基于不平衡补偿的低压配电网电能质量问题及治理对策研究OACSTPCD
Research on Power Quality Problems and Countermeasures of Low Voltage Distribution Network Based on Unbalance Compensation
针对目前电力电子化配电系统三相负荷不平衡、电能质量下降及谐波分散等问题,提出一种动态响应快及输出谐波小的电能质量综合治理方案,其包括综合治理方式和复合重复控制策略.通过算例分析可知,在特定次谐波补偿模式中发现补偿前后谐波含量减少;不平衡电网补偿后电流畸变消除且电压电流同相位,这说明了综合治理的有效性.在实验验证中,所提方案可实现25 kW感性无功到25 kW容性无功的连续输出,满足技术指标中无功调节-100%～100%的要求,且输出功率与指令值偏…查看全部>>
Aiming at the problems of three-phase load imbalance,power quality degradation and harmonic dispersion in current electronic power distribution system,a comprehensive power quality control scheme with fast dynamic response and small output harmonic was proposed,which includes comprehensive control mode and compound repeat control strategy.By example analysis,it is found that harmonic content decreases before and after compensation in a specific subharm…查看全部>>
