【摘要】 针对配电网台区三相不平衡、功率因数低、谐波污染和高线损等电能质量问题,结合当前配电网台区补偿设备的局限性和电能质量治理的不足,提出了基于双CPU的户外滤波补偿技术,可以达到精确无功补偿、相间平衡及谐波治理。经应用分析,配电网台区补偿技术能够全面解决配电台区中存在的电能质量问题,提高电压的稳定性和功率因数、平衡三相有功负荷、滤除电网系统中存在的谐波、降低线损。更多还原

【Abstract】 For the requirements of the current energy saving,according to the unbalance of three-phase load,low power factor,harmonic pollution and high line loss and other power quality problems situation in distribution network station area,combined with the limitations of the compensation equipment in current distribution network area and the inadequateness of power quality governance,an outdoor active filter compensation technology was proposed based on dual CPU,which can achieve exact reactive power compensation,white balance and harmonic control. According to the application analysis,the technology can is comprehensive solution in the power quality problems of distribution network area,can improve voltage stability and power factor,balance the three-phase active load,filter harmonic of grid system and reduce line losses.更多还原
