Embodiment 1
[0046] A method for establishing a general test case framework system for relay protection is carried out through the following steps:
[0047] Step 1. Establish a fixed value list library;
[0048] Step 2. Establish basic operations;
[0049] Step 3: Establish a basic function library;
[0050] Step 4, comprehensively establish a product type template library;
[0051] Step 5: Generate actual test cases according to the characteristics of the target product, record data and make judgments on test objects.
[0052] Wherein, the first step is to exhaustively enumerate the corresponding maximum fixed value list for each type of protective device according to the design specification.
[0053] The template of the fixed value list is set with list library fixed value name, device fixed value name, minimum value, maximum value, median value, error 1, error 2 and unit.
[0054] The basic operation in step 2 is set to at least one single operation of applying current and voltage,...
Embodiment 2
[0077] A method for establishing a general test case framework system for relay protection, other features are the same as in Embodiment 1, the difference is that it also includes step 6, generating test cases identical to the actual test cases in step 5 for multiple devices of the same type , and record data and make judgments on test objects. Such as figure 1 shown.
[0078] Step 6 can be carried out in the following ways:
[0079] Multiple devices of the same type are tested according to the established product type template library, fixed value and error list, adopt the method of current series connection and voltage parallel connection, and output the same applied amount as the single test device to test multiple devices of the same type.
[0080] The method for establishing a general test case frame system for relay protection of the present invention is suitable for testing multiple devices of the same type, and can increase the test rate.
Embodiment 3
[0082] A method for establishing a general test case framework system for relay protection, such as figure 1 As shown, the setup has the following steps:
[0083] Step 1. Establish a fixed value list library;
[0084] Step 2. Establish basic operations;
[0085] Step 3: Establish a basic function library;
[0086] Step 4, comprehensively establish a product type template library;
[0087] Step 5: Generate actual test cases according to the characteristics of the target product, record data and make judgments on test objects.
[0088] Step 6: Generate test cases identical to the actual test cases in step 5 for multiple devices of the same type. Then you can start the test, record the data and judge the test object.
[0089] Each step is described in detail below.
[0090] Step 1. Create a fixed value list library
[0091] In order to facilitate the establishment of the basic function library, for each type of protection device, such as transformer, bus bar, line, bus tie...
