| 摘 要： | 本文根据基本电机方程推导出双Y同步发电机带整流桥负载时的特性。同步发电机定子的两个Y形绕组移相30°电角度或者同相位,每个Y形绕组经两个三相桥式整流后相串联或并联,再加到负载上,从而可以构成四种运行方式。根据基本电机方程,导出了双Y同步发电机在这四种运行方式下位移角和换相角的表达式。因而在已知负载电流、励磁电流、发电机转速和电机参数时,可以预测带整流负载时双Y同步发电机的特性。用一台试验电机测得实验结果,并与理论分析和计算结果相比较。

| Abstract: | The characteristics of a double-star synchronous generator with rectifier load have been studied from the fundamental machine equations in this paper.The generator is with two statoric windings shifted by 30 or 0 eiectrical degrees, which with their bridges car. be connected either in series or in parallel. Therefore, the double-star synchronous genera- tor with rictifier load cm form four operating modes. From the fundamental machine equations, the expressions of displacement angles and commutation angles are derived under these operating modes Then the characteristics of a double-star synchronous generator with rectifier load can be predicted from given load current, field current, genrator speed, bridge delay angle and parameters. Theoretic results are compared with experimental results obtained from a laboratory macine. |
