| 摘要: |
| 针对电力系统中操作复杂、效率低下和存在安全隐患等倒闸操作问题，设计出一种带负荷的电力系统柔性倒闸调节器。该装置主要是调节两个独立分列运行的配电母线电压，使两母线间产生逐渐变化的潮流，最终实现两母线电压趋向相等实现并列运行。设计了柔性倒闸装置的数学模型及拓扑结构，运用abc-dq变换进行前馈解耦的电流内环控制和PI调节的电压外环控制。通过Matlab/Simulink仿真验证了控制策略的快速性及准确性，能够保证用户用电可靠性及提高倒闸操作效率。 |

| Abstract: |
| Addressing the switching operation problems of complex operation, low efficiency, and potential safety hazards in a power system, a flexible power system switching regulator with load is designed. This device mainly adjusts the voltage of two independent buses for power distribution, so that a gradually changing current is generated between the two buses. Over time, the voltage values of the two buses tend to be equal to achieve parallel operation. The mathematical model and topology of the flexible switching device are designed. The abc-dq transformation is used to control the current inner loop control of feedforward decoupling and the voltage outer loop control of PI regulation. The rapidity and accuracy of the control strategy are verified by Matlab/Simulink simulation. This strategy can ensure the reliability for users and improve switching operation efficiency.
