超导储能系统提高风电场暂态稳定性研究

摘要

The superconducting magnetic energy storage (SMES) system to enhance transient stability of wind farm was studied. Based on SMES principles, the SMES model had been built and control strategies had been designed for active power and reactive power decoupling control. The active and reactive power combination control strategy had also been propound.The calculate simulation was carried on by power system simulation software PSCAD/EMTDC.The results show that the active and reactive power can be compensated by SMES during the wind speed fluctuation and SMES also can enhance the transient stability of power system.%应用超导储能系统(SMES)对提高风电场的暂态稳定性进行了研究.在深入研究超导储能系统运行原理的基础上,建立了基于电压型换流器(VSC)的超导储能系统模型,实现了有功功率和无功功率的解耦控制,并提出了有功、无功功率综合控制策略.利用PSCAD/EMTDC软件进行了仿真计算,结果说明超导储能系统不但能够在风速波动时平滑风电场的功率输出,而且能够提高风电系统的暂态稳定性.
