Recently, China Xidian successfully developed the first high-performance 220kV70MVA series transformer in China. This high-tech product is the key equipment designed and manufactured by China Xidian for Nanjing 220kV West Ring Network unified power flow controller engineering.
At present, the power grid generally has problems such as unreasonable power flow distribution and inflexible operation, which affects the power transmission capacity of the power grid. There is an urgent need for a new technical means to flexibly and dynamically adjust the system voltage and current flow, and improve the ability of the power grid to control. The Unified Power Flow Controller (UPFC) can effectively solve this series of problems. The series transformer is an indispensable important equipment in the unified power flow controller UPFC project, and the market prospect is very broad.
Since the high-voltage side winding of the product is connected in series in the 220kV line, the high-voltage first-end and end-to-ground insulation levels need to be designed according to the line voltage level, and the requirements for the series transformer's short-circuit resistance and overload capacity are much higher than those of conventional products.
On the basis of the successful experience in the design and manufacture of 220 kV conventional transformers, the technicians of Xidian Xichang Company of China Xidian will carry out scientific research and technological innovation for key technologies and key difficulties in design, manufacture and transportation of series transformers. Conducted comprehensive analysis and verification of electric field analysis, magnetic field analysis, hot spot temperature rise, short circuit resistance analysis, noise and other systems to ensure the reliability of the product design and advanced technology. The product has passed routine tests and type tests not long ago.
The successful development of this product enriched the types of XD brand transformer products, provided new ideas for the optimization of power systems, met the requirements of high-quality power supply, energy saving and environmental protection for power systems, and laid the foundation for the subsequent research and development of series transformers with higher voltage levels. The foundation has greatly enhanced the competitiveness of China Xidian in the series transformer market.
