【摘要】 冲击负荷模型是评估其对电力系统运行影响的关键。文中提出了一种在ATP／EMTP中应用的基于实测数据的冲击负荷实用建模方法。该方法建模简单,适用于各类冲击负荷,具有较好的推广能力,与实测数据的比较证明了该方法的准确性和有效性。同时,应用此建模方法为一实际电力系统中的冲击负荷建模,仿真并讨论了多个冲击负荷集结对电力系统的影响。计算结果表明,冲击负荷影响邻近发电机组的寿命,多个冲击负荷的作用需通过仿真确定。更多还原

【Abstract】 Models for the impact load play an extremely important role in assessing the influence of impact load on power system operation. A practical modeling method is proposed in which the impact load is expressed as a controlled current source based on field data. This method is easy to use and applicable to all kinds of impact load. It is proved by test results that this modeling method is both accurate and effective. The application of the method is implemented in an actual power system. The simulation results show that the operation of the impact load affects the useful life of nearby generator units and the effect of multiple impact loads should be determined by simulating.更多还原
