中文摘要：

为优化柴油发电机组（diesel generator,DG）的动态输出电能质量,将包含超级电容（super capacitor,SC）的储能型功率补偿系统（storage energy-power compensation system,SE-PCS）与DG相并联共同为负载供电。提出用于SE-PCS的基于e指数函数的动态参考有功功率生成方案。在负载突变时,由SE-PCS按照e指数函数短时输出有功功率以提高DG的动态输出性能。给出了e指数函数的初值、时间常数以及SC容值的设计原则。进一步分析了SC内阻对SC输出电压范围的影响,进而给出了新的保持SC输出电压范围不变的SC容值设计原则,以保持系统的安全可靠运行。相应的仿真结果证明了所提出的方案、控制策略及参数设计原则的正确性和有效性。

英文摘要：

To optimize the dynamic output power quality of the diesel generator （DG）, the storage energy-power compensation system （SE-PCS） containing super capacitor （SC） is connected with DG in parallel to supply power to load. A generation scheme of dynamic referential active power for SE-PCS, which is based on the exponential function with e as the base, is proposed. When sudden change of load occurs, SE-PCS outputs active power transitorily according to e-based exponential function to enhance the dynamic output performance of DG. The initial value and the time constant of e-based exponential function as well as the design principle of capacitor quantity of SC are given. Further, the impact of the inner resistance of SC on the output voltage range of SC is analyzed, and then a new design principle for the capacitor capacity of SC to keep the output voltage range of SC constant is put forward to maintain secure and reliable operation of SE-PCS. The correctness and effectiveness of the proposed scheme, control strategy and design principle of parameters are validated by corresponding simulation results.
