Description
Technical field
It is especially a kind of based on mms remote control and regulation protective device the present invention relates to power system automation technology field
Test method.
Background technique
At this stage, intelligent substation is tested encountering common problem encountered is that system under test (SUT) often changes, and many enterprises carry out intelligence
Energy substation test implementation is finally died without known cause, because being designed from the notice that system business changes is received to modification test to last
Online test, the time for leaving tester for is often very short, and corresponding test implementation development cost is high, can not be in the stipulated time
Interior timely completion.In view of the above-mentioned problems, being adopted during intelligent substation Test data generation, function control, Comparative result
The test method designed with full-automatic test script.
Summary of the invention
In view of this, the purpose of the present invention is to propose to a kind of test method based on mms remote control and regulation protective device, it can
Solve at this stage in intelligent substation test implementation to the design contents such as test parameter, configuration, scheme modify it is complicated, at high cost,
The problems such as low efficiency.
The present invention is realized using following scheme: a kind of test method based on mms remote control and regulation protective device specifically includes
Following steps:
Step S1: load test case；
Step S2: customized test parameter script is generated；Pass through the test of test function in the test cases of protective device
The test parameter of needs is converted to the location paths in the corresponding ICD file of protective device by parameter, and editor's location paths are formed
Script；When test, system automatically extracts the parameter position routing information in script, and it is fixed to read corresponding protection automatically by mms
Value, automatic switching protect pressing plate, automatic read action message；
Step S3: by configuring IP address, mask and port numbers in MMS information, the DIB_ in the library MMSLite is loaded
ENTRY structure filling by DIB_ENTRY connection protective device and creates MVL_VMD_CTRL, raw according to MVL_VMD_CTRL
It at MVL_NET_INFO, is obtained by the distal end MVL_NET_INFO and protects internal ICD model, and filled out according to the information acquired
VMD structure is write, completes to be communicated based on mobile agent server protocol with protective device；
Step S4: generate test data: the test parameter and protection definite value of system testing protective device function are associated, lead to
It crosses test parameter script and mobile agent server protocol is combined to connect protective device, obtain the information model of protective device, protected to read automatically
Protection unit definite value, and test parameter is converted by protection definite value, and keep these test parameters and value；
Step S5: start automatic test: sending SV and GOOSE message to protective device, tester is dynamic by receiving protection
Make feedback message, and message is reported into platform；
Step S6: platform obtains the result message reported, analyze and assess automatically to message, judges protection dress
Set tripping, coincidence, it is rear accelerate whether to act, judge whether action error meets the requirements, whether actuation time is in allowed band, dynamic
Whether correct make logic, result is provided after assessment.
Further, the step S1 specifically: connecting test system database, load test case library, if test case
Test cases in need in example library, is loaded directly into importing；If function is incomplete in case, load test function library, addition is needed
The test function wanted, on the contrary delete unwanted function；If the test cases that user needs is not present in system testing case library,
It then loads and generates new test cases.
Further, the load generate new test cases specifically includes the following steps:
Step S11: opening testing system software platform, load test function library, and selection needs defencive function item to be tested,
Import the test item that the defencive function item is formed in new case.
Further, further includes:
Step S7: test report is automatically generated: the report template that system is provided according to user, the number of binding test result
According to automatically generating test report；
Step S8: test result is saved.
Further, the present invention uses following technical scheme;
MMS information control: system provide MMS information configuration wicket, can with IP address, port numbers, TSEL, PSEL,
The information such as SSEL.Tester can extract the MMS connection of corresponding intrument in the case where holding SCD file from SCD file
Information can connect equipment under test after completing these information configurations.
Establish protection test cases: host computer use pc machine, realize protection test macro foundation, testing scheme establishment and
Load, test process monitoring, test result evaluation and generation report etc..System reads protective device by ICD file by mms
Facility information, parameter information, definite value etc., automatically generate test cases corresponding with producer and be saved in database.Tester
Member can load corresponding test cases as needed, can dynamically modify test parameter and form new case.
Defencive function Test data generation: the test parameter and protection definite value of system testing protective device function are associated,
Protective device is connected by mobile agent server protocol, obtains the information model of protective device, so that automatic reading protective device definite value is completed,
And definite value will be protected to be converted into test parameter by mathematical formulae and logical operation, and keep these test parameters and value.
Customized test parameter script: by the test parameter in the testing scheme of defencive function, the survey that these are needed
Examination parameter is converted to protective device and correspond to location paths in ICD file, edits these parameter paths formation script.When test,
System can automatically extract the parameter position information in script, read corresponding protection definite value, automatic switching protection automatically by mms
Pressing plate, automatic read action message.
Interpretation of result, assessment: assessed automatically test result, the criterion of assessment includes: tripping is overlapped, rear acceleration
Whether act, whether action error meets the requirements, whether actuation time correct in allowed band, action logic, after assessment
Provide result.Identify that equipment, equipment connect protective device according to the demand of test function, system sends test life to test equipment
It enabling, test equipment executes order and sends SMV or GOOSE to protective device, and it receives test result and uploads to PC system end, according to
It sends signal and received result message carries out analysis verifying and obtains a result and record preservation.
During protective device test implementation, core is exactly required test ginseng in the testing scheme according to test function
Test parameter is converted to the parameter position information inside protective device in ICD file, edits these information preservation file shapes by number
At script, when test, reads these information, and connects protective device based on the library MMSListe, is read and is protected according to parameter position information
Definite value inside protection unit, fills in the parameter value in testing scheme completely automatically, when starting test, send the SV of response with
GOOSE message to protective device, join protection action connection point and movement message assesses test result automatically, after the completion of test, from
The dynamic test report for forming User Format.
Compared with prior art, the invention has the following beneficial effects: the present invention passes through mobile agent server protocol library and combines customized foot
This connection protective device reaches dynamic and changes test data, test function, automatic test, analysis result and the side for generating report
Method.The invention avoids because test process malfunction or configure test data mistake when need to remodify entire testing scheme,
As long as redefining script, it can be retested using mms agreement connection protective device, is convenient and efficient.
