Regarding to the low success of the stand-alone system when the sulphuric acid waste heat power generator is not connected to the electric grid,the existing problems of the power control system have been analyzed.The improvement strategies have been proposed and good results are obtained. A set of automatic and stand-alone power control equipment for the sulphuric acid waste heat power generation system has been developed.The power control equipment improves the capability for automatic malfunction identification,enhances the safety and reliability of the plant operation; reduces operation cost,and brings profit and benefit to the society and economy.
