Study of the active power exchanging between dynamic voltage restorer and the distribution power system

摘要

Dynamic Voltage Restorer (DVR) is an effective solution for transient voltage problems. The interaction model has been established between power system and voltage source inverter based series dynamic voltage restorer. On the basis of that, the flowing of energy exchanging between the DVR and the system are discussed in detail, which provides a strong theoretical basis for the design of DVR system.
