| 摘要: |
| 大容量储能发电机作为脉冲电源，整流后通过逆变器向大功率脉冲负载供电。采用储能发电机直流侧并联方式工作，可以有效提高系统带载能力与可靠性。当并联运行的储能发电机转速不同时，根据转速合理分配电机释放功率可以有效提高系统工作效能，因此需要设计一种具有功率调节功能的励磁控制算法。在电压、电流双闭环控制的基础上，引入功率前馈控制，推导并求解了前馈功率与励磁电流关系以及控制参数，并根据电机初始转速设计了功率分配算法。仿真试验结果表明，功率前馈控制在励磁控制过程中起主导作用，有效分配储能电机释放功率大小，提高了励磁电流响应速度，抑制了负载功率扰动对励磁控制系统的影响。 |

| Abstract: |
| High-capacity energy storage generator can work as pulse power supply for large pulse power load through inverter after the energy storage generator′s output rectified. The loaded ability and reliability of system can be improved effectively with energy storage generators working in parallel operation. Reasonably distributing the output power of energy storage generators working in parallel operation with different speed can effectively improve the performance of system. Therefore, it is necessary to design a kind of excitation control algorithm with power regulation function. The power feed-forward control was introduced on the basis of voltage and current closed-loop control, the relationship between load power and excitation current was deducted and the feed-forward control parameters were solved, and according to the energy storage generator initial speed, the load power distribution algorithm was designed. Simulation test results show that the power feed-forward control plays a leading role in excitation control, which can control the energy storage generator′s output power and increase the excitation current response speed, and can inhibit the disturbance of load power on excitation system effectively. |
