摘要
为保证输变电线路的稳定性,变压器电压的安全输出至关重要。因此,基于功率反馈模型,提出了输变电线路变压器电压平衡控制方法。首先,基于功率反馈模型构建变压器拓扑结构,使得无功与有功相分离地进行控制和调整,均衡地分配变压器的电压。其次,设计电压平衡整流器的有效范围。最后,进行输变电线路的电压平衡自动控制设计,保证输变电线路的每一单元听从同一功率的指令,进而完成电压的平衡控制。结果表明,基于功率反馈模型的输变电线路变压器电压平衡控制方法的实际应用效果较好,具有一定研究价值。
To ensure the stability of transmission and transformation lines,the safe output of transformer voltage is crucial.Therefore,based on the power feedback model,a voltage balance control method for transformers in transmission and transformation lines is proposed.Firstly,based on the power feedback model,a transformer topology is constructed to control and adjust reactive and active power separately,and to evenly distribute the voltage of the transformer.Secondly,design the effective range of voltage balanced rectifiers.Finally,the automatic control design of voltage active balance for transmission and transformation lines is carried out to ensure that each unit of the transmission and transformation line follows the instructions of the same power,thereby completing voltage balance control.The results show that the practical application effect of the voltage balance control method for transformers in transmission and transformation lines based on the power feedback model is good,and it has certain research value.
