| 摘 要： | 电力系统中部分重要用户负荷包含较多敏感负荷，这类用户在特殊时期对电压质量的要求非常高。以某重要用户（以下简称HXS）为例，从保障可靠供电的角度出发，采用电力系统计算机辅助设计一直流系统电磁暂态仿真软件（powersystemcomputeraideddesign-electromagnetictransientinDCsystem，PSCAD／EMTDC）建立了HXS的输配电系统模型，分析HXS的供电方案与负荷组成情况。针对系统中不同地点、不同类型、不同持续时间的故障对用户节点电压暂降造成的影响及影响程度进行仿真分析，并从供电部门的角度提出了有针对性的电压暂降控制措施。

| Abstract: | There is more sensitive load in some important users in power system and these users have strictly requirements on voltage quality during special period.One important user(hereinafter referred to as HXS) is taken for instance to establish a transmission & distribution system model by means of EMTDC/PSCAD from the perspective of power supply reliability so as to analyze power supply scheme of HXS and load composition.Influence of faults of different locations,types and durability time on node voltage sag and influence degree are simulated and analyzed.Besides,countermeasures against voltage sag are presented in respect of power supply. |
