项目摘要

The purpose of this research was to develop a new voltage regulator using the orthogonal-core type variable inductor. As the voltage regulator is connected to high voltage power distribution line in series, reliability is most important. The application of the orthogonal-Core type variable inductor to the series voltage regulator is expected because the variable inductor has desirable features including simple construction, high reliability, easiness of control and low harmonic currents. In this research, the author clarifies the operating characteristics of the variable inductor, and makes a proto type voltage regulator. The obtained results are as follows :(1)Analysis of the operating characteristics. The orthogonal-core type variable inductor utilizes a nonlinear B-H characteristic of magnetic core. Furthermore, the orthogonal-core has complicate flux distribution. For this reason, it was difficult to analyze quantitatively the operating characteristics of the orthogonal-core type variable inductor. In this research, the author proposes a new calculation method based on 3-dimensional nonlinear magnetic circuit. The calculated results and experimental ones show good agreement. The analytical method is useful for optimum design of the orthogonal-core type variable inductor.(2)Trial construction of variable inductor. Based on the above results, the author made a 1kVA proto type voltage regulator using the orthogonal-core type variable inductor. Experimental results indicate that the trial voltage regulator has good controllability and low harmonics. The voltage regulator developed here is useful for stabilizing the complicated power distribution system.

本研究旨在开发一种使用正交铁芯型可变电感器的新型电压调整器。由于电压调节器与高压配电线路串联，可靠性最为重要。正交磁芯型可变电感器具有结构简单、可靠性高、易于控制、谐波电流小等优点，有望应用于串联型电压调节器。本研究阐明可变电感器的工作特性，并制作一个原型电压调整器。主要研究结果如下：（1）运行特性分析。正交磁芯型可变电感器利用磁芯的非线性B-H特性。此外，正交磁芯具有复杂的磁通分布。因此，难以定量地分析正交磁芯型可变电感器的工作特性。在本研究中，作者提出了一种新的计算方法，基于三维非线性磁路。计算结果与实验结果吻合较好。该分析方法可用于正交磁芯型可变电感器的优化设计。（2）可变电感器的试制。在此基础上，作者用正交磁芯型可变电感制作了一个1 kVA的原型调压器。实验结果表明，该调压器具有良好的可控性和低谐波。所研制的电压调节器对稳定复杂的配电系统具有一定的实用价值。
