Generator rotor turn-to-turn insulation detection method, device and equipment and storage medium

Abstract

The embodiment of the invention discloses a generator rotor turn-to-turn insulation detection method, device and equipment and a storage medium. The method for judging the turn-to-turn insulation defect of the generator comprises the following steps: acquiring reference operation data and real-time operation data of the generator; determining reference electromagnetic power of the generator underdifferent exciting currents according to the reference operation data, and determining real-time electromagnetic power of the generator under different exciting currents according to the real-time operation data; and under the same exciting current, determining the turn-to-turn insulation state of the rotor of the generator according to the real-time electromagnetic power and a preset deviation threshold range, wherein the deviation threshold range is used for representing the deviation range between the reference electromagnetic power and the real-time electromagnetic power. According to theembodiment of the invention, quick real-time early warning of turn-to-turn insulation of the generator rotor is realized.

Description

technical field [0001] The embodiments of the present invention relate to electric equipment detection technology, and in particular to a detection method, device, equipment and storage medium for the inter-turn insulation of a generator rotor. Background technique [0002] In recent years, traditional generating sets will be deeply involved in the auxiliary business of the power system, which puts forward higher requirements for the performance and reliability of the generating sets. The generator rotor is an important part of the main equipment of the power plant, and its health status is of great significance to the safety and efficiency of the unit operation. [0003] Once the generator rotor fails, it will face greater safety risks, longer maintenance cycle, high maintenance cost and other issues. Therefore, domestic and foreign equipment manufacturers and power generation and manufacturing technology, and actively adopt advanced technology to monitor the head end to e...

Problems solved by technology

[0004] However, the above monitoring indicators cannot effectively reflect early faults such as slight short-circuits in the inter-turn insulation of the generator rotor, so early warning of faults cannot be carried out in a timely manner. Off-line test methods can only be used for detection, which increases the further development and aggravation of early faults, and even causes There are certain limitations and deficiencies in the risk of serious accidents such as non-stopping of the unit.
