摘要
提出了基于P-V曲线的风电场接入系统稳态分析方法以及两个风电场同时接入系统的分析方法,该方法能够提供电压偏移量、电压波动范围等信息。文章还分析了风电场接入系统的电压要求及风电场运行对区域电网网损的影响,由仿真结果可见,风电场接入系统的最低电压应高于系统检修时的最低电压,而且风电场的接入有利于减少系统的网损。
A P-V curve based static analysis method for integration of wind farm into power system and a P-V curve based analysis method for the integration of two wind farms simultaneously into the same local power network are presented. In this method the information, such as voltage deviation, range of voltage fluctuation and so on, is provided. The voltage requirement for integrating a wind farm into the local power network and the influence of wind farm operation on the local power network loss are analyzed. The simulation results show that the lowest voltage for integrating a wind farm into the local power network should be higher than that of the power system in maintenance and the integration of wind farm is advantageous to reduce the loss of power network.
