Description

Technical Field

[0001] The present invention belongs to the technical field of pressure testing, and in particular relates to a pressure testing method and system for a power communication protocol software system. Background Art

[0002] With the rapid development of society, the requirements for the stability and health of smart grids are becoming increasingly higher, and the requirements for dispatching master stations and plant stations are also becoming increasingly higher. The integrated monitoring system and dispatching master station system in the substation are the main equipment of the smart grid, and their fast and stable communication is particularly important.

[0003] The power grid is a real-time control system. Its generation, transmission, and consumption occur instantaneously, making it impossible to store or temporarily transfer power. Due to the sheer volume of data involved, a "data avalanche" can occur when a grid failure or disturbance occurs. In such situations, the ability to correctly transmit commands and display relevant information becomes a crucial indicator for maintaining grid stability. Furthermore, in unmanned substations, the recording and storage of fault information can significantly support fault analysts, enabling them to make informed decisions about the problem.

[0004] The traditional stress test method is to prepare multiple actual measurement and control devices, use air switches to uniformly control the telesignaling points of the measurement and control devices, simulate data avalanche by manually changing the position of the air switches, and finally query on the interface whether the number of received signals is consistent with the number of position changes.

[0005] This traditional approach often requires testers to repeatedly operate air switches to simulate data avalanches. If problems arise that are related to the number of times the test is repeated, this can require significant time and repeated testing. The most critical issue is that this traditional approach, through repeated retesting, makes it difficult to identify the actual stress boundary of the software system itself. In practice, repeated testing is often the only way to ensure that the system under test can withstand the stress data volume within a specified timeframe. This is primarily due to the multi-process, multi-threaded environment of the operating system, where information collection, processing, and upload depend on the processing times of different devices. This is fundamentally due to the uncertainty of external I / O and network latency in the communication system, which leads to uncertainty in the operating system's scheduling. As a distributed system, this leads to inconsistent stress data execution sequences, ultimately making it difficult to locate the stress boundary. Summary of the Invention
