| 摘 要： | 基于机组间相对运动的暂态能量评估系统暂态稳定性的观点，提出了等效机暂态能量函数法，该方法可以由临界机相对于参考机摇摆曲线定性判别系统暂态稳定性并给出稳定裕度，仿真计算验证了等效机暂态能量函数法的有效性，表明该方法可应用于在线暂态稳定评估。

| Abstract: | Method of Equivalent Machine Transient Energy Function was proposed based on the idea that system stability could be assessed by transient energy reflected by relative moving of machines. Whether the system was stable or not can be determined by using this method and the transient energy margin of the system could be given. Simulation results illustrated the validity of the method and suggested the possibility of assessment of onlinetransient stability. |
