摘要
有色冶炼厂的余热发电以余热发电机组为核心,利用余热锅炉排出的高温蒸汽,驱动汽轮发电机组,将发出的电直接并入厂内电网,实现资源的二次利用,产生直接经济效益。余热发电厂其保护配置和整定计算是否合理,关系到设备自身的安全稳定运行和全厂的安全稳定生产。本文以有色冶炼厂的余热发电站为例说明余热发电站的继电保护计算。
With the waste heat power generator set at the core, non-ferrous refineries use the high-temperature steam discharged from the waste heat boiler to drive the turbine generator set for power generation. The generated electricity is directly transmitted to the power grid in the refinery, achieving the reuse of resources and producing direct economic benefits. Correct protective replay configuration and setting calculation are vital to the safe and stable operation of the equipment as well as the whole refinery. This paper takes the waste heat power plant of non-ferrous refineries as an example to illustrate the protective relay calculation of waste heat power plants.
