NOUFERROUS METALLURGICAL EQUIPMENT

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.
