摘　　要：根据采样值(SV)报文特点,对智能变电站保护装置采样异常情况下保护功能闭锁和开放的处理方法进行了研究。通过对比分析得出最优方案,并提出一种用于sV异常返回时保护功能开放延时的计算方法。对SV异常的各种告警方案进行了分析,提出一种基于统计方法的告警方案;对SV检修不一致的处理方法进行了探讨,并给出了相应的处理方案。现场运行经验表明,上述方案具有较高的可靠性和适用性。According to the characteristics of sampling value （SV） message, the processing method of protection functions is studied in smart substation protection devices which are blocked or opened in the case of SV exception. The optimal scheme is obtained through comparison ＆ analysis, and a calculation formula for the open delay of protection functions after SV exception return is proposed. A variety of alarm schemes for SV exception are studied, a new method based on statistical principle is proposed. The processing method of inconsistent maintenance of SV message is discussed, and the targeted solutions are given. The operation on site shows that these schemes have high reliability and applicability.
