摘要
风电作为最具发展前景的新能源发电方式,其大规模开发及利用已成为必然趋势.规划风电场时,在满足风资源利用率、地理条件、电网约束等条件下,以有效降低网损为目的选择合理的风电场功率汇集方式将会带来巨大的经济效益.本文从风电场接入系统的电压等级入手,在理论分析风电场功率汇集方式的基础上,以冀北张家口地区接入康保500kV 的风电场为例,讨论考虑网损最优的风电场功率汇集方式.
As the most development prospect new energy power generation mode, the large-scale development and utilization of the windpower has become an inevitable trend. When planning a wind farm, under the condition of obey the constraints such as windresource utilization, geographical conditions, and power constraints etc., choosing reasonable collection modes of wind power inthe purpose of reducing the network loss will bring huge economic benefits. This paper starting from the accessing voltage level ofwind farm, basing on theoretical analysis of wind farm power collection modes, illustrating of the wind electric fields accessingKang Bao 500kV collection station in Jibei, discuss the wind power collection modes considering the optimal of network loss.
