摘要

在MPPT模式下，永磁直驱风力发电机很难正确响应电网频率的变化。大型风力发电机并网后，将增加电力系统的调频压力。传统的变频调速系统通过降低风力发电机的发电效率，保留一部分有功功率用于调频，但也存在频率范围小、俯仰角调整频繁等问题。因此，本文提出了一种基于混合储能直流接入单台风力发电机辅助电网频率支持的控制方法，并设计了一套电池与超级电容器优势互补的储能设备与风力发电机，以响应电网调频调节的风力发电系统。

Research on Supporting Control Technology of Wind driven generator Auxiliary Power Grid Based on Energy Storage DC Access

Under MPPT mode, It is very difficult for permanent magnet direct drive wind driven generator to respond correctly to changes in the frequency of the grid. Large-scale wind driven generators connected to the power grid will increase the frequency regulation pressure of the power system. The traditional frequency control system reserves a part of active power for frequency regulation by reducing the generating efficiency of wind driven generator, but there are also some problems such as small frequency range and frequent adjustment of pitch Angle. Therefore, this paper proposes a control method based on hybrid energy storage DC access to single wind driven generator auxiliary power grid frequency support, and designed a set of energy storage equipment and wind driven generator with complementary advantages of battery and super capacitor to respond to the power grid FM regulation wind power generation system.
