Description

Based on the distribution transformer status monitoring information acquisition and processing system of IEC61850 standard

Technical field

The utility model belongs to electric power monitoring technical field, is specifically related to a kind of distribution transformer status monitoring information acquisition and processing system based on IEC61850 standard.

Background technology

The remote transformer in current many positions due to Surveillance center apart from too far away, Surveillance center abandons the status real time monitor to transformer, take the method that human at periodic intervals patrols and examines and record is carried out to the duty of transformer, but regular visit is discretize in time, cannot the duty of grasp transformer of real-time continuous, also cannot process timely some faults, this just causes potential threat to electrical network to a certain extent.

IEC61850 is the new standard that International Electrotechnical Commission TC57 formulates, and is the unique international standard of electric substation automation system, when smart machine meets the standard of IEC61850, can better communicates, realize interoperability between each equipment.

Utility model content

For the defect that prior art exists, the utility model provides a kind of distribution transformer status monitoring information acquisition and processing system based on IEC61850 standard, this system realizes realizing independently information acquisition and process to the transformer of by-place, can eliminate timely some faults.

The remote transformer in current many positions due to Surveillance center apart from too far away, Surveillance center abandons the status real time monitor to transformer, but the serviceable life of transformer not only can be extended to the Real-Time Monitoring of transformer state, and some faults can also be processed timely, improve electricity consumption reliability.Therefore, the status monitoring of transformer is necessary, smart machine IED(Intelligent Electronic Device by by each monitoring of this system), the diverse location of transformer is installed to according to Contents for Monitoring, just can realize the status monitoring to transformer, do not need again with PERCOM peripheral communication.

The technical scheme that the utility model adopts is as follows.

This system comprises oil chromatography monitoring IED, micro-water monitoring IED, monitoring IED is put in office, iron core monitoring IED, casing monitoring IED, isolation module, communication module, power module, central processing module, display module, memory module, described central processing module monitors IED by isolation module and oil chromatography, micro-water monitoring IED, monitoring IED is put in office, iron core monitoring IED, casing monitoring IED is connected, and central processing module monitors IED to oil chromatography, micro-water monitoring IED, monitoring IED is put in office, iron core monitoring IED, the monitoring information process that casing monitoring IED collects also feeds back to their process informations, when the equipment running status monitored exceed warning value time, central processing module can feed back to corresponding IED warning tripping operation information, described oil chromatography monitoring IED monitors Gases Dissolved in Transformer Oil, the insulativity of transformer is obtained by the micro-characteristic gas contained in comparative analysis oil, described micro-water IED monitors content of micro water in transformer oil, monitoring IED is put to Partial Discharge Online Monitoring of Transformers in described office, described iron core monitoring IED is to the monitoring of iron core grounding current, described casing monitoring IED is to bushing shell for transformer insulativity on-line monitoring, described isolation module plays the effect of protection central processing module by light-coupled isolation, described display module display oil chromatography monitoring IED, micro-water monitoring IED, monitoring IED is put in office, iron core monitoring IED, casing monitoring IED uploads to the data of central processing module, and described memory module can store oil chromatography monitoring IED, micro-water monitoring IED, monitoring IED is put in office, iron core monitoring IED, the information that casing monitoring IED collects, smart machine IED(Intelligent Electronic Device by by each monitoring of this system), be installed to the diverse location of transformer according to Contents for Monitoring, just can realize the status monitoring to transformer, do not need again with PERCOM peripheral communication.

the beneficial effects of the utility model are: by the use of this system, realize the status monitoring to transformer and record, and the fault handling of some necessity, without the need to communicating with national grid Surveillance center, native system achieves the function of the storage of information in-site collecting and fault treatment in situ again.Improve electricity consumption reliability to a certain extent, extend the serviceable life of transformer.
