摘要
现代电力系统的逆变电源控制技术中,输电线路的阻抗特性通常假定为纯感性,而实际中线路电感存在一定阻性,一定程度上限制了均流控制策略的应用。针对此问题,提出一种基于功率完全解耦的逆变器并联控制策略,在同步旋转坐标系下分别对有功功率和无功功率进行完全解耦,实现了在任意线路特性下的逆变器并联功率解耦控制。通过建立逆变器并联的MATLAB仿真试验模型,验证了该控制策略具有良好的功率均分效果。
In the inverter control technology of modern power systems,the impedance characteristics of transmission lines are usually based on the ideal state of human hypothesis.Thus to some extent,it limits the application of flow balancing control strategy.Aiming at this problem,an inverter parallel control strategy is put up based on completely decoupled power.The active power and reactive power are completely decoupled under the synchronization reference frame respectively,which implements the parallel power decoupling control of inverters under arbitrary line characteristics.Through the establishment of inverters of the parallel MATLAB simulation test model,it is validated that the control strategy has a good power balancing effect.
