摘要
经技术改造,农网电压质量有所提高,但波动范围仍然超出国家规定允许值,制约农村经济的发展。文章研究一种基于固态继电器的采用对农网配变电压器调压绕组正反串联,实现稳定农村电网电压目的的无触点有载调压分接开关的接线及其控制方式。理论分析与模拟实验表明,这种稳压技术具有调压范围大,元件实际承受电压低,结构简单的优点,适用于农村电网。
Through technical reconstruction, the rural power grid voltage quality has been improved. But the voltage fluctuation range is still lager than the allowable value of national regulation. This situation seriously restricts the development of rural economy. This paper studied a non-contact on-load voltage regulation tap changer wiring and its control method. Used the way of connecting the regulating windings of distribution transformer positive and negative to achieve the goal of stabilizing the voltage of rural power grids. Theory analysis and simulation experiment manifested that this stabilizing voltage technology had advantages of large voltage regulating range, low actual beard voltage of elements and simple structure. And this technology was suitable for rural power grid.
