摘要
合并电路是磁流体(MHD)发电功率调节系统的关键技术之一。本文给出了MHD通道的简化等效电路模型,它和LC合并电路组成一个多回路电网络。利用状态方程的数值解对该网络的输出特性进行了分析,并对可关断晶闸管(GTO)的切换须率、LC元件的组合、合并的电极对数等参数对该网络特性的影响进行了仿真。合并电路的试验在由直流发电机、整流电源等构成的模拟MHD通道上进行。在累计40h以上的试验中,系统运行稳定可靠,试验结果与理论分析基本一致。
Consolidation circuitry is one of the keys for MHD power condi-tioning system. In this paper, a network model consisted of MHD channel equivalent circuit and LC consolidation circuit is presented. The numerical solution of state equation is applied to analyze the output characteristic of the network. In consideration of the effect of some parameters, for instance,GTO switch frequency, the number of consolidating electrodes, inductance and capacitance, on the characteristic of the network, the simulation is carried out. The experiment is performed in an analogue MHD channel which consists of some DC generators and other components. In the experimemts accumulated for more than 40 hours, the operation of the system is stable and reliable.The theoretical analyses and simulation are in agreement with the result of experiments.
