摘要
针对电网电能质量出现的谐波高频化、间谐波、电压暂降等新问题的主要特点,从柔性交流输配电装置、高压直流输电技术、可再生能源的大规模接入及变频调速装置的应用方面分析造成电能质量新问题的原因,并说明电能质量新问题带来的影响。
The nationwide power grid changes its status and causes several new power quality problems including high frequency harmonic,interharmonic,and voltage dip.The characteristics of these issues are summarized and concluded,the main reasons including application of flexible AC transmission device,application of high voltage DC transmission,large-scale connection of renewable energy sources,and usage of AC variable frequency speed control device.The influences of the new problems are studied in this paper.The key research and management directions are also discussed in the conclusion.
