| 摘 要： | 针对传统微型燃气轮机(简称微燃机)发电系统微电网运行时存在的冲击性负载问题,从其工作机理角度分析,发现根源在于微燃机输出功率调节响应较慢。为了弥补微燃机输出瞬时功率的不足,提出了冲击补偿的瞬时功率快速控制方法。通过微燃机发电机组自身功率响应预测进行瞬时补偿功率控制,基于超级电容储能单元的高功率动态响应弥补微燃机输出功率动态响应低的问题,使系统实时处于瞬时功率平衡状态,保证直流母线电压的平稳,增强微燃机发电系统对冲击性负载的适应能力。最后在实验平台上对所提控制策略的正确性和可行性进行了验证。

| Abstract: | Based on the analysis of its working mechanism, it is found that the impact load of traditional micro-turbine power generation system during its operation in microgrid is due to the slow response of its micro-turbine output power regulation, aiming at which, a strategy of quick instantaneous power control based on the impact compensation is proposed to make up for the instantaneous output power shortage of micro-turbine. The instantaneous compensation power control is based on the power response prediction of micro-turbine generator set while the quick dynamic power response is based on the super-capacitor energy storage to compensate the slow dynamic power response of micro-turbine output power, which balances the system instantaneous power in real time to ensure the stable DC bus voltage and enhance the adaptability of micro-turbine power generation system for the impact load. The correctness and feasibility of the proposed control strategy are verified by experiments. |
