摘要：
Aiming at high-end sensitive users with higher power quality requirements, a voltage reconfiguration power quality integrated control device based on BESS is studied. The device adopts back-to-back chain topology with BESS and double power supply to improve the reliability of power supply. The topological structure and mathematical model are analyzed. A control strategy of phase separation and constant voltage is proposed for the dual power supply and chain structure of the device. Taking a set of 1MVA/10kV voltage reconfiguration chain power quality comprehensive treatment device as an example, the simulation model of the device is built under PSCAD/EMTDC, and the control effect of the device on voltage sag, harmonic, three-phase unbalance, frequency change, voltage interruption, load side sudden change and unbalance is verified. The control effect is realized. Source-load decoupling can effectively improve the quality of power supply.
