摘要
一次故障信息建模是电网继电保护故障信息系统的基础。首先提出一次故障信息模型,该模型由电网、变电站、间隔、IED等4层组成,IED的一次故障信息模型是其基础。并对模型的关联和参数,结合继电保护装置和故障录波器的信息输出特点,提出了具体的识别方法。该方法已在浙江省电网继电保护故障信息系统进行了应用。
As the basis of the grid relay protection and information system, the primary fault information modeling is put forward first, which consists of four hierarchical levels, the grid, substation, bay, and IED, with the IED level fault information model as the foundation. As for its parameter setting and correlation, by taking into account the relay protection and recording device's information output characteristics, the specific identifying method is proposed, which is applied in the power system of Zhejiang Province.
