摘要:

用Matlab建立了HL-2A装置的125MVA交流脉冲发电机组的超同步双馈调速方案中相关参数的仿真模型并进行了前期仿真。通过仿真分析给出了该方案的有关参数,并对启动过程进行了分析。对Matlab仿真库中的异步电机PU模型与变频器联结时存在不匹配的问题,提出用新的逻辑无环流控制方法解决并取得了较好的效果。该模型对于研究此类双馈变频系统提供了有益的参考。

Abstract:

A simulation modeling of double-fed motor speed regulation for 125MVA AC pulsed M-G set of HL-2A is built using Matlab. Some parameters of the project are obtained by the pre-simulation, and the process of start-up is analyzed. In the Matlab simulation the motor model in Simulink can not be connected directly to the cycloconverter model. This problem is solved by adding an ideal transformer model between them, and the satisfactory result is obtained. A new method of control switching two cycloconverter without circulating current has been introduced.

Key words: Cycloconverter, Switching without circulating current, Double-fed motor speed regulation
