| 摘 要： | 就动态电压恢复器和配电静止同步补偿器对电压暂降的补偿技术进行了详细的计算分析，分别通过注入最小电压和注入最小电流确定了装置的最小补偿容量，从而方便装置的设计和控制。同时分析表明，在考虑极端情况即没有超级电容器储能单元时，电压暂降的补偿并不总能实现，因此采用超级电容器作为储能单元的动态电压恢复器和配电静止同步补偿器在提高电能质量方面有重要作用。

| Abstract: | The compensating techniques of voltage sag by DVR(Dynamic Voltage Restorer) and D-STATCOM(Distribution system STATic synchronous COMpensator) are analyzed and calculated in detail,and the minimum compensation capacity is determined respectively by minimum voltage injection and minimum current injection,which simplifies the design and control of device. The ana-lysis also shows that the compensation of voltage sag is not always practical with the extreme case of without super capacitors. DVR and D-STATCOM with super capacitors as their energy storages can play an important role in power quality improvement. This project is supported by Portrait Sci. and Tech.
