摘要
智能电网的建设与发展对测量线路电压、电流的传感器提出了新要求。为了能在实验室模拟电网线路上同时存在高电压与大电流的情况,对研制的传感器进行实验测量,设计并验证了一套基于电磁感应原理,采用三相调压器和自耦变压器的高压大电流实验平台。该实验平台中线路上的电压、电流分别可调,能在实验中实现在不同幅值的电压、电流下测试传感器的测量误差。
New requirements are imposed on sensors for measuring line voltage and current by the construction and development of smart grids.In order to simulate,in the laboratory,the situation where high voltage and large current coexist on the power grid lines and conduct experimental measurements on the developed sensors,a high voltage and large current experimental platform based on the principle of electromagnetic induction and utilizing three-phase voltage regulators and autotransformers is designed and verified.On this experimental platform,the voltage and current in the lines are adjustable respectively.It enables the measurement errors of sensors to be tested under voltages and currents of different amplitudes during experiments.
