So as to ensure the normal operation of transformer device and reduce the heavy loss caused by fault, a dynamic self-test skill of transformer device in smart muscle vegetation under the optimization of protection logic is proposed. The protection logic optimization scheme is proposed, and the single column three winding architecture of the main transformer of the smart muscle vegetation transformer device is constructed. On the basis of this architecture, according to the four arm thermal conductivity pool architecture and the wavelet denoising process, the performance self inspection system of the smart muscle vegetation transformer device is designed. According to the load model of the smart muscle vegetation transformer, Thus, the dynamic self-test skill of smart muscle vegetation transformer device under the protection logic optimization is realized. The laboratorial consequences show that the frequency response curves of the faulty winding and the winding under normal operation are basically the same, which can accurately diagnose the short circuit fault between turns of the transformer, and the self-test skill has strong test sensitivity.
