| Abstract: | The self-excitation power supply is a self-power supply technology for electronic transformers at high voltage side.In this article,the design principles and configuration methods are introduced of adopting complete self-excitation power supply in high-voltage substation.A technical improvement process and actual operation effect are illustrated of 110 kV substation in Mianyang.It is shown that the application of complete self-excitation power supply transformers simplifies system structure,exempts from periodic maintenance requirements for power supply equipment,improves the stability of the operation.The expected service life increases from 1~3 years to 15~20 years.Therefore,it is worthwhile popularizing the power supply technology to a large scale. |
