Description
Technical field
The present invention relates to a kind of power grid protocol analysis and method of testing, belong to technical field of power systems.
Background technology
IEC60870-5-101 (2.0 editions, 2002) and IEC60870-5-104 (1.0 editions, 2000) agreement have been used widely in China since issue.China's power industry has been issued DL634.5101-2002 and DL634.5104-2002 agreement again, and indicates and to be and IEC60870-5-101 (2.0 editions, 2002) and IEC60870-5-104 (1.0 editions, 2000) are adopting by equation.Since this agreement contained remote measurement, remote signalling, remote control, remote regulating, to the time, telemechanical task substantially such as dress, file transfer under the parameter, and the transmission controlling mechanism of IEC60870-5-101/104 is perfect, makes that its range of application is very extensive.It is more that agreement offers user's option, but use personnel for electric power system, and configurable parameter is too many, is difficult for holding the apolegamy of parameter and the selection of application function on the contrary.
According to result for retrieval, finding does not domesticly still have complete protocol analysis, stipulations testing software, and domestic existing similar software is faced with the problem of three aspects: 1, do not have complete comprehensive stipulations test event, the stipulations test event is not configurable; 2, the weight of stipulations test event can not be self-defined, can not test automatically, needs the tester manually to intervene; 3, can only test correct reaction, can not analog communication in various mistakes.
Summary of the invention
Technical problem to be solved by this invention is:
1. further strengthened the consistency of each automation producer and each dispatching terminal signal procedure;
2. reduce the operating time of automation factory station end and main website end debugging;
3. avoid because the telemechanical stipulations defective that artificial origin or misinterpretation produce is beneficial to the management of automated communication program software.
For solving the problems of the technologies described above, the invention provides a kind of power grid protocol analysis and method of testing, it is characterized in that comprising the following steps:
1) list the power grid protocol test items: list all test points that contain stipulations, and all possible errors of analog communication process, according to predefined basis for estimation, judge the result of test individual event automatically;
2) power grid protocol test items weight is set: the heavy method of testing of the right to use, promptly each test event all is provided with weight, comprise and to survey and non-ly must survey item, must survey and have right of veto by one vote, if there is one must survey and do not pass through, whole stipulations test result is not just passed through, the non-item of must surveying can be provided with 1-5 level weight according to important level, calculate the total points of stipulations test at last, can draw the conclusion of stipulations test accurate science, have great practical value by the weight method of testing.
3) the automatic test event of power grid protocol test is set: the tester sets the parameter of automatic test, comprises period that period, mode of operation, the period of remote regulating, remote regulating value, the quality of remote control are described etc., and all test processs are controlled automatically;
4) stipulations are tested;
5) in test process, carry out record, and carry out complete monitoring: whole process is the test process of monitoring stipulations in real time, to the analysis that makes an explanation of stipulations message, mistake to current simulation is pointed out, correct response and wrong message are analyzed and pointed out, and test case and the result to each test event monitors in real time, and recorded message, but the message of inverting is simultaneously recurred test process.
6) obtain test result automatically, automatically printing test is reported list: behind the EOT, automatically draw test result and test detail, comprise each test event weight, whether test, pass through situation, form complete test report, and with the test case warehousing, so that inquiry test record in the past, comprise result, test detail, test process and test packet, and can look back test process.
The beneficial effect that the present invention reached:
Power grid protocol analysis of the present invention, stipulations method of testing by above step, have further been strengthened the consistency of each automation producer and each dispatching terminal signal procedure; Reduce the operating time of automation factory station end and main website end debugging; Avoided because the telemechanical stipulations defective that artificial origin or misinterpretation produce is beneficial to the management of automated communication program software.
