摘要
随着社会的发展和用户对用电质量要求的提高,传统的机械式有载调压方法已经不能满足现代电网的安全和经济运行的要求,现有的交流电压调节器又存在一些不足。鉴于此,提出了一种基于电力电子的新型有载调压变压器,它结合了传统有载调压方法和交流电压调节器两者的优点,又克服了各自的缺点,是一种很有前途的电压调节设备。分析了新型有载调压设备的原理、主电路及控制策略,通过实验验证得出了相关结论。
With the development of society and sharp increase of electricity consumption, the electric power networks become much huger and more complex.The on-load tap changers of mechanism can not satisfy the requirements of power systems,security and economical operation in the case,and the AC voltage regulators still have much ;,disadvantage.For reasons given above,a novel non-contact on-load tap changing technology was presented,which was the combo of transformer and power electronic.It can improve the on-load tap-changable transformer performance.In this paper, the principle and scheme are introduced and analyzed.At the same time ,some circuits are given.Finally, experiment confirms the abovementioned claims.
