| 摘要: |
| 对双馈风力发电机网侧变流器进行了建模，提出了网侧变流器降阶的端口受控耗散哈密顿（PCHD）模型。针对网侧变流器存在的非线性，在其降阶PCHD模型的基础上设计了相应的系统互联与阻尼分配无源性（IDA-PB）控制算法，并进一步提出了能量成型阻尼注入的无源性控制改进策略。通过对所提出的控制策略进行仿真分析和实验验证，表明网侧变流器交流侧能够得到更好的电流特性，减少了变流器到达稳定所需的时间并改善了动态特性，从而提高了系统的稳定性和稳态精度。 |

| Abstract: |
| The model of grid-side converter in doubly-fed wind generation system is built and an order-reduced PCHD（Port-Controlled Hamiltonian with Dissipation） system is proposed，based on which，the corresponding IDA-PB（Interconnection and Damping Assignment-Passivity Based） control method is designed according to its nonlinearity and an improved control strategy of energy-shaping and damp injecting is further proposed. Simulative and experimental results show that，AC-side current characteristics of grid-side converter are enhanced，the time needed for stabilizing the converter current is decreased and its dynamic performance is improved，resulting in better system stability and steady-state precision. |
