新建风电场接入电网需要考虑接入系统的网架结构、潮流分布、对电能质量的影响,并结合经济性、技术实现难度以及接入后系统的稳定性等方面选出最佳接入方案。文章以新疆某风电场为例,结合接入系统的网架结构,提出了不同接人方案,通过计算分析确定了最佳接入方案,并对风电接入后系统的暂态稳定特性进行校验。
The best program of a new wind farm that connects to grid should take some factors into con- sideration, including the grid structure of connected system, an influences of wind power connecting to grid on power flow distribution, effects on the quality of electric power, economical efficiency, difficulty of technical realization, and the stability of connected system. Taking an example of a wind farms in Xinjiang, different connecting solutions are put forward according to space truss structure, and the best connecting solution is determined after calculations and analyses, finally the system transient stability characteristics are checked after wind power connected.
