| description | Traditional on-load tap changer (OLTC) has problems such as easy oscillation and low regulation precision in the voltage regulation control of the power system. In order to seek a speedy and stable voltage control strategy, a flexible on-load voltage regulator is studied in this paper. A stepless energy take-off winding is set on the high-voltage side to connect the back-to-back converter, and the winding side of the converter is used to realize reactive power compensation. The grid side of the converter can realize continuous voltage regulation. A coordinated voltage regulation control strategy between flexible on-load voltage regulator and static synchronous compensator (STATCOM) is proposed. The tap positions of the flexible on-load voltage regulator and the reactive power sent by the STATCOM are used as reference signals to ensure sufficient capacity of the compensator and reduce the number of tap actions. The strategy proposed in this paper is compared with the voltage regulation method based on the traditional voltage regulation devices, the effectiveness of the strategy is demonstrated by some simulations based on Matlab/Simulink. |
