66 kV电网的网架优化方案研究

Optimal Scheme for 66 kV Power Grid Framework

针对电网双侧电源双T接线存在的问题,提出了将双侧电源链式接线作为66 kV电网新的目标网架型式.以长春地区66 kV电网网架为例,考虑到已建成电网的实际情况,提出了"∏-T"和"链-T"两种过渡方案,以缓解目前电网运行中的压力.所提方案具备良好的可实施性和经济性,在提高电网供电可靠性的同时,能显著提升网架供电能力,可供电网规划及发展作为参考.

In view of the problems existing in the double-T wiring of double-sided power supply of grid,a new target frame type of 66 kV power grid is proposed by using chain wiring of the bilateral power supply.Taking the 66kV power grid frame in Changchun as an example,and considering the actual situation of the established power grid,this paper puts forward the "ⅡT" and "chain 7I" as two kinds of transitional scheme,to alleviate the pressure in the current power grid operation.The proposed scheme,with good feasibility and economy,can significantly improve the power supply capacity of the grid frame while improving the grid power supply reliability ,providing a reference for the grid planning and development.
