摘要
电池储能系统是发电站中的重要组成部分,它对电网的可靠性和稳定性具有重大影响。电池储能系统通过在晚上负荷低谷区给蓄电池充电来减少白天负荷峰值需求,从而提高效率和负载因数,并且短期内能够降低电力需求的增长速度。电池储能系统并入电网需要良好的逆变技术,给出电池储能系统逆变器的数学模型及SVPWM基本原理,提出SVPWM逆变控制算法,在MATLAB/Simulink环境下建立模型进行仿真证明此方法的可行性。最后,设计出基于TMS320F2407A DSP芯片的控制电路,通过实验验证此方法的有效性与优越性。
Battery energy storage system is an important component of power plant, which has a great effect on the reliability and stability of power grids. Battery energy storage system decreases the demand of electric power load peak in the day by charging it at night, which improves the efficiency and load factor. Moreover the system can cut down the growth rate of electric power demand in the short run. A mathematical model for inverter of battery energy storage system and the basic principle of SVPWM （space vector pulse width modulation） was presented, and also one control algorithm of SVPWM for inverter was proposed. Under the MATLAB/Simulink environment, the simulation experiment was conducted to prove the method feasible. In the end, a control circuit based on TMS320F2407A DSP chip was designed to realize the SVPWM control algorithm. Results verify that method designed is valid and superior.
