摘要
为了确定给定电网允许接入的风电场最大装机容量,提出应用稳态分析和暂态校验相结合的方法。在稳态分析中对风电场的处理采用根据风速确定有功,根据有功和节点电压初值确定无功的方法,能够准确反映风电机组的无功电压特性;在暂态校验中考虑了阵风、渐变风及系统故障方式的影响,确定能使系统保持暂态稳定的风电场容量;对实际电力系统的仿真计算结果表明,利用所提方法确定的风电场最大接入电力系统容量,可以保证风电场自身及系统运行的稳定性。
In order to determine the maximum installed capacity of wind power integration into certain power grid, a computing method that applying steady analysis and transient check computation is presented. The processing of wind farm node is to compute the active power according to the given wind speed, then to compute the reactive power according to the active power and voltage initial value, which reflects its reactive power-voltage character accurately in steady analysis, the disturbance of gust, graded wind and system-down are all considered in transient check computation to determine the wind power plant capacity. According to the simulation results of an actual power system, the maximum capacity of wind power integration into power system that calculated using the above method can ensure ＇the stability of power grid and the stability of wind farm itself.
