Abstract
In order to study the feasibility of frequency conversion of electric feedwater pump in nuclear power plant, and to provide reference for the improvement of electric feedwater pump in nuclear power plant and new nuclear power plant, this paper discusses the technical and economic aspects, and analyzes the feasibility of frequency conversion transformation of electric feed pump in nuclear power plant. The results show that there is no technical difficulty for the electric feedwater pump of nuclear power plant from the technical point of view, and the economic analysis shows that it will take about 4 years to recover the cost for the frequency conversion of the electric feedwater pump of nuclear power plant. Therefore, the frequent participation in the peak load of the power grid units can be considered for transformation, For the nuclear power units that serve as the base load of the power grid, the cost can be recovered in about 6 years by eliminating the loss of capacity, and they can be retrofitted according to the needs of the plants themselves.
