摘要:

为了解决电网电压相序不正确,三相电能质量调节装置无法正常工作的问题,提出了应用于三相电能质量调节装置的相序自适应方法。从三相电能质量调节装置的控制策略入手,研究相序的不同对三相电能质量调节装置控制的影响,对控制策略进行修改从而成功实现相序自适应。仿真和试验分别从正序和负序验证装置的不平衡、无功、谐波及间谐波补偿功能,验证了算法的可行性。

Abstract:

In order to solve the problem that the three-phase power quality adjustment device can not work normally due to the incorrect phase sequence of the grid voltage,a phase sequence adaptive method applied to the three-phase power quality adjustment device was proposed.This method starts with the control strategy of the three-phase power quality adjustment device,studies the influence of the different phase sequence on the control of the three-phase power quality adjustment device,and modifies the control strategy to successfully realize the phase sequence adaptive technology.The simulation and experiment verify the unbalance,reactive power,harmonic and inter-harmonic compensation functions of the device from the positive sequence and the negative sequence respectively,verifying the feasibility of the algorithm.

Key words: three-phase power quality adjustment device, phase sequence adaptive, distribution area, control strategy
