摘要
根据斯特林发动机和异步发电机的特点,采用串联结构的异步发电模式,通过三相PWM全桥变换器解决了离网型斯特林发电系统的起动和发电问题,实现起动/发电双功能,使功率双向流动。系统电机控制采用带端电压补偿的V/f控制策略,对蓄电池采用DC-DC桥臂进行独立控制,稳态时保持蓄电池缓慢充电,在负载突变时,蓄电池相应放出或吸收能量,缓冲发动机的能量调节过程。仿真和实际示范应用证明了本系统的正确性和可行性。
According to the characteristics of stirling engine and induction generator, a three-phase full-bridge converter was used to solve the generation problem of off-grid stirling power generation system by using cascade structure mode, which realizes power two-way flowing function. The generator control is V/f control with voltage compensation. The battery control is DC-DC control, which makes it charge slowly at the state of stable, and discharge or absorb power when the load changes. The simulation and experiment both verify the feasibility.
