【摘要】 一种自适应配电网电压补偿装置,能比常规手段更有效地自适应补偿配电网末端电压偏低及三相电压不平衡现象,显著提高配电网供电质量。该装置采用三相自适应独立电压注入补偿技术;基于IGBT的AC-AC功率变换技术和针对SPWM的滤波器设计技术;基于快速故障检测和可靠旁路(<10ms)的高可靠性设计技术。自适应补偿电压注入,使末端电压升高,同时可以有效地解决三相电压不平衡问题。若植入储能环节,还可以实现重要负载的低电压穿越。更多还原

【Abstract】 An adaptive distribution network voltage compensation device can compensate the voltage of the distribution net-work with low voltage and three-phase voltage imbalance more effectively than the conventional method,and improve the power sup-ply quality of the distribution network. The device uses three-phase adaptive independent voltage injection compensation technolo-gy;IGBT-based AC-AC power conversion technology and SPWM filter design technology;based on rapid fault detection and reli-able bypass(<10 ms)of high reliability design technology. Adaptive compensation voltage injection,so that the terminal voltage in-creases,and can effectively solve the three-phase voltage imbalance problem. If the implantation of energy storage links,but alsocan achieve important load of low voltage through.更多还原
