[0002] The generator wire rod is the core component and an important part of the hydro-turbine generator set, and its performance directly affects the overall operation of the generator. Therefore, conducting simulation tests on the generator wire rod to understand its performance in the actual working environment is of great significance for improving the operating efficiency of the generator and reducing the failure rate. Traditional generator wire rod simulation test platforms often use simple mechanical or electrical control, which makes it difficult to achieve precise adjustment and intelligent control of environmental parameters. During the test, fluctuations in environmental parameters may lead to deviations in the test results, which in turn affects the accuracy of the performance evaluation of the generator wire rod. In addition, traditional test platforms can usually only simulate a single or a few environmental parameters, and cannot fully reflect the various complex environments that the generator wire rod may encounter in actual operation.

[0003] With the rapid development of intelligent technology, more and more fields are beginning to introduce intelligent technology to improve work efficiency and accuracy. In the field of generator bar simulation test, the introduction of intelligent technology can achieve precise control of environmental parameters and improve the reliability of test results. At the same time, by introducing a variety of sensors and data processing technologies, the intelligent test platform can also monitor and record various data during the test in real time, providing strong support for subsequent performance analysis and optimization.

[0004] At present, there is still a lack of a test platform on the market that can fully simulate the operating environment of generator wire rods and realize intelligent adjustment of environmental parameters. Therefore, the development of a generator wire rod simulation test platform and its test method with intelligent adjustment of environmental parameters is of great significance for improving the accuracy of performance evaluation of generator wire rods and promoting the innovative development of generator technology.
