Influences of distributed control system transformation on the economic operation of supercritical unit

Abstract

Abstract:

Abstract:In order to improve the operation safety and economy of unit, a distributed control system (DCS) optimal transformation of supercritical unit boiler of a certain power plant is conducted. Through comparing and analyzing the one year operation data and the test data of preboiler coal quality, fly ash and slag before and after the DCS transformation, and analyzing the influences of changing main operation parameters on coal consumption of power unit using heat deviation analysis, this paper comprehensively evaluated the influences of boiler DCS transformation on the economic operation of unit under different preboiler coal quality conditions and operation loads. And it provided an economic and feasible method to evaluating the quantitative influences of DSC transformation on the economic operation of unit.
