Abstract

The increase in disturbances at frequencies higher than 10 kHz in medium voltage (MV) grids has led to new metrological challenges related to the accurate characterization of instrument transformers (ITs), which serve as the primary element in the measurement chain for the monitoring of these disturbances. In this context, this article presents a simple architecture of a generation system for the characterization of MV voltage transformers (VTs) up to 150 kHz under realistic power system waveforms. It is able to generate a MV tone at power frequency and superimposed disturbances having reduced amplitude and higher frequency. Unlike other approaches recently discussed in scientific literature that need two separate voltage sources, the main advantage of the proposed solution is the use of a single source, by suitably compensating its systematic errors through a simple compensation method. As first application, the experimental tests related to the characterization of two commercial VTs (LPVT), an inductive VT and a low power VT, are discussed.

一种低成本产生MV失真电压的方法用于高达150khz的VT表征

中压（MV）电网中频率高于10 kHz的干扰增加，导致了与仪表变压器（ITs）的准确表征相关的新的计量挑战，仪表变压器是监测这些干扰的测量链中的主要元素。在此背景下，本文提出了一种简单的发电系统架构，用于在实际电力系统波形下表征高达150 kHz的中压电压互感器（vt）。它能够在工频产生一个MV音调，并叠加具有降低幅度和更高频率的干扰。与最近在科学文献中讨论的需要两个独立电压源的其他方法不同，所提出的解决方案的主要优点是使用单个电压源，通过简单的补偿方法适当地补偿其系统误差。作为第一个应用，讨论了与两种商用VT （LPVT）特性相关的实验测试，一种是电感VT，一种是低功率VT。
