The whole text of the present application is incorporated by reference in the present application.
The present disclosure relates to a distributed test method applicable to a system-level test of intelligent high voltage equipment, and belongs to the technical field of intelligent substation systems.
Intelligence of high voltage equipment is one of important items about intelligent power grid construction, and entire-life-cycle management of the high voltage equipment and optimized running of the power grid are achieved by means of functions such as state sensing, risk assessment, intelligent control and optimized regulation of the high voltage equipment. In order to ensure reliable running of intelligent high voltage equipment, it is necessary to carry out various tests on basic functions, performance indexes and the like at the stage of product design, delivery inspection or field installation. Because a system-level test of the intelligent high voltage equipment covers a plurality of pieces of equipment including a sensor layer, a spacer layer and a station control layer and integral function of the above pieces of equipment based on network interaction and mutual cooperation, this test is complex, and highly requires relevant work conditions and time sequences. At present, in actual engineering, due to limits of field conditions, only a single equipment-level test is carried out, continuous work condition simulation required by the system-level test is accomplished by manual cooperation, and system performances are manually evaluated. Therefore, the problems of high requirement on staffs, high time consumption, test incompleteness, low test efficiency and the like have been exposed.
The present disclosure aims to provide a distributed test method applicable to a system-level test of intelligent high voltage equipment, to solve the problems of difficult operation and low efficiency during debugging test of intelligent high voltage equipment at present.
To solve the above technical problem, the present disclosure provides a distributed test method applicable to a system-level test of intelligent high voltage equipment. The test method includes the following steps:
1) carrying out unified modeling on test equipment behaviors according to test requirements, and generating a general test case;
2) extracting basic elements associated with sequence states of same roles in the general test case, and recombining the basic elements according to an execution sequence so as to form test sub-cases of the roles;
3) executing, by each piece of test equipment, corresponding test sub-cases after a test is started, and achieving cooperative linkage by means of information interaction, so as to accomplish an entire process of test conditions.
The general test case in Step 1) globally carries out systematic description and normalized expression on behaviors and time sequences required by system work conditions, corresponding action subjects being determined in different processes of the general test case.
The unified modeling refers to systematically ensuring accuracy and coordination of test behaviors and test time sequences under various work conditions, and the basic elements contained in an established model include state time sequences, test work conditions, equipment behavior associations, sequence conversion modes and role definitions.
The roles refer to the action subjects in different processes of the general test case, namely the test equipment.
When each piece of test equipment executes the corresponding test sub-cases, an analog quantity or a switch quantity is correspondingly output according to a pre-set time sequence so as to achieve simulation of high voltage equipment work conditions and test equipment environments.
When each piece of test equipment executes the corresponding test sub-cases, output information about tested equipment and interaction information about other testers are collected in real time, and execution of the next work condition or skipping of relevant work conditions in a test sequence is carried out according to the interaction information.
The test method further includes: collecting, analyzing and evaluating, by each piece of test equipment, action feedback and data information in a test process, so as to automatically accomplish function verification and performance detection of the tested equipment.
The present disclosure has the beneficial effects as follows. In the present disclosure, firstly, unified modeling is carried out on test equipment behaviors according to test requirements, and a general test case is generated for ensuring accuracy and coordination of test behaviors and test time sequences under various work conditions; then, according to a characteristic element of role definition, for each of same roles in the general test case, sequence states of the same role are extracted from the general test case, and are recombined according to an execution sequence so as to form test sub-case of the role; finally, each piece of test equipment executes corresponding test sub-case to achieve cooperative linkage by means of information interaction, so as to accomplish entire process simulation of the test conditions. The present disclosure is simple to achieve and reliable, can automatically meet system-level test requirements of intelligent high voltage equipment, is good in openness, and can improve the efficiency and accuracy of a complex system-level test; meantime, representative test cases established in the above process can be solidified, such that the reusability and the flexibility are improved, and a popularization and application prospect is wide.
The specific implementation of the present disclosure will be further illustrated below in conjunction with the drawings.

Each piece of test equipment corresponds to a role, so test sub-case (as shown in
