随着地方工业的发展,需要连续作业的大设备容量不断增加,大容量动力装置启动及运行次数频繁,是造成电网运行不稳定的主要原因。当负荷变化幅度及持续时间小于电网承受能力及电压、周率的变化低于国家规定的标准时,称为稳定运行。反之,当负荷的变化幅度及持续时间超过了电网承受能力,造成系统电压及周率大幅度波动甚至解列。因此研究小电网的稳定运行提高电网效
With the development of local industries, the large equipment capacity that needs to be continuously operated continuously increases. The large-capacity power plant starts up and runs frequently, which is the main reason causing unstable operation of the power grid. When the load range and duration of change is smaller than the grid capacity and voltage, the change of the weekly rate is lower than the national standard, it is called stable operation. On the other hand, when the magnitude and duration of the load change exceed the capacity of the grid, the system voltage and the weekly rate fluctuate greatly or even be eliminated. Therefore, the study of the stable operation of small power grid to improve grid efficiency
