摘要
研究多并联支路型可控电抗器的工作模式是设计制造多并联支路型可控电抗器的基础。本文以二进制编码方式清晰地表示出了顺次单支路、转移单支路和固定单支路三种工作模式下各个晶闸管的全导通、全截止和触发角调节三种状态之间的转换规律,详细分析了上述三种工作模式下并联支路数、各支路额定电流、各支路谐波电流和谐波系数的计算方法和公式,举例给出了典型工况的仿真计算结果。结论表明这三种工作模式简单有效,各有特点,应根据实际情况加以选择使用。
Investigating the operation mode is the foundation of design and manufacture of a controllable reactor with multiple parallel branches. For the three operation modes, named step-single-branch operation mode, transfer-single-branch operation mode and fixed-single-branch operation mode, the rule which governs the transition between the complete conduction state, complete shutoff state and regulation state of thyristors is demonstrated clearly by the binary-coded notation, and the calculation methods and formulae of the branch numbers, the branch currents and the harmonic coefficients are proposed. Meanwhile, the results of simulation examples are given. It is put forward that all of the operation modes presented here are effective and efficiency, every one has own virtue, and which one is employed should be according to the practical situation.
