Research of laser and solar hybrid powered system for Active optical-electronic current transformer

Abstract

随着电力工业的不断发展,电网电压等级的不断提高,对电压、电流的测量要求也在不断提高。传统的电磁式互感器无法满足迅速发展的数字化电网电压的测试要求。目前电子式(光电式)互感器已成为电网中高电压、高电流测量新的研究热点,有源式光电电流互感器是新型互感器研究的典型代表,而高压端的供能是有源式光电电流互感器的关键部件之一。目前研究的主要有线圈从母线上取能、高压电容分压式供能、激光供能、蓄电池供能、超声电源供能等供能方法。 本文在光电互感器基本原理理论研究的基础上,对上述各种供能方法进行分析研究,结合激光供能、太阳能供能、蓄电池供能的优点提出并设计了一种新型的混合式供能设计方案,即激光和太阳能混合式供...With the continuous development of the Electric Power Industry, the Grid voltage level is rising.
