摘要
随着糯扎渡直流与阳江核电的投产,500k V江门变电站的500k V出线增加,江门站的GIS设备将无法满足系统对母线穿越功率与短路电流水平的要求。为解决这一问题,对几种可行措施的实施难度、改造效果以及对系统稳定性的影响等进行了分析。综合考虑,推荐对江门站进行原地改造,将500k V配电装置改造为HGIS设备。
With commissioning of Nuozhadu DC project, Yangjiang nuclear power station and increase in outgoing line of 500kV jiangmen substation, GIS equipment ofjiangmen substation will not be able to match bus crossing power and short circuit current of the system. To solve the problem, this paper analyses difficulty, effect and impact on the system of several possible measures. Then, jiangmen substation reconstruction is suggested. Comparing technicality, economy of two possible scheme and calculating short circuit current, the recommendatory scheme is jiangmen substation reconstruction in original area： 500kV distribution device is modified to HGIS.
