摘要
为了保证黑启动试验方案的切实可行,必须要对初选的黑启动方案进行仿真校核研究。黑启动过程中有可能发生的发电机自励磁问题是决定黑启动方案是否可行的关键因素之一,因此首先研究介绍了黑启动中产生自励磁的原理和常规的判定方法,而后建立了各个元件基于PSCAD/EMTDC的自励磁仿真模型,并结合黑启动方案实例进行了仿真,仿真结果验证了方案的有效性,体现了该仿真方法的优越性。
It is very necessary to make simulation for the original black-start scheme. Whether the generator＇s self-excitation takes [dace during black start is a key factor for determining feasibility of the black-start schemes. So in this paper, some familiar criterions are given after the fundamental of generator＇self-excitation is introduced and a simulation system based on PSCAD/EMTDC is designed. Then this method of simulation is used for a actual black-start scheme. The simulation waves of the typical example show that the scheme is effective, and the method is of advantage.
