晋东南变电站1 000 kV配电装置设计

相对于500 kV配电装置，1 000 kV装置可听噪声、无线电干扰及静电感应等环境影响问题更为突出，且设备安装高度及设备重心更高，使抗震性能降低。因此，降低环境影响、提高抗震性能成为晋东南1 000 kV配电装置设计的关键问题。文章对主变压器的选型、GIS配电装置的最优布置型式、1 000 kV四分裂导线优化、高抗回路设备连接方式及高抗噪声的控制等主要问题进行了重点研究。

Design of 1000 kV Distribution Equipments for UHV Southeast Shanxi Substation

The environmental impacting problems caused by 1000kV power transmission equipments such as audible noise, radio interference and electrostatic induction are more serious than those caused by 500kV power transmission equipments; meanwhile, due to the higher height of gravity centers of 1000kV equipments, the aseismic property of these equipments deteriorates, thus decreasing the influence on environment and intensifying the aseismic property of 1000kV power transmission equipments configured in Southeast Shanxi substation become the key points in the design of them. The research results of principal problems related to the design of 1000kV power transmission equipments for Southeast Shanxi substation are given, they are: type selection of main transformer, optimal layout of 1000kV GIS, optimization of 4-bundled conductor, connecting mode of 1000kV equipments with high reactance and noise reduction of them.
