摘要:
城市轨道车辆产生的制动能量通过多模块并联变流器回馈至交流电网加以再生利用,但存在环流和谐波等问题。文章针对城市轨道制动能量回馈用多模块并联变流器的工况条件,设计了一种基于载波移相并联方式的双闭环控制策略,其外环控制直流母线电压,内环控制功率,能将直流母线能量迅速回馈至电网,提高了变流器的动态响应速度;通过调节变零矢量的分配时间,改进空间矢量调制方式,能够减小模块间的环流,提升变流器使用容量;最后运用载波移相的脉冲触发方式,减少了变流器并网电流的谐波。仿真结果表明,所提出的控制策略具有动态响应速度快、谐波率低、环流小等优点,符合城市轨道制动能量回馈用并联变流器的工况要求。
Abstract:
Braking energy can be fed back to the grid by the metro braking energy feedback converter using multiple power modules in parallel, but there are some problems such as circulating flow and harmonics. In this paper, a dual closed-loop control strategy based on carrier phase-shifting parallel mode was designed according to the operating conditions of multi-module parallel converters for urban rail transit energy feedback. Its outer loop is used to control the DC bus voltage and the inner loop is used to control power. The DC bus energy can be quickly feed back to the grid to improve the dynamic response speed of the converter. By adjusting the distribution time of zero-vector and improving the space vector modulation mode, the circulating flow between modules can be reduced and the capacity of converter can be improved. A pulse phase triggering method based on carrier phase shift was used to reduce the grid-connected harmonic current of the converter. Simulation results show that the proposed strategy has the advantages of fast dynamic response, low harmonic rate and small circulation, which meets the requirements of the parallel-converter for urban rail transit energy feedback.
