摘　　要：针对传统的燃料电池并网控制系统普遍存在的动态响应不快的问题,重点研究了并网控制系统的拓扑结构和控制策略,提出了DC/DC变换器和DC/AC逆变器的设计思路,重点分析了有功和无功功率解耦滞环控制策略的设计方法,并给出了实现方案。基于Matlab/Simulink仿真环境建立了6kW燃料电池并网系统模型,对系统拓扑结构和控制方法进行了验证,证明了文中方法的正确性和有效性。Traditional control system to connect fuel cells with the power grid has the disadvantage of slow dynamic response, for this reason special attention are paid to the research on topological structure and control strategy of the control system to connect fuel cells with power grid. The design idea for DC/DC converter and DC/AC inverter is proposed. The design method of decoupling hysteresis control strategy for active and reactive power is emphatically analyzed and its implementation scheme is given. In the simulation environment of Matlab/Simulink a grid-connected model for fuel cells with capacity of 6kW is built to validate the systemic topological structure and control method. Simulation results show that the proposed approach is correct and effective.
