摘要
宁夏-山东直流联网工程额定输电功率4000MW,该工程使华北、西北两大电网直接相连,这样一个容量巨大、结构复杂的交直流混合电网,其背景谐波问题不仅是换流站交流滤波器研究设计中必须重点考虑的问题,也是系统中其它主设备研究设计中必须慎重对待的问题。因此,研究宁夏电网背景谐波及进行银川东换流变电站交流背景谐波潮流计算具有重要意义,本文重点论述了银川东换流变电站交流330kV侧的背景谐波概况。
The rated transmitted power of Ningxia to Shandong DC connected network project is 4 000 MW. The project directly connects North Grid and Northwest Grid of China, which is AC/DC mixed grid with large capacity and complex structure, its background harmonic is considered not only in the study of AC filter at converting substation, but also the design of other main equipment in the power system. So it's significant to study background harmonic in Ningxia Grid and AC background harmonic tide calculation in Yinchuan Eastern Converting Substation. The paper focuses on the background harmonic outline of AC 330 kV side in Yinchuan Eastern Converting Substation.
