Research on Three-Winding Distribution Transformers Adapted to New Energy Power Generation Systems

With the continuous development of distributed new energy, traditional dual-winding distribution transformers struggle to meet the requirements for distributed power access and local consumption. This paper proposes a three-winding distribution transformer suitable for new energy generation systems. Through simulation analysis, its operational characteristics are compared with traditional dual-winding transformers, verifying its advantages in reducing copper losses, improving operational efficiency, and enabling local energy self-circulation in distribution areas. By reasonably designing the low-voltage winding structure, the transformer can adapt to multiple operating modes and AC-DC hybrid distribution networks, possessing good engineering application value.
