| 中文摘要 | 借助电力储能装置,将常规电力系统中的同步发电机数学模型应用到新能源发电逆变器控制算法中,形成虚拟同步发电机(Virtual Synchronous Generator,VSG)。设计了原动机调节和励磁调节,并模拟同步发电机的转动惯量,使新能源电站对外接口具有频率和电压幅值下垂特性,解决了传统微电网逆变器在运行时输出阻抗小、阻尼小等问题,提高了稳定性。仿真和实验结果表明,设计的虚拟同步发电机能够模拟实际同步发电机的特性。; With the help of energy storage, synchronous generator model used in conventional power system being applied in renewable energy generation is called virtual synchronous generator(VSG) and presented in this paper. Through designing prime motor controller and excitation controller, renewable energy station with VSG can obtain the well-known frequency and voltage drooping mechanisms, and mimics a characteristic of system dynamic performance influenced by rotor inertia. It can solve the problems of low output impedance and low damp on conventional power converter, and improve the stability of renewable power generation system. The simulation and experimental results show that the proposed VSG algorithm is suitable to micro grid.(The simulation and experimental results show that the proposed VSG can simulate the characteristics of real synchronous generator.) |
