MHD功率调节系统中的电流电极合并电路

A Current Collection Circuit for an MHD Power Conditioning

本文介绍一种利用补偿电源,以使具有不同端电位的电极,在不短路霍尔电势的条件下,将输出电流合并至一个公共点输出的电路。文中详细描述了电极电流合并电路CCC的结构及特征,推导了补偿电源结构为三相和六相反星形以及带有可关断器件的六相反星形情况下,CCC电路的无功功率及谐波电流与磁流体发电MHD通道电参数之间的关系,这种关系的建立为CCC电路的优化以及MHD功率调节系统中无功补偿、谐波吸收电路的设计提供了充分的理论依据。

In this paper, a structure of CCC was introduced. It, without short-circuit of Hall field,utilizes compensation source to consolidate electrode currents with different terminal potentials to a common point. The structures and features are described in detail, and the relationships between the reactive power, harmonics of CCC and MHD channel parameters are derived when the stuctures of CCC transformer secondaries are 3-phase wye, 6-phase double-wye and 6-phase double-wye with the turn-off devices. It provides a full theoretical basis for optimizing CCC and designing reactive power compensator and harmomic absorber.
