How to strengthen the optimal configuration of distribution transformers
The protection configuration of distribution transformer mainly includes circuit breaker, load switch or load switch plus fuse. Load switch can save investment, but can not break short circuit current; The technical performance of the circuit breaker is good, but the equipment investment is high and the use is complex; The protection configuration mode of combination of load switch and fuse can avoid the use of circuit breaker with complex operation and expensive price. This paper briefly explains various protection configuration types of distribution transformer. Through analysis and comparison, it is proposed to strengthen the optimal configuration of distribution transformer protection and select a reasonable protection scheme, which can improve the reliability of distribution transformer protection action.

1. Design of power transformer simulation model
Under the programming environment of Matlab, this paper analyzes the current methods of transformer simulation. In the case of single-phase, the phenomenon of saturated and unsaturated inrush current and the characteristics of single-phase inrush current are analyzed. In the three-phase case, based on the piecewise fitting and curve compression method, the mathematical simulation models of three-phase transformers under the four most commonly used connection modes Yd11, Ynd11, Yny0 and Yy0 are established by using two modified arctangent functions and two modified arctangent functions plus two straight lines to simulate saturation, and are simulated in Matlab. By analyzing the waveform of three-phase inrush current and hysteresis loop, and the characteristics of three-phase inrush current, the main factors affecting the inrush current of three-phase transformer are summarized. Finally, the advantages and disadvantages of the two methods are analyzed, and a relatively perfect transformer simulation model is established.
