Abstract

When the converter transformer is closed without load, a large impulse current may appear due to the saturation of the transformer core magnetic circuit, which is called the inrush current of the converter transformer. According to ± 800 kV UHVDC converter transformers in Tianshan converter station, this paper establishes electromagnetic transient simulation models, studies the characteristics of inrush current of charging transformers without loads in converter station, and analyzes the suppression effect of closing resistance and closing phase angle on inrush current. The results show that it is more appropriate to select the closing resistance of the circuit breaker for transformers to be more than 800 Ω when considering practicality and economy. When the closing resistor is used in combination with the phase selection closing, the optimum closing phase angle of the converter transformer is 18°, and the optimum closing phase angle of the main transformer is 54° The research results provide data support for ensuring the safe operation of Hami-Zhengzhou UHVDC project.
