摘要:

主要介绍了应用于低压配电网三相四线系统的配电网有源电力电子补偿装置，分析了直接检测基波有功电流分量的基本原理。利用此种控制方式的配电网有源补偿装置在谐波、无功方面的补偿特性，尤其在配电台区负荷不平衡情况下，通过在Matlab/Simulink环境下仿真，证明此种配电网有源补偿装置检测控制方法的可行性和对三相负载不平衡情况下的良好补偿特性。最后通过开发样机证明了此种理论在补偿配电台区无功及三相电流不平衡情况下的有效性。

Abstract:

This paper mainly introduces an active power electronic compensation device of a power distribution network applied to the low-voltage power distribution network three-phase four-wire system and analyzes the fundamental principles of direct detection on the fundamental wave active current components. After the simulation in Matlab/Simulink environment by using the compensation characteristics of the power distribution network active compensation device in this control mode in the harmonic and reactive aspects, especially on the condition of unbalanced load of the power distribution station area, this paper proves the feasibility of the detection control method of the active compensation device and the good compensation characteristic in the condition of unbalanced three-phase load. Lastly, this paper proves the validity of the theory on the condition of reactive compensation power distribution station area and unbalanced three-phase currents.

Key words: power distribution network active compensation device unbalanced load low-voltage power distribution station area Simulink
