On the basis of capacity determination, the brushless doubly-fed motor is chosen to replace the traditional motor in order to reduce the investment of speed regulation system, line loss and reactive power compensation device. For the type selection of transformer for station, the cooling mode, connection type, capacity and number of stations are determined as the research objectives. According to the operation condition of pumping station, the most suitable scheme is determined by technical comparison and economic comparison on the premise of defining the main connection type. Introducing modern technology, aiming at automatic control, fewer people on duty or no one on duty as the research goal, combining the four-in-one microcomputer centralized control device with the modern automation technology, and taking the water supply system in the water supply laboratory of Taiyuan University of Technology as the object, Carry out research and development. The main conclusions of this paper are as follows: 1) considering the number of pump motors and operation condition of pump station, the main connection is 6 kV, and the 0.4 kV side is single bus segment connection, in order to improve the reliability of system operation. In order to meet the requirements of electrical design, environmental protection and energy saving, the paper proposes to adopt single busbar sectional wiring mode, combined with the requirements of modern power system development. 2) in order to meet the safety of electrical design, environmental protection and energy saving in the transformer selection of the first stage station of Dayudu pumping Station, Fast requirement, considering that dry transformer has strong overload capacity and lightning shock resistance, and low loss, saving resources, saving space, convenient maintenance, this paper chooses the structure type of fully sealed transformer, which has the advantages of low loss, saving resources, saving space and convenient maintenance. The wiring mode is triangle type; 3) combining with the water supply laboratory of Taiyuan University of Technology, this paper discusses the water supply pump station, introduces the modern technology, realizes the combination of data collection and data analysis of the monitoring system, in order to improve the management level of the water supply system. This is the biggest innovation of this study. In the selection of transformer in pumping station, the influence of connection mode on transformer operation is studied. With the introduction of automation technology, if the main wiring can realize automatic detection and self-repair, it will save a lot of manpower and material resources. The above content is the direction of this research in the future.
