发布时间:2000-03-21 实施时间:


电力厂和变电站中的直流辅助装置是电力系统中重要的组成部分,它们为电力系统的正常运行提供了必要的支持和保障。然而,在电力系统中,短路事故是不可避免的,一旦发生短路事故,将会对电力系统和直流辅助装置造成严重的损害。因此,为了保证电力系统的安全运行,需要对直流辅助装置的短路电流进行计算和分析。

IEC 61660-1:1997/COR2:2000 标准规定了直流辅助装置短路电流的计算方法和公式。该标准要求在计算短路电流时,需要考虑直流电源的内阻、电缆的电阻、电感和电容等因素。同时,该标准还规定了计算中需要考虑的其他参数,如电源电压、电缆长度、截面积等。

该标准的主要内容包括以下几个方面:

1. 短路电流的计算方法和公式;
2. 直流电源内阻的计算方法;
3. 电缆电阻、电感和电容的计算方法;
4. 计算中需要考虑的其他参数;
5. 短路电流计算的实例。

该标准的实施可以有效地保证电力系统的安全运行,减少短路事故的发生,提高电力系统的可靠性和稳定性。
