摘要
对采用不同控制策略的风电场接入系统进行稳态分析,将风电场输出功率随风速变化的间歇性和波动性扰动对所接入地区电网的影响离散化为多个稳态潮流计算,并通过绘制不同控制策略下风电场公共接入点、地区电网电压中枢点、重要变电站的PV曲线、网损曲线,分析风电场接入后地区电网的电压及网损变化,最后对采用不同控制策略的风电场最大接入容量进行分析。
The steady-state analysis on switching-in system for wind farm adopting different control strategies is conducted. The impacts of intermittence and fluctuating disturbance of wind farm output power varying with wind speed on the regional power grid to be connected with are discretized into steady-state power flow calculations; by means of plotting the PV curves and network loss curves of common connecting point of wind farms, the voltage pilot node of regional power grid and important substations, the variations of voltage and network loss after the switching-in of wind farm are analyzed. Finally, the maximum switching-in capacity of wind farm adopting different control strategies is analyzed.
