集成在智能电能表中的校准板的设计(中文5300字,英文3400字)
摘要
我们在本文中介绍了集成到智能电能表（SEEM）中的校准板的设计。事实上，我们提出了一种远程校准和现场校准的方法，其中电表根据电流参考值和电压参考值进行自校准。这些参考值应该由集成电源生成。所以我们在校准板中加入了一个转换器和一个交流负载。转换器用于将来自电网的电压（可变）转换为稳定且已知的参考电压，而交流负载用于设置电流值。设计的转换器是一种AC-DC-AC型，称为间接转换器。为了控制DC-AC模块开关，我们使用了基于前馈技术的数字技术。我们的AC-AC转换器设计通过MATLAB仿真验证，我们在额定值附近显示可变输入电压，输出电压在非常低的总谐波失真（THD）下保持稳定。

Design of a calibration board integrated in a smart electrical energy meter (hardware part)
Abstract—We present in this paper, the design of a calibration board integrated into a Smart Electrical Energy Meter (SEEM). Indeed, we proposed a method to calibrate remotely and on-site the SEEM, where the meter is self-calibrated based on a current reference value and a voltage reference value. These references should be generated by an integrated power source. So we included in the calibration board a converter and an AC load. The converter is used to convert the voltage coming from the electrical network, which can vary, to a reference voltage which is stable and known, while the AC load is used to set the current value. The designed converter is an AC-DC-AC type, called indirect converter. To control the DC-AC block switches we used a digital technique based on the feed-forward technique. Our design of the AC-AC converter is validated by a simulation on MATLAB where we show for a variable input voltage around a nominal value, the output voltage remains stable with a very low Total Harmonic Distortion (THD).
