摘　　要：燃料电池电站功率调节系统对整个电站系统工作的可靠性、效率和输出波形质量有很重要的影响.文中通过仿真、实验的方式,研究电路结构与燃料电池参数的优化配合关系,提出了高效逆变主电路的设计规律.通过研究逆变系统的数学模型,为逆变系统输出波形控制技术提供理论依据和指导,并研制了实用的、高性能和低成本的数字化、智能化控制系统,其中着重于数字控制系统的逆变器输出波形控制技术.文中还采用滑模变结构控制策略研究了波形控制技术,并通过实验进行了验证.结果表明,文中所提出的设计方案满足了系统功能要求,并具有良好的可靠性、输出波形质量和较高的转换效率.The power conditioning system of a fuel cell power plant is very important to the reliability and efficiency of the power plant system as well as to the quality of the output waveform. In this paper, the optimized cooperation between the main circuit structure of the power conditioner and the fuel cell parameters is investigated by simulation and experiment, and the law of designing efficient main circuit for the power conditioning system is proposed. By investigating the mathematical model of the inverter system, some guidance is provided for the inverter output waveform control. A digital intelligent control system with good practicability, high performance and low cost is then designed, in which the output waveform control is emphasized. Moreover, the waveform control scheme based on the sliding-mode control policy is investigated, and is then testified by experiments. It is found that the proposed system satisfies the requirements of the power plant, and possesses good reliability, high output waveform quality and great efficiency.
