Application of Variable Frequency Speed-governing System for Condensate Pump and condensate booster with DCS
Abstract:This paper introduces a project for No.1 unit with variable frequency governing system for condensate pump control. the system has gain electricity factory condensate pump variable frequency control with DCS. Improve controlling character of deaerator level and condenser level control. We put forward the control strategy for interlock protection between two Condensate Pumps and other questions. and solve many problem after finish the project. save energy and gain effect as expect.
Key words:condensatepump condensate booster,variable frequency speed governing DCS
