【摘要】 本文以90年代初东北电力系统的吉黑电网为例,在进行了大量计算的基础上,分析了该网500kV工程投运初期在安全稳定运行方面的几个特点与存在问题,并就其安全稳定控制方案做了探讨。由于吉黑电网在结构上的代表性,因而本文所述结论将对我国其它电网的安全稳定控制研究具有一定的参考价值。更多还原

【Abstract】 Some characteristics and problems of the transient stability of Ji-Hei electric power system with 500kV lines under operating conditions are analysed based on a great deal of digital simulation in this paper. The control scheme of the system is also discussed. The obtained conclusions in this paper can be used for the engineer analysing other systems as a reference because of the typical feature of the structure of Ji-Hei electric power system.更多还原
