针对新能源能量随机波动的缺点及传统整流方式的不足,克服传统的晶闸管相控整流器存在功率因数低、谐波大等缺陷,提出了基于DSP的新能源可控整流与控制系统的设计。通过分析比较采用空间矢量脉宽调制(SVPWM)的控制策略,以TMS320F28027数字信号处理器为控制核心,对可控整流和控制系统的硬件系统和软件系统进行了设计,实现了三相PWM整流器的电流解耦控制;最后通过仿真及实验平台进行了仿真实验,验证了系统方案的可行性。
In view of the shortcomings of stochastic fluctuation of new energy sources and the shortcomings of traditional rectification methods, overcoming the defects of traditional thyristor phase-controlled rectifiers such as low power factor and large harmonics, a new controllable rectification and control system based on DSP is proposed. By analyzing and comparing the control strategy of space vector pulse width modulation (SVPWM) and taking TMS320F28027 digital signal processor as the control core, the hardware system and software system of controllable rectifier and control system are designed, and the three-phase PWM rectifier Current decoupling control. Finally, the simulation experiment is carried out by simulation and experimental platform to verify the feasibility of the system scheme.
