摘要/Abstract

摘要：

随着机组容量的加大，重要保护系统的单信号的存在影响了系统的可靠性。依据DL/T 5428—2009《火力发电厂热工保护系统设计规定》和DL/T 1083—2008《火力发电厂分

散控制系统技术条件》的要求，针对华电潍坊发电有限公司锅炉炉膛安全保护系统为通道信号，且无单信号故障报警功能的现状，对重要保护信号进行了功能完善。完善后的重要

保护系统信号确保了系统的安全可靠运行。

Abstract:

Along with the increase of unit capacity, the single signal of some important protection systems influences on the reliability of the system.

According to the requirements of the file DL/T 5428—2009‘Technical Code for Design of I&C Protection System in Fossil Fuel Power Plant’, and the file DL/T

1083—2008‘Specification of Distributed Control System for Fossil Fuel Power Plant’, aiming at the current situation of the FSSS protection system of

Huadian Weifang Power Generation Company Limited, in which some signals are singlechannel signals and there is not the alarm function for single signal

failure, the functions of important protection signals were improved. The improved important protection system signals ensure safe and stable operation of the system.

Key words: single channel, important protection signal, FSSS (furnace safeguard supervisory system) hardware protection system, function improvement
