摘　　要：电力电子元件、非线性负荷、分布式电源等大量接入电网,带来巨大经济效益的同时对电网的电能质量也产生了较大影响,所以有必要在这类负荷并网运行之前对其可能给配电网电能质量造成的影响进行预估。为此,在MATLAB/Simulink中搭建配电网基本模型以及暂态电能质量干扰源模型,完成对谐波、三相不平衡、电压暂降(暂升)、电压波动的仿真,并且利用GUIDE设计用于配电网暂态电能质量仿真的人机交互界面,方便使用者对线路结构参数,暂态电能质量事件的类型及其发生的位置、程度和时间进行自定义设置。最后利用此系统以九节点系统图为例进行仿真试验,仿真试验结果验证了此仿真系统的可行性。A large number of power electronic components, nonlinear loads, distributed power sources, etc. are connected to the grid, which not only brings huge economic benefits, but also has a great impact on the power quality of the grid. Therefore, it is necessary to estimate the possible impact of such loads on the power quality of the distribution network before they are connected to the grid. To this end, the basic model of the distribution network and the transient power quality disturbance source model are built in MATLAB/Simulink to complete the simulation of harmonics, three-phase unbalance, voltage sag(swell), and voltage fluctuations. Moreover, GUIDE is used to design the human-computer interaction interface for transient power quality simulation of distribution network, which is convenient for users to customize the line structure parameters, the types of transient power quality events and the location, degree and time of occurrence. Finally, the simulation test is carried out using the system with the nine-node system diagram as an example, and the simulation test results verify the feasibility of the simulation system.
