The Configuration of Medium Voltage Distribution Transformer for Extremely High Voltage Laboratory

Transformer is the most important component in power distribution design, and its long-term operation cost determines the operation cost of power distribution system. Therefore, it is necessary to analyze the transformer configuration considering efficiency and economy for extremely high voltage laboratory, which is used for study the lightning impact and protection of aircraft. In this paper, a medium voltage distribution system is designed to adapt the operation of extremely high voltage laboratory for lightning test. We analyze the basic information such as the type of distribution transformer, power loss and core material Then the model and capacity selection of the transformer are calculated and compared based on the actual load category and operation curve. According to the above analysis, a transformer configuration network with the lowest total cost in thirty years is proposed. This scheme provides the technical support for the implementation of aircraft lightning protection experiments. At the same time, the research can also be extended to power generation and distribution, laboratories or buildings with similar power architecture, which has promising application value.
