Background technology
IEC61850 standard is TC57 working group of International Electrotechnical Commission for " substation communication network and the system " series standard that solves the up-to-date appointment of interoperability new problem that electric substation automation system faces.This standard obtains the support of domestic and international most of main flow producer, become the whole world in automation of transformation substations field unique unified standard, therefore in the communication of on-line monitoring shelf depreciation intelligent electronic device, also obtain applying more and more widely.
Along with the promotion and application at intelligent substation based on IEC61850 standard primary equipment on-line monitoring, as the senior application of intelligence of intelligent substation important feature if the functions such as primary equipment health status assessment are also in pilot application progressively.Even but utilize actual on-line monitoring intelligent electronic device, and being also difficult to the fault of primary equipment to simulate, and being generally difficult to possess this condition in laboratory, this has caused very large difficulty for the problem of following the tracks of and find senior application.Another kind method is to use the emulation of general purpose I EC61850/MMS service end, manually generation remote measurement, remote signalling amount are simulated the communication behavior of on-line monitoring intelligent electronic device, but between each analog data that on-line monitoring intelligent electronic device sends, analog quantity and remote signalling amount data are especially inherent logical relations, this logical relation is simulated the key point of primary equipment fault just, and the emulation of general purpose I EC61850/MMS service end is difficult to meet corresponding requirement.Therefore how to carry out simply efficiently the simulation of on-line monitoring intelligent electronic device communication simulation, relevant senior application is developed to debugging, and on engineering test platform, verify it is a problem demanding prompt solution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of partial discharge monitoring devices communicating emulation mode based on IEC61850, the present invention can use ordinary PC to set up partial discharge monitoring intelligent electronic device analogue system, be used for replacing actual on-line monitoring intelligent electronic device etc., produce the online monitoring data of the malfunction of primary equipment, carry out convenient, flexible debugging and verification with senior application such as the primary equipment health status assessments to automatic system of intelligent transformer station.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A partial discharge monitoring devices communicating emulation mode based on IEC61850, comprises the steps:
Step (1): emulation starts IEC61850/MMS communication service;
Step (2): inquiry is stored in the value for the treatment of each analog quantity that emulation partial discharge monitoring intelligent electronic device once analyzes in SQL database in advance;
Step (3): use the out-of-limit generation alarm regulation of pre-configured remote measurement, automatically calculate corresponding alarm remote signalling state;
Step (4): send each analog quantity and alarm remote signalling state with IEC61850 report form;
Step (5): wait for lower secondary data delivery time, repeating step 2, until all pre-deposit datas are sent.
Described step (2) specifically refers to: use SQL database by markers row ranking and searching function, find out each analog data section of certain Analysis of Partial Discharge.
Described step (3) specifically refers to: the rule that uses the out-of-limit generation alarm of pre-configured remote measurement, the current analogue value of an autoscan remote measurement amount, with the pact of each remote measurement more the upper limit or upper higher limit compare, and alarm setting is carried out in the more upper limit remote signalling to correspondence or upper limit remote signalling according to comparative result.
Beneficial effect of the present invention is, can use ordinary PC to set up partial discharge monitoring intelligent electronic device analogue system, be used for replacing actual on-line monitoring intelligent electronic device etc., produce the online monitoring data of the malfunction of primary equipment, the complexity of debugging work before these senior application put into operation has been simplified in dependence to actual on-line monitoring intelligent electronic device when having broken away from intelligent substation primary equipment health status and the senior application debugging such as commenting simultaneously.
Brief description of the drawings
Fig. 1 is emulation mode schematic flow sheet of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, be a kind of partial discharge monitoring devices communicating emulation mode based on IEC61850, comprise the steps: step (1): emulation starts IEC61850/MMS communication service; Step (2): inquiry is stored in the value for the treatment of each analog quantity that emulation partial discharge monitoring intelligent electronic device once analyzes in SQL database in advance; Step (3): use the out-of-limit generation alarm regulation of pre-configured remote measurement, automatically calculate corresponding alarm remote signalling state; Step (4): send each analog quantity and alarm remote signalling state with IEC61850 report form; Step (5): wait for lower secondary data delivery time, repeating step 2, until all pre-deposit datas are sent.
Described step (2) specifically refers to: use SQL database by markers row ranking and searching function, find out each analog data section of certain Analysis of Partial Discharge.
Described step (3) specifically refers to: the rule that uses the out-of-limit generation alarm of pre-configured remote measurement, the current analogue value of an autoscan remote measurement amount, with the pact of each remote measurement more the upper limit or upper higher limit compare, and alarm setting is carried out in the more upper limit remote signalling to correspondence or upper limit remote signalling according to comparative result.
Between each analog data that on-line monitoring intelligent electronic device sends, analog quantity and remote signalling amount data are especially inherent logical relations, and this logical relation is simulated the key point of primary equipment fault just.When primary equipment fault, an analog quantity information can be stored in the database of supporting SQL, can use the in-process database of lightweight as SQLite for emulation, the information of each remote measurement amount need comprise the information such as section sequence number, logical device name, data object are quoted, remote measurement value.
Because IEC61850 standard specifies wherein CID(Configured intelligent electronic device Description) file including the complete model information of intelligent electronic device while putting into operation, emulation can be used the existing CID file of actual simulated equipment, resolve all information and the configuration that obtain this equipment correspondence with foreign country, start IEC61850/MMS communication service.
Re-use all distant measurement data of searching merit and be stored in a certain section in database of SQL database, then use the rule of the out-of-limit generation alarm of pre-configured remote measurement, the current analogue value of an autoscan remote measurement amount, more the upper limit or upper higher limit compare with the pact of each remote measurement, and according to comparative result, alarm setting is carried out in the more upper limit remote signalling to correspondence or upper limit remote signalling, sends each analog quantity and alarm remote signalling state with IEC61850 report form.
Then judge whether that all pre-deposit datas are all sent, if be sent, stop sending; If also have simulated data to be sent, enter wait flow process, the fault simulation data of preparing to carry out next time send.
