Abstract

The article deals with the study of the compensatory properties of unified power quality conditioner in the complex voltage distortion case by external consumers on a voltage-restorer transformer. Unified power quality conditioner is constructed the topological scheme including series and shunt components. The analysis of known methods a voltage and current compensation determination is carried out. It is determined that the power theory in the structure of the unified power quality conditioner scheme can be rationally applied to a parallel filter-compensating device, and for series it is enough to use filtration methods. In the visual programming environment an electrotechnic complex model developed. Experiments to effectiveness determine of proposed design a unified power quality conditioner have been delivered. In the obtained data analysis, a decrease in voltage and current distortion was noted, but short-term voltage and current pulses remained because the series-connected transformer has a significant windings inductance, which degrades the overall quality indicators.

统一电能质量调节器电气综合体补偿急剧变化负荷的影响

本文研究了统一电能质量调理器在电压恢复性变压器外部用户复杂电压畸变情况下的补偿特性。构建了统一的电能质量调节器拓扑方案，包括串联和并联元件。对已知的电压和电流补偿测定方法进行了分析。确定了统一电能质量调理器方案结构中的功率理论可以合理地应用于并联滤波补偿装置，对于串联采用滤波方法就足够了。在可视化编程环境下开发了一个电工复杂模型。对所提出的统一电能质量调理器的有效性进行了实验验证。在获得的数据分析中，注意到电压和电流畸变有所减少，但由于串联变压器的绕组电感较大，因此短期电压和电流脉冲仍然存在，从而降低了整体质量指标。
