Description

[0002] The generator and main transformer protection transmission test of the hydropower unit is an important part of ensuring the safe and stable operation of the hydropower station. Traditional testing methods usually include no-load characteristic tests and short-circuit characteristic tests on the generator, as well as debugging and verification of the main transformer protection device. Although these methods can provide certain test results, they have some limitations in practical applications. For example, traditional testing methods may require complex equipment and long testing time, and the ability to monitor and adjust the equipment status in real time during the test is limited.

[0003] In addition, with the continuous development of hydropower unit technology, higher requirements are placed on the accuracy and reliability of test methods. For example, the shaft system detection and adjustment of large hydropower units require more accurate measurement methods, and the complexity of the main transformer protection algorithm also increases the difficulty of testing.
