摘要
文章以电能质量的工程项目为依托,对钢铁生产线中轧钢时会产生短时冲击无功、供电系统电压剧烈波动、功率因数较低的现象,采用了直流侧电压的平衡策略——基于分级控制的电压微控平衡策略,并提出了适用于高压、大容量领域的H桥级联结构的静止无功发生器SVG的方案。通过软件MATLAB/Simulink对方案实施前后进行对比,验证了所提方案的可行性。
Based on the project of power quality,the balance strategy of DC side voltage-voltage micro-control balance strategy based on hierarchical control is adopted to deal with the phenomenon of short-time reactive shock,violent voltage fluctuation of the power supply system and low power factor when rolling steel in the iron and steel production line.Besides,a SVG scheme of H-bridge cascade structure suitable for high voltage and large capacity fields is proposed.The feasibility of the proposed scheme is verified by comparing the results before and after the implementation of the scheme with the software MATLAB/Simulink.
