摘要
文中用实例阐述了工业企业自备电厂主变压器机端馈线发生三相和两相短路后暂态稳定的情况;以及电厂与外部系统非计划性解列后发电频率的变化情况。计算所用公式和所得结论,对类似发电厂电气部分的设计和运行有实际参考价值。
This paper presents a case study on the transient stability.When a three-phase or two phase short circuit happened on the main transformer or on the terminal feed line of the generator.The frequency characteristics of the plant when happened a suddenly disconnec- tion from the network is also discussed.The equations for calculation and the conclusion abtained can be used for the design and operation of the electrical part of the power plants of its kind.
