摘要
通过深入研究Matlab中电力系统模块集(PSB),特别是在同步电机模型的建模原理和工作机理的前提下,把以仿真信号形式输入的励磁电压改为以功率形式输入的励磁电源,以及把机械功率输入改为转速输入,得到了适于转速给定同步电机仿真的新模型.该模型具有与实际同步电机相似的励磁绕组输入端口和三相绕组输出端口,非常逼真地模拟了实际同步电机.利用新模型对带整流负载同步发电机进行了建模和仿真分析,结果说明,本文提出的方法简捷有效.
Matlab/PSB (power system blockset), especially the modeling principles and operation mechanism of synchronous generators are deeply analyzed. By substituting PSB exciting power input and mechanical speed input for simulink exciting voltage input and mechanical power input of the original synchronous generator model respectively, a new simulation model for a synchronous generator with a given speed is obtained. With the same input ports for the exciting windings and the same output ports for the threephase windings as a real synchronous generator, this model can simulate an actual synchronous machine exactly. Employing the proposed model, modeling and simulation for a synchronous generator with a rectified load is performed. The results confirm that the proposed method is effective.
