摘要
虚拟同步电机分布式电源转子的控制性能过差会影响电力系统的供电效率,为了提升电力系统的供电效率,降低电流电压差异性变化导致虚拟同步电机运转停滞的突发可能性,提出虚拟同步电机分布式电源转子自适应控制方法。该方法通过虚拟同步电机的工作原理获取与分布式电源转子控制相关的因素并进行分析,同时将传输信号与VSM信号控制模型结合,实现虚拟同步电机分布式电源转子的自适应控制。最后以分布式电源转子作为试验对象,通过观察虚拟同步电机输出功率限额大幅度跳跃时,三种不同方法对与分布式电源转子动能相关的两项传输信号的控制结果,判断不同方法对虚拟同步电机分布式电源转子的控制能力。实验证明,该方法对分布式电源转子的输出功率限额和电流控制结果优于传统的控制方式。
The poor control performance of the virtual synchronous motor distributed generator rotor will affect the power supply efficiency of the power system.In order to improve the power supply efficiency of the power system and reduce the sudden possibility of the virtual synchronous motor running stagnation caused by the variation of current and voltage,a virtual synchronous motor distributed generator rotor adaptive control method is proposed.This method obtains and analyzes the factors related to distributed power supply rotor control through the working principle of virtual synchronous motor.At the same time,it combines the transmission signal with VSM signal control model to realize the adaptive control of virtual synchronous motor distributed power supply rotor.Finally,taking the distributed generator rotor as the test object,by observing the control results of three different methods on the two transmission signals related to the kinetic energy of the distributed generator rotor when the output power limit of the virtual synchronous motor jumps greatly,the control ability of different methods on the distributed generator rotor of the virtual synchronous motor is judged.The experimental results show that this method is superior to the traditional control method for the output power limit and current control of the rotor of the distributed power supply.
