxiliary monitoring system can only view the video and environmental signals separately. When the environmental signal triggers the linkage of video monitoring, the so-called linkage here is the process in which the fault signal triggers another action (such as the rotation of the camera) , if the monitoring screen is displaying other content or performing other operations, because it is not in the same screen, it is impossible to check the scene monitored by the linked camera in time, and it is necessary to manually search for the currently linked camera

This creates unnecessary troubles and affects the real-time and accuracy of checking faults
