Embodiment
See also Fig. 1, Fig. 1 is the schematic flow sheet of power equipment iknsulating liquid on-line monitoring method of the present invention.
Said power equipment iknsulating liquid on-line monitoring method may further comprise the steps:
S101 is kept at the iknsulating liquid Monitoring Data model of setting up in advance in the SCD file of IEC61850, is sent to monitoring center;
Said iknsulating liquid Monitoring Data model comprises: the data model of the monitoring logic node corresponding with said on-Line Monitor Device, and the data model of each data object of said on-Line Monitor Device monitoring.
Wherein, a Monitoring Data model can comprise a plurality of said monitoring logic nodes, all corresponding monitoring logic node of each on-Line Monitor Device; The data of the different measured object of same IED (intelligent electronic device, Intelligent Electronic Device) are answered newly-built monitoring logic node, for example comprise the out of phase monitoring of switch.The data model of said monitoring logic node mainly defines the title of said logic node, attribute etc.Because the present invention is primarily aimed at liquid medium insulation SIML, therefore, said logic node name can unify to adopt SIML.
The data model of said data object comprises: the pattern of said on-Line Monitor Device, performance, health status and nameplate information; The semaphore of said data object or quantity of state, measured value and setting value; And the data name of said data object, CDC are described, unit.
In this step, said unified iknsulating liquid Monitoring Data model is kept in the SCD file of IEC61850, the SCD model file that generates the compliant requirement is to deliver to remote monitoring center on the MMS mode.
After S102, monitoring center receive said SCD file, resolve said SCD file, generate substation model according to said iknsulating liquid Monitoring Data model.
S103 obtains the Monitoring Data of each on-Line Monitor Device to the power equipment iknsulating liquid, and said online monitoring data is sent to monitoring center through the IEC61850 stipulations;
On-Line Monitor Device is gathered Monitoring Data; Use IEC61850 stipulations and overall treatment unit (or on-line monitoring server) to carry out communication; Monitoring Data is followed " DL/T 860 technical application standards " by on-Line Monitor Device and is generated the ICD model file of compliant requirement and to send the overall treatment unit on the MMS mode, carry out data transmission by the same IEC61850 stipulations that adopt between overall treatment unit (or on-line monitoring server) and the remote monitoring center main website.
Each on-Line Monitor Device mainly is the monitoring transformer insulation oil to the on-line monitoring of power equipment iknsulating liquid; Transformer through long-time running because the local overheating that a variety of causes produces and repeatedly cut-off the electric arc of formation; And the deterioration of other structured materials, will certainly make the aging and a spot of low molecular hydrocarbon class gas of decomposition generation of insulating oil and solid insulating material.Therefore, the on-line monitoring of transformer insulation oil mainly is again to detect oil dissolved gas.Dissolved gas analysis (DGA) has been listed in the first place of DL/T596-1996 " power equipment preventive trial rules " transformer test project as the main pilot project of the inner latency fault of monitoring transformer.
Oil dissolved gas on-line monitoring and fault diagnosis mainly are all gases component content, for example hydrogen, carbon monoxide, methane, ethene, acetylene and ethane etc. in the monitoring transformer.The project that different manufacturers and distinct device are monitored is different, but mainly all is the concentration data of monitoring gas componant, and when concentration surpasses certain alarm threshold value, sends corresponding concentration and report to the police.
Outside the dissolved gas Monitoring Data, the Monitoring Data of power equipment iknsulating liquid also has such as Monitoring Data such as oil temperature, micro-water contents in the oil removing.
S104, monitoring center replenish the data content of said substation model according to said online monitoring data.
According to said iknsulating liquid Monitoring Data model; Import the Monitoring Data and the Monitoring Data such as oil temperature, micro-water content of the above-mentioned oil dissolved gas that obtains; Data layout rule according to said iknsulating liquid Monitoring Data model generates complete substation model file.The title that has unified logic node in the then said substation model file, attribute; And pattern, performance, health status and nameplate information to the on-Line Monitor Device in the said logic node; The semaphore of said data object or quantity of state, measuring amount and setting value; And the data name of said data object, CDC are described, unit all from following said iknsulating liquid Monitoring Data model, has uniform data format.
Compared with prior art; The present invention is through being kept at unified iknsulating liquid Monitoring Data model in the SCD file of IEC61850; Be sent to monitoring center; Resolve said SCD file and generate substation model, and online monitoring data is also started to monitoring center, accomplish complete unified substation model file.Therefore; Can be through the present invention with online monitoring data by different manufacturers, distinct device disposed; All be made into unified monitoring model file; The iknsulating liquid Monitoring Data model that said monitoring center receives meets unified standard, does not therefore need respectively the online monitoring data that different manufacturers, distinct device disposed to be discerned or data conversion treatment.For the data basis of realizing that status of electric power evaluation is accurately provided convenience easy-to-use, improve the stability and the reliability of operation of power networks.
As a kind of preferred implementation, in step S102, when said monitoring center generates substation model, the distribution of the power equipment in said substation model corresponding equipment is encoded according to the device code of said on-Line Monitor Device.
