摘　　要：针对云浮供电局110kV良田站10kV母线谐波超出标准,无功补偿装置串联电抗器出现过载损坏的情况,本文通过建立系统等值电路,分析实地谐波检测数据,实际运行数据,计算电容器中的谐波电流分量;验证了谐波对无功补偿装置造成的影响,结合实际情况及运行经验,提出4项抑制谐波电流的治理措施建议,对比各项措施优缺点,得出综合治理方案。经实际运行验证,所提措施具有良好的经济性和可行性,为后续的云浮地区电网谐波治理研究提供了理论支持和实践经验。This paper is based on the grid of Yunfu, the harmonics of the 10 kV bus exceeds the standard and the reactor of reactive power compensation device is damaged caused by overload in the 110 kV Liangtian power substation. The paper builds the system equivalent circuit, analyzes the field testing data of harmonic and actual operation data to calculate the total harmonic current in the capacitor. The influence of harmonic on reactive power compensation device is verified. Based on the actual power operating mode and experience, the paper suggests four recommendations to eliminate current in the capacitor. Compared the advantages and disadvantages, it gets the comprehensive improvement plan, it is verified by actual operation. The proposed measures have good economy and feasibility. It provides theoretical support and practical experience for the follow-up research on harmonic control of Yunfu power grid.
