针对动力涡轮发电机组并网运行的需求,开展变速恒频装置的系统总体设计、关键部件选型、自动功率匹配控制策略设计,并完成Simulink仿真分析与试验验证。分析结果表明:变速恒频技术在船舶动力涡轮发电机组中的应用可以达到降低动力涡轮发电机组的控制难度、提升发电品质的目的;在自动功率匹配控制策略下,变速恒频装置注入电网功率可自动跟随输入发电机机械功率的变化而变化,实现输入、输出功率的自动平衡。

To meet the requirements of grid connected operation of power turbine generator units,the overall system design,key component selection and automatic power matching control strategy design of variable speed constant frequency(VSCF) device were carried out,and Simulink simulation analysis and experimental verification were completed. The analysis results show that the application of VSCF technology in marine power turbine generator set can reduce the control difficulty of power turbine generator set and improve the power generation quality;Under the automatic power matching control strategy,the power injected into the grid by the VSCF device can automatically change with the change of the mechanical power of the input generator to achieve the automatic balance of the input and output power.
