蒙古国塔木察格油田配电网结构优化与展望
|
摘要
蒙古国塔木察格油田配电网是以塔一联变电所为中心呈辐射形态的长线路,故障及检修时停电范围大、末端供电质量低,并且抵御自然灾害、外力破坏的能力较弱。通过安装电容器、避雷器、真空断路器等技术手段,对网架结构进行优化升级和系统改造,实现选择性限电及后备电源,提高了重要负荷供电可靠性;小范围线路检修或故障排查,减少了作业区大面积停电、停井的现象;接地装置的改进、线路防护工作的开展,增强了线路抵御自然灾害的能力;线路末端电压补偿,提高了配电网的供电质量。
The distribution network in Tamchag Oilfield of Mongolia Republic is a long radial line,taking Ta-1 Multi-purpose Substation as its central. The power failure and overhaul of the long line cause large scope of power cut,the supply quality of its end is low,and its ability to resist natural disasters and external forces is weak. By installing capacitors, lightning rods, vacuum circuit breakers and other technical means, the structure of the net structure is optimized and upgraded. The system transformation realizes the selective power limiting and backup power supply, improves the reliability of power supply for important loads. The small scale of line maintenance or fault detection reduces the phenomenon of large-scale power cut and well shutdown in the operation area. The improvement of grounding devices and development of line protection work enhance the line's ability to withstand natural disasters. The line terminal voltage compensation improves the power supply quality of the distribution network.
