摘要
大型抽水蓄能机组对于电力系统调峰、填谷起到十分重要的作用。目前抽水蓄能机组的启动普遍采用静止启动变频器（SFC）方式,静止变频启动方式的关键在于在0-50Hz的转速变化范围内,系统能否准确快速地检测到转子位置。采用无速度传感器的电气方法测量出转子位置角,通过空间矢量控制对无速度传感器的大功率同步电机变频启动的控制算法进行深入研究,并通过RTDS仿真系统验证本文提出的启动控制方案的正确性。
Large pumped storage staion takes an important role for regulating load smoothly.At present,the SFC start mode is usually used as the common start mode in the pumped storage station.Detecting the rotor positon accurately and quickly is the key problem of the static frequence start mode when the motor frequence is changed from 0 to 50 Hz.The speed sensorless control algorithms was proposed to dectect rotor position,the space vector control method used in the speed sensorless high-power synchronous motor was deeply researched,and verifies the correctness of this start control method through the RTDS simulation system.
