本文的目的是介绍通过中小企业系统连接风电场的概念。在这项工作中，SMES系统被应用于一个风电场，该风电场通过背靠背直流链路与电网互联，以实现风力发电机组的变速运行。该系统能够根据电力需求实现风电场的输出功率均衡，并可以通过选择SMES的最佳放电/充电率来降低变流系统的容量。通过利用SMES的储能，该系统还可以补偿叶片的惯性，从而可以根据风况快速控制风力发电机组的转速。介绍了风电场输出功率均衡SMES的设计条件，并对100 MW级风电场SMES的配置进行了探讨。
The objective of this paper is to introduce the concept of wind farms linked by SMES systems. In this work, the SMES system is applied to a wind farm that is interconnected with a grid through a back-to-back DC link for the variable speed operation of the wind turbines. This system enables the output power leveling of the wind farm depending on the power demand and can reduce the capacity of the converter system by selecting an optimal discharge/charge rate of the SMES. By using the stored energy of the SMES, this system can also compensate the inertia of the blades so that the wind turbine speed can be rapidly controlled depending on the wind condition. This paper describes the design condition of the SMES for the output power leveling of the wind farm and discusses the SMES configuration for a 100-MW class wind farm.
