| 摘 要： | 本文介绍了用于2MW直驱风力发电系统的自研全功率变流器的组成与设计，详细分析了该变流器系统所采用控制策略，认为在这一功率等级下，采用Us／fs=E0／fs矢量控制技术较常用的最大转矩／电流比控制更有利于系统的安全运行。同时，对其中的其它关键系统设计（通讯系统、系统保护与监控系统）做了说明。通过在风场的实际测试与运行，结果表明所设计的变流器系统能够满足设计要求，并配合整套风机系统实现最大功率捕获。

| Abstract: | In this paper, the design of power converters in 2 MW direct-driven wind power system is introduced ,especially, the control strategy is disscussed in detail. The maximum torque-current ratio control strategy is used for the sake of operation security. Other important engineering issues such as communication system, system protection and monitor system are also introduced here. The experiment results in field show that the system design can meet the conditions and the maximal power tracking is achieved perf... |
