电子式电压互感器在现代变电站中的应用探讨

Discussion on the Application of Electronic Voltage Transformer in Modern Transformer Substation

现代社会生活生产对电网的运行质量提出了更高的要求,而变电站作为电网的重要组成部分,对电网整体运行的安全性、稳定性以及效率等具有极大的影响。传统的变电站所使用的互感器为电磁式电压互感器,在长期的使用过程当中发现其具有易发生磁饱和、动态范围小以及绝缘性能差等缺点,而且它只能够输出模拟信号,这对变电站及电网的运行、管理和维护来说都是较为不利的。电子式互感器作为更加先进的电压互感器,克服了传统电磁式电压互感器的种种缺点,将其应用到变电站当中,可以显著提升变电站与电网整体的运行、管理和维护质量。本文基于作者自身的实际工作与学习经验,首先简单分析了电子式电压互感器的分类、组成和性能,然后主要对电子式电压互感器在现代变电站中的应用进行了分析探讨,以期能对电子式电压互感器的推广、应用与普及起到促进作用,提升变电站和电网整体的运行、管理和维护质量,保障社会生活、生产用电。

The modern social life quality of the production run on the grid put forward higher requirements, and the substation as an important part of the grid has a great impact on the overall operation of the power grid safety, stability and efficiency, using the traditional transformer substation for electromagnetic voltage transformer, which is prone to faults magnetic saturation, small dynamic range and poor insulation are found in the process of long-term use, but it can only output analog signals, the substation and power grid operation, management and maintenance are more is not good for. Electronic transformer for voltage transformer is more advanced, it overcomes the shortcomings of traditional electromagnetic voltage transformer, applied to substation, substation and power grid can significantly improve the overall operation, management and maintenance of quality. In this paper, the actual work and study based on the author＇s own experience, first introduced the classification of electronic voltage transformer components and performance, and then mainly analyzes the application of electronic voltage transformer in modern substation, in order to promote the application and popularization stage can mutual inductor of electronic voltage plays promote, improve the whole substation and power grid operation, management and maintenance of the quality guarantee, social life and production of electricity.
