摘　　要：以微型燃气轮机发电系统为核心的冷、热、电联供系统是我国电力科学重点关注技术之一,研制出一套能适用于系统启动加速和发电运行的综合控制方案具有重要意义。本文提出了基于双向背靠背变流器的高速微型燃气轮机直驱发电系统结构,并研究了相应变流器的控制策略,电机侧变流器采用磁场定向的矢量控制,电网侧变流器采用基于直流母线电压的解耦控制。在Matlab/Simulink平台下搭建了微型燃气轮机发电系统仿真模型,仿真结果验证了控制策略的可行性。Nowadays,combined cooling,heating and power systems based on micro-turbine generation systems have been one of the key technologies in power systems in China.It is of great importance to develop a comprehensive control strategy of a high speed micro-turbine generation system,which is suitable for not only the start-up process but also the generation process.A structure of the direct-driven micro-turbine generation system is proposed based on a bidirectional back-to-back converter.The field oriented vector control is used for the machine-side converter in the start-up process,while the decoupling control strategy based on the direct voltage is used for the grid-side converter.A simulation model of micro-turbine generator system is built on the Matlab/Simulink platform.The control strategies have been verified by the simulation results.
