摘　　要：为了维持配电网并网逆变器的稳压运行状态,实现对并网环境中电信号输出功率的有效控制,研究面向新能源消纳的配电网GTI电压控制方法。构建异步感应发电机闭环和GTI闭环数学模型,实现对主要控制器闭环的建模处理。按照新能源消纳原理,分析GTI的配电特性,通过计算GTI电压负荷指标,对配电网并网电压进行调峰处理,联合各类闭环回路结构,完成面向新能源消纳的配电网GTI电压控制方法。实验结果表明,配电网GTI运行电压能够长时间稳定在200~240 V的数值范围之内,可以较好维持配电网GTI的稳压运行状态,实现对并网环境中电信号输出功率的有效控制。In order to maintain the stable operation state of the grid connected inverter in the distribution network and achieve effective control of the electrical signal output power in the grid connected environment,a new energy consumption oriented distribution network GTI voltage control method is studied.Construct mathematical models for asynchronous induction generator closed-loop and GTI closedloop,and achieve modeling and processing of the main controller closed-loop.According to the principle of new energy consumption,analyze the distribution characteristics of GTI,calculate the voltage load index of GTI,perform peak shaving on the grid connected voltage of the distribution network,and combine various closed-loop loop structures to complete the distribution network GTI voltage control method for new energy consumption.The experimental results show that the operating voltage of the distribution network GTI can be stable within the numerical range of 200-240 V for a long time,which can better maintain the stable operating state of the distribution network GTI,and achieve effective control of the electrical signal output power in the grid connection environment.
