| 摘要: |
| 简要地介绍了广东韶关电网现状及存在电压较高的问题，根据电力系统有关规程要求并结合500kV韶关－－北郊输变电工程内过电压及绝缘配合研究，对500kV韶关输变电工程进行调相调压计算分析，在此基础上，提出了韶关500kV变电站1号主变低压侧不需装设容性无功补偿设备，但需装设135Mvar的电抗器组，主变采用载调压方式更有利于未来韶关电网电压调整及主变抽头应放于主变较低位置等建议，力求为该工程今后的安全运行提供参考。 |

| Abstract: |
| The present state of Shaoguan power network and its existing over voltage problems are briefly described.According to relevant regulations of electric power system and combined with the internal over voltage and insulation coordination study on 500 kV Shaoguan beijiao transmission project,the phase and voltage adjustment calculation and analysis for 500 kV Shaoguan transmission project are carried out.Based on it,the following suggestions are proposed.The compensative capacitor is not necessary at low voltage side of 500 kV Shaoguan substation #1 main transformer;a 135 Mvar reactor set is needed;the adjustable main transformer is preferred for future voltage adjustment of Shaoguan power network;and the taps should be set in lower position.These suggestions are useful for the safe operation of Shaoguan transmission project in future. |
