I摘 要本文提出了有关南宁 110kv 变电站设计的相关方案。电力网络是电能传输的载体，变电站作为电力网络中的变电环节最重要的组成部分，它的稳定运行与否直接影响到电力系统的运行效率。南宁是广西的首府，是广西发展最为迅速的城市，城市内的负荷密度也随之迅速提高，增建新的变电站以减少每个变电站的供电半径能有效提高用户的用电质量。所以针对特定区域的 110kV 变电站方案设计具有实际意义。该设计通过分析变电站的原始数据，并通过对该方案的可靠性，灵活性和经济性分析和相应的负荷分析计算，确定可选择的电气主接线方案，为设计的 110 千伏变电站确定电气主接线方案。根据短路电流计算，选择 110kv 变电站的主要设备，主要设备通过电气设备的短路稳定性和热稳定性验证。最后，为该 110kV 变电站的防雷和继电保护配置提高了方案。关键词:电气主接线 负荷分析 短路电流计算 保护配置IIAbstractIn this paper, the design scheme of Nanning 110 kV substation is presented. Power network is the carrier of power transmission. Substation is the most important part of power network, and whether its stable operate or not directly affects the operation efficiency of power system. Nanning is the capital of Guangxi and the fastest-growing city in Guangxi. The load density in the city also increases rapidly. Adding new substations to reduce the power supply radius of each substation can effectively improve the quality of power consumption of users. Therefore, the scheme design of 110kV substation for a specific area has practical significance. Through the analysis of the original data of the substation, and through the reliability, flexibility and economy analysis of the scheme and the corresponding load analysis and calculation, the main electrical wiring scheme for the 110 KV substation is determined. According to the calculation of short-circuit current, the main equipment of 110 kV substation is selected. The main equipment is verified by short-circuit stabi...
