摘要
电力电子接口安装在源、网、荷的深度应用使得电力系统的电力电子化进程不断推进,传统电力系统频率控制方法中并未考虑电力电子接口对其控制的影响使得频率偏差较大,对此,开展考虑电力电子接口的电力系统频率控制方法研究。首先确定电力电子接口电源频率控制范围,再对电力系统等效惯量与调差系数进行计算,最后通过多同步电网间频率支援,实现对电力系统频率控制。通过实验证明,该控制方法与传统控制方法相比可有效降低频率偏差,实现电力系统频率的高精度控制。
The in-depth application of the power electronic interface installed in the source,network,and charge makes the power electronic process of the power system continue to advance.The traditional power system frequency control method does not consider the influence of the power electronic interface on its control,which causes a large frequency deviation.To conduct research on power system frequency control methods considering power electronic interfaces.First determine the frequency control range of the power supply of the power electronic interface,then calculate the equivalent inertia of the power system and the adjustment coefficient,and finally realize the frequency control of the power system through multi-synchronization frequency support between the power grids.Experiments show that the control method can effectively reduce the frequency deviation compared with the traditional control method,and achieve high-precision control of the power system frequency.
