摘要
目前抽水蓄能机组和燃气轮机组一般采用静止变频起动方式。在静止变频起动的低频阶段,机端电压很小且畸变严重的情况,针对这一情况,研究了一种基于机组起动恒加速度的开环控制方法。在理论分析的基础上进行了PSCAD和RTDS仿真,并在动模实验平台上进行了动模实验,证明了该方法在理论上是正确的,在工程上是可行的。
At present, static frequency converter is usually used for pump/motor and gas turbine starting. The synchronous machine＇s voltage is small and distorted seriously in the low frequency period, an open loop control method based on constant acceleration is put forward. PSCAD and RTDS simulation verification test and dynamic simulation experiment has been done based on the theoretical analysis, which verified the theoretical correctness and the engineering feasibility of the method.
