中文摘要：
变压器式可控电抗器rcontrollable reactor of transformer type，CRT）的控制级数由功率递增系数确定，而谐波系数又决定着功率递增系数。定义了3种谐波系数，并定量分析了3种定义下的谐波系数与其控制级数之间的关系，给出了计算公式；进行了比较分析和算例计算。结果表明，在满足谐波电流有效值要求的前提下，分别由3种谐波系数定义计算的CRT控制级数依次减少，最大谐波电流有效值依次增大；并指出，从谐波电流有效值来看，由第1种谐波系数定义计算会导致过多的控制级数，是不合理的，而由第3种谐波系数定义计算的控制级数最少，是最合理的。论文工作为简化CRT结构奠定了理论基础，也为类似电气设备设计和谐波分析提供了参考。
英文摘要：
Power-step number of controllable reactor of transformer type （CRT） is determined by reactive power increment coefficient, and the reactive power increment coefficient is determined by harmonic coefficients. Three kinds of harmonic coefficients are defined, and the relationship between harmonic coefficients and power-step number is quantitatively analysed according to the three definitions, then the calculation formulas are given; the results of numerical examples are compared and analysed. The results show that, under the premise of meeting the harmonic current limiting requirements, the power-step number calculated according to the three definitions of CRT is decreased sequentially, and the RMS of maximum harmonic current is increased sequentially. At the same time, in view of the RMS of harmonic current, it is not reasonable that the harmonic coefficient calculated by the first definition will lead to too many power-step number, and it is the most reasonable that the harmonic coefficient calculated by the third definition will obtain the least steps. The work of this paper lays a theoretical foundation for simplifying the structure of CRT, meanwhile, provides a reference for design and harmonic analysis of similar electrical equipment.
