摘要
本文对并联电容器装置在谐波环境中的应用作了简要分析,指出在工程应用时必须要考虑系统、电容器补偿装置和谐波的相互作用,以避免谐波放大造成的设备运行故障,并通过实测数据对比给出了结论。利用等效电路图对谐波源位于供电系统电源侧或负荷侧的情况分别进行了推导计算,阐述了在谐波环境中并联电容器串联电抗器的必要性,对电抗率的选择提出了合理化建议。
In this paper, the application of shunt capacitors in the harmonic environment is briefly analyzed. It is pointed out that in the project application, the interaction of the system, capacitor compensation installation and harmonic must be considered so as to avoid equipment fault due to har- monic amplification, and conclusion is given through comparison of actually measured data. Such situation as harmonic source is at power supply side and load side of power supply system is derivat- ed and calculated respectively by the use of equivalent circuit, and the necessity of shunt capacitor and series reactor in the harmonic environment is explained and the reasonable suggestion on the re- actance rate is proposed.
