“雪龙2”号极地考察船电力系统电压降计算分析

Calculation and Analysis of Voltage Drop of Power System of the Snow Dragon Ⅱ Polar Survey Vessel

基于自耦变压器启动条件及启动压降允许值指标,分析了基尔霍夫定律在电动机全压启动计算中的优势。并以"雪龙2"号极地考察船为实例,验证了该方法在自耦变压器启动电压降计算和校验工程实际应用中的可行性和准确性。

Based on the starting conditions and the voltage drop allowable value for the motor starting,the advantages of the Kirchhoff law in the calculation of the starting voltage of the motor are analyzed. Taking the Snow Dragon II Polar Survey Vessel as an example,the feasibility and the accuracy of the Kirchhoff law method in calculation and verification of the motor’s voltage drop under full-voltage starting mode are presented.
