20kV电压等级在油田电网中的应用探讨

目前油田用电负荷普遍具有负荷分散、负荷滚动建设、负荷中心偏移、大部分配电变压器负荷率偏低等特点,同时油田电网的建设通常根据油田勘探开发进程同步滚动建设,往往造成不断增容扩建或供配电建设投资浪费的现象。鉴于此,探讨了在油田电网逐步推广20kV配电电压必要性、可行性和实施方案,认为应用20kV配电电压可提高油田中压配电网的输送能力,增大供电半径,降低线路电压损失和功率损耗。

Application of 20kV Distribution Voltage in Olifield Power Grids

The power use in Chinese oilfields is typically characterized by scattered load,the rolling construction of power generating capacity,load center shift and low load of most distribution transformers.In addition ,Chinese oilfields usually add power grids as oilfield exploration and development proceeds ,often resulting in a continuous expansion of power supply and distribution capacity and haphazard investment.This article discusses the necessity,feasibility and options of introducing 20kV distribution voltage in oilfields and concludes that the application of 20kV distribution voltage in oilfields can enhance the capacity of medium-voltage distribution networks in the oilfields,increase the power supply radius and reduce voltage and power loss for power lines.
