钢铁企业供配电系统电能质量控制解析

Analysis on Power Quality Control of Power Supply and Distribution System in Iron&Steel Enterprises

电压、波形、频率是钢铁企业供配电系统电能质量三要素,对安全运行,降低损耗和提高用电效率至关重要。从钢铁企业电能质量的现状入手,总结了特点并提出了改善措施。结果表明,钢铁企业电能质量目前是用电设备均有容量大、负荷冲击大,启动快速和工作连续等现状;采取的主要是改善电压差、治理电压波动、减少谐波影响等措施。实践证明,电能质量控制方案应该充分利用现有条件,因地制宜,因时制宜,制定最为符合实际的电能质量控制方案。

The voltage,waveform,and frequency are the three elements of power quality in the power supply and distribution system of steel enterprises,which are crucial for safe operation,reducing losses,and improving electricity efficiency.This article starts with the current situation of power quality in steel enterprises summarizes the characteristics,and proposes improvement measures.The results indicate that the current status of power quality in steel enterprises is characterized by high capacity,high load impact,fast start-up,and continuous operation of electrical equipment;The main measures taken are to improve voltage difference,control voltage fluctuations,and reduce the impact of harmonics.Conclusion:Practice has proven that the power quality control plan should fully utilize existing conditions,adapt to local conditions,and develop the most practical power quality control plan.
