Application research of HGIS power distribution equipment optimal layout based on 3D design

受到占地面积、运行条件等多种因素的影响,导致HGIS配电装置最佳布置方案设计难度加大,为此进行了基于三维设计的HGIS配电装置优化布置应用研究.从可靠性、运行维护、防污性能等方面分析HGIS配电装置特性,在此基础上分别构建雷电模型、输电杆塔与母线模型,以获取不同雷电流波形取值,并根据工程实际情况确定模型对应参数,以增强配电装置的抗雷击性能.以减少占地面积与提高运行安全性为目标,利用三维设计方法制定整体设计架构,并引入协同思想对配电装置间隔宽度、纵向尺寸进行设计,将其无功补偿装置按照“一字型”排列,完成空间优化布置.仿真实验表明,该方法能够有效减少占地面积,且雷电流峰值较小,能提高安全性.

Due to the influence of many factors,such as floor area and operating conditions,it is more difficult to design the optimal layout scheme of HGIS distribution equipment.Therefore,the application research on the optimal layout of HGIS distribution equipment based on 3D design is carried out.The characteristics of HGIS power distribution equipment are analyzed from the aspects of reliability,operation and maintenance,anti pollution performance,etc.On this basis,the lightning model,transmission tower and bus model are constructed respectively to obtain different values of lightning current waveform,and the corresponding parameters of the model are determined according to the actual situation of the project,so as to enhance the lightning resistance performance of the distribution device.In order to reduce the floor area and improve the operation safety,the overall design framework is established by using the three-dimensional design method,and the space optimization layout is completed by introducing the collaborative idea to design the interval width and longitudinal size of the distribution device,and the reactive power compensation device is arranged according to the"one word"arrangement.Simulation results show that the method can effectively reduce the floor area,and the lightning current peak value is small,which meets the security requirements.
