Description

Technical Field

[0001] This invention relates to the field of automated testing technology for substation power modules, and specifically to an integrated intelligent testing method and system for power supply basic modules. Background Technology

[0002] Currently, the industry has very strict testing requirements for equipment related to smart substations. The research and development of testing equipment for the entire life cycle of related equipment, from product manufacturing to on-site commissioning, is becoming increasingly sophisticated. Research results on testing related equipment for smart substations are emerging one after another. The research approach has gradually shifted from discussions on manual testing methods to technical approaches such as automated or intelligent testing using advanced software.

[0003] To improve the efficiency of relay protection device R&D testing, some literature proposes a design and implementation scheme for a relay protection R&D process testing system based on deep decoupling and sharing of test data. The system adopts an interval operation mode design, which improves the efficiency of R&D testing. Other literature takes low-voltage protection devices as pilot projects, using industrial robots to achieve intelligent handling, designing test production lines to achieve online device circulation, and developing supporting flexible intelligent test stations, etc., to improve the testing efficiency of relay protection in the production stage. In response to the situation where faults in secondary circuits of intelligent substations lead to incorrect operation of high-voltage circuit breakers, some literature proposes a fault tracing method based on a directed bipartite graph model, which can reverse trace the specific causes of incorrect operation of high-voltage circuit breakers, thereby improving the detection efficiency of secondary circuits.

[0004] The integrated AC / DC power supply for intelligent substations serves as an uninterrupted AC / DC power source for power automation, communication systems, remote execution systems, circuit breaker operation, relay protection, automatic devices, and signaling devices, playing a crucial role in the stable operation of intelligent substations. However, research on related automatic testing technologies is scarce. Currently, the following problems exist in the production testing of the basic modules (charging module and communication power module) of the integrated power supply for intelligent substations:

[0005] 1. The module testing process requires frequent manual switching of debugging equipment, which is time-consuming and labor-intensive;

[0006] 2. Module testing requires manual calculation and compilation of test reports; it cannot be digitized.

[0007] 3. The overall testing time for the modules was too long;

[0008] 4. The overall efficiency of module testing is not high;

[0009] 5. The testing quality of module products cannot be effectively guaranteed;

[0010] Therefore, it is necessary to study the automatic testing technology of integrated power supply basic modules, and the industry is constantly exploring ways to improve the testing efficiency of integrated power supply basic modules.

[0011] To improve testing efficiency, a patent with publication number CN113238162A, entitled "An Integrated AC / DC Power Supply Testing Method," includes a soft-start testing method for an integrated power supply charging device, a testing method for an integrated power supply battery, a testing method for an integrated power supply efficiency, and a testing method for an integrated power supply harmonics. This method utilizes an integrated AC / DC power supply system, which integrates all the necessary testing equipment. During testing, there is no need to change testing equipment, thus consolidating resources, saving testing time, and improving testing efficiency. This integrated AC / DC power supply testing method can perform all electrical performance and protection function tests according to relevant standards, and can also achieve semi-automatic testing and analysis. However, this patent has the following problems: it does not provide a simple and easy-to-use universal model for test data in the complex integrated power supply basic module testing process, failing to meet the needs of rapid test development for new products; it cannot perform fully automated testing on multiple integrated power supply basic modules, resulting in very limited improvement in testing efficiency; and the test results cannot provide effective digital test reports, which cannot be linked to orders to achieve overall result analysis across the entire testing workflow.
