基于RTW的双向充放电机实时控制技术

随着智能电网和绿色能源技术的快速发展,双向充放电机也越来越受到关注;文章主要研究双向充放电机充电过程中电压的稳定性和放电过程中并网电流波形的畸变率;提出了一种基于RTW的matlab/simulink控制方法,在simulink环境下搭建仿真模型和控制模型,然后将达到预期效果的仿真模型所对应的控制模型编译为代码并烧写到DSP中;此种方法在能够保证在恒流源和恒压源两种充电模式中电流和电压的稳定性,在放电过程中并网谐波电流总畸变率小于5%,功率因数基本为1;仿真结果和基于DSP2812的硬件平台实验都证明了这种方法的有效性。

Based on the RTW of the Bidirectional charge discharge machine real-time control technology

With the rapid development of smart grid and green energy technologies, Bidirectional charge discharge machine is paid more and more attention.This paper mainly studies the voltage stability of Bidirectional charge discharge machine in the process of charging and The grid current waveform distortion rate of the discharge process. Put forward a control method based on RTW matlab/simulink. Build the simulink model and control model in the simulink environment.Then the code will be burned into the DSP processor complied from control model to the corresponding simulink model which achieved the desired effect.This method can guarantee the stability the current and voltage in the two pattern of the constant current source and the constant voltage source.In the process of discharge,the Grid-connected total harmonic current distortion rate less than 5%,the power factor is basic to 1.The simulation results and hardware platform experiment of DSP2812 all proved that this method is effective.
