基于FPGA+AVR单片机的SVG结合TSC的研究

SVG with TSC based on FPGA and AVR microcontroller

提出了通过控制晶闸管投切电容器(TSC)来减小SVG从电网吸收的电流幅值,从而减少补偿量的基本理论,并给出了此种无功补偿系统的控制方法。针对SVG对高效率的需求,硬件采用FPGA和AVR单片机相结合的方法,AVR单片机自带的各种设备降低了硬件结构的消耗,2种控制硬件的结合提高了无功补偿的运算速度。通过Simulink搭建的仿真电路验证了此方法的可行性。

Controlling the thyristor switch capacitor was proposed to reduce the current which drawn from the grid by SVG,reducing the amount of compensation,and there is such a control system of reactive power compensation.As SVG demands high efficiency,hardware is the combination of FPGA and AVR microcontroller,the devices on AVR microcontroller itself reduce the hardware structure,and the combination of the two controlling hardwares improves the speed of compensator.The circuit of simulation built by Simulink proves the feasibility of this experiment.
