摘要
为了较好地利用光伏并网新能源,防止在使用过程中的孤岛效应,提出了利用电力电子技术模拟传统的RLC负载的有效方案,并针对孤岛检测提出了一种基于重复控制器与复合控制器的新型电力电子孤岛检测装置,分析了控制系统设计流程,阐述了硬件电路设备的选定原则与方法。仿真结果表明,该装置能够满足检测新能源并网逆变器的防孤岛功能要求,并可以模拟电网的种种状态,节省了电能,提高了装置的利用率。
In order to make use of the photovoltaic grid connected new energy better and to prevent the islanding effect in the process of use,this paper proposed to use the power electronic technology to simulate the valid scheme of traditional RLC load.A new type of power electronic islanding detection device based on the repetition controller and recombination controller was proposed in allusion to the islanding detection.This paper analyzed the control system design flow and expounded the selected principle and method of the hardware circuit equipment.The simulation result shows that this device could meet the anti-islanding function requirement of detection new energy grid-connected inverter and simulate a variety of power grid state,so as to save the energy and to improve the use ratio of the device.
