In recent years, non-linear loads on the distribution side are increasing rapidly. Notably, the electric arc furnace (EAF) is the most used non-linear load due to its diverse applications for industrial needs. However, EAF has some disadvantages like uneven distribution of heat inside the furnace, release of unwanted gases, increased level of harmonics, and Flickers in voltages. Specifically, power quality concerns are more and need comprehensive solutions. In this work, a matrix converter (MC) along with static VAR compensator (SVC) is proposed, and the hybrid exponential-hyperbolic furnace model is adapted in MATLAB platform. Simulations are carried out for different cases and the observed results are compared with existing methodologies. It was perceived that the power quality parameters such as peak current and voltages, total harmonic distortions (THDs), voltage flickers, and power factors are enhanced compared with existing methodologies. Precisely, the THD of current and voltage attains a prime rate of about 2.85% and 29.54%, respectively. Moreover, the proposed model’s voltage flicker and power factor offer a grander scale of about 1.26% and 0.9975, respectively. The enhanced scheme provides more significant advantages to the large-scale steel manufacturing plant with EAF.

使用矩阵转换器和静态无功补偿器提高电弧炉的电能质量

近年来，配电侧的非线性负载正在迅速增加。值得注意的是，电弧炉（EAF）由于其满足工业需求的多种应用而成为最常用的非线性负载。但是，EAF有一些缺点，例如炉内热量分布不均匀，释放有害气体，谐波水平增加以及电压闪烁器。具体而言，对电能质量的关注更多，需要全面的解决方案。在这项工作中，提出了一个矩阵转换器（MC）以及静态VAR补偿器（SVC），并在MATLAB平台中修改了混合指数双曲炉模型。针对不同情况进行了仿真，并将观察到的结果与现有方法进行了比较。人们认为，电能质量参数，例如峰值电流和电压，与现有方法相比，总谐波失真（THD），电压闪烁和功率因数得到了增强。准确地说，电流和电压的总谐波失真分别达到约2.85％和29.54％的最优惠利率。此外，提出的模型的电压闪变和功率因数分别提供了约1.26％和0.9975的较大比例。改进后的方案为具有电弧炉的大型钢铁制造厂提供了更多的显着优势。
