海上平台能源路由器母线电压控制策略研究

Study on Bus Voltage Control Strategy for Energy Routers on Offshore Platforms

适用于海上平台能源路由器直流母线电压稳定性控制方法目前还不够完善,为了解决海上平台脉冲负载对能源路由器直流母线电压造成严重冲击的问题,引入混合储能系统,提出一种考虑电压波动系数的双向DC/DC变换器功率预测控制策略及考虑混合储能能量限值的功率管理方法.经过仿真,系统的直流母线电压动态响应达到预期需求.搭建海上平台能源路由器实验平台,通过实验验证了该方案具有较高的动态响应及稳定性.

The DC bus voltage stability control method for energy routers on offshore platforms is still not perfect.In order to solve the problem that the DC bus voltage of energy routers is severely impacted by pulse loads on offshore platforms,a hybrid energy storage system is introduced and a bi-directional DC/DC converter power predictive control strategy considering the voltage fluctuation coefficient and a power management method considering the energy limit of hybrid energy storage are proposed.After simulation,the dynamic response of the DC bus voltage of the system meets the expected requirements.An experimental platform of the energy routers on offshore platforms is built,and the high dynamic response and stability of the scheme are verified through the experiment.
