基于变频变压器的异步联网和潮流控制（VFT Based Asynchronous Grid Interconnection and Power Flow Control）
变频变压器 异步联网 潮流控制
2010/8/17
分析了变频变压器（variable frequency transformer，VFT）异步联网和控制潮流的基本原理，建立了VFT稳态运行时的数学模型，设计了VFT的转子转速控制器和传输功率控制器。然后，利用PSCAD/EMTDC软件，进行了VFT在传输功率跃变和短路故障下的仿真实验。仿真结果表明，VFT能够平稳地连接两个频率不同的异步电网，准确地控制电网间传输的潮流，并能够减轻一侧电网故障对另一...

NEW POWER OPTIMIZATION POSSIBILITIES OF STATIC CONVERTER AND ASYNCHRONOUS MOTOR DRIVING SYSTEMS
nonsinusoidal regime distortion power optimal control
2010/1/12
In this paper there are given a few mathematical relations for the power
analysis in un-sinusoidal regime. If the voltage is sinusoidal and the current is unsinusoidal,the apparent power will be asce...
