Protective relaying device modularization automatic test suite system and method for testing
Technical field
The present invention relates to a kind of Microcomputer Protection on-site test system and method for testing, especially a kind of protective relaying device modularization automatic test suite system and method for testing.
Background technology
It is extremely important in substation equipment maintenance and repair two tasks that protective relaying device is examined surely, equally also is one of very frequent work; Because the Interventions Requested of protective device are many, workload is big, and is very high with the requirement of work proficiency to tester's level professional technology.At present, the relay protection field test of electric system constituent parts mainly is to adopt the desk checking method, and the weak point outstanding behaviours of existence exists:
When 1, tradition is carried out the scene protection detection; Utilize relay-protection tester; Often need carry out manual testing item by item to the various defencive functions that protective relaying device comprised; Rely on that the on-the-spot test personnel are subjective to differentiate whether qualified and hand-kept test result of test result, the job instruction of field-checking work is carried out also difficulty and is fulfilled.Sometimes even because of tester's subjective judgement make mistakes and record is made mistakes, cause unnecessary loss.Protect at the scene when detecting, often face that the test job amount is big, the tester to the scene protection test be unfamiliar with, artificial cognition is wrong, the problem that test report can not in time be filled in.
2, along with the expansion of scale of power, transformer station newly throws and the capacity expansion project project is on the increase, and protective device is variation day by day, and the old and new's protective relaying device is also deposited.Simultaneously, because of the supply power social demand of continuation of mains supply reliability and user, relay protection work is faced with the problem that maintenance, test duration are shortened day by day.
3, protection professional ubiquity lazy weight, the uneven problem of quality of constituent parts are difficult to guarantee the quality of work for inspection.In the duration tight, when pressure is big, increased the possibility of false retrieval, omission.
4, test report also needs manual sorting; Taken tester's valuable time, can not in time generate test report, the test data of different times can't in time be provided or compare same protective relaying device; Paperyization is adopted in the management of test report, does not meet the mode of modern management.
5, in order to ensure the quality and the safety of work for inspection, state net company requires to carry out the standardized work mode, but lacks a kind of practicable manner of execution at present.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art, a kind of protective relaying device modularization automatic test suite system and method for testing are provided.It has reasonable in design, and is with strong points, economy and social benefit advantage such as produce effects obviously.
To achieve these goals, the present invention adopts following technical scheme:
The automatic test suite of a kind of protective relaying device modularization system, it comprises three-layer architecture, said three-layer architecture is respectively contact bed, logical layer, data Layer;
Said contact bed comprises plan formulation module, planning execution monitoring module, test report processing module; Common platform module, contact bed are used to accomplish fixed value adjusting experiment, real time data processing, interface display and information check and analytical work;
Said logical layer comprises relay-protection tester control module assembly, data access module, protection verification rules parsing module; Logical layer is used to accomplish relay-protection tester control, data access, protection inspection procedure analytical capabilities; The nucleus module that has comprised all native systems in the logical layer; Each module all is by object-oriented ideology its function to be encapsulated; Operation by the contact bed on upper strata is called; Its result returns to the test result display field that the contact bed median surface shows, and deposits in simultaneously in the database and call and inquire about in order to the later stage;
Said data Layer, data Layer are used to accomplish the management work of data and data are provided for logical layer and contact bed;
Said data Layer comprises database, is provided with the test template and the report template of protective relaying device in the said database, and test template is to set up respectively for the repertoire of the different protective relaying devices of statement different manufacturers; Comprise test report in the said report template; The filling-in position of said test report test result is the User Defined pattern, and through test template, system further obtains the assessment of protective relaying device performance; Behind EOT, generate the test report that the user makes form by oneself at once automatically; System accomplishes the incorporate function of protective relaying device test and evaluation;
Module is formulated in said plan: this module functions is based on relay protection check job instruction; Set up test template to the intelligent protection equipment of concrete model; Fixed value list with concrete protection equipment to be detected is the basis; Therefrom extract concrete protection definite value, select concrete waiting to do the fixed value adjusting test, generate a whole set of verification test plan that is applied to this concrete equipment at last according to the protection verification rules parsing module in the logical layer.
Said planning execution monitoring module: when testing at the scene; The user is through the implementation status of this module real time inspection plan; The user comes time-out, preservation, continuation, the retouching operation of control plan through the relay-protection tester control module; And, get access to Trouble Report, the analog quantity information of protection in real time through interface display.
Said test report processing module: behind the EOT; The user checks the raw readings of generation; And according to report template generation test record report; In this module, the user also browses, analyzes the test data of in the past at every turn on same equipment, carrying out, and checks and analysis operation with this result.
Said relay-protection tester control module assembly: the mode that native system adopts is to use the output of control module assembly control relay-protection tester; And relay-protection tester itself carries corresponding function and resolves and export each functional module that defines in this control module assembly, after output finishes, returns the switching value upset information of protection action at last.
Said data access module: be mainly used in and deposit test result information, report information data in database, and when analysis report, extract the report operation from lane database.
Said protection verification rules parsing module: this module is an important module relevant with test plan; Its effect is to carry out association to the inspection procedure of the pairing Utilities Electric Co. of equipment of each concrete model; According to the fixed value list of the defined formula of rules with concrete equipment; Generate the test plan of each test usefulness; This module is a flexible extendible module, and from now on according to the increase of unit type and the variation of rules, the user comes to expand voluntarily the function that rules are resolved through the mode of revising configuration file.
The method of testing of the automatic test suite of protective relaying device modularization system, the step that it comprises is:
1) terminal loading tasks packet is carried out on-the-spot automatic test; Utilize with relay-protection tester and set up communication,, utilize test template based on concrete model protective device to be tested according to inspection procedure and job instruction; In conjunction with importing fixed value list; Through comparing with it, judge, realize protective relaying device standardized work and automatic test;
2) utilize test report processing module and database to realize the management of protective relaying device status information, and assess automatically;
3) according to assessment result protective relaying device test mode, appreciation information are imported database automatically; Automatically generate test report.
