Implementation of Variable Frequency Drives (VFD) on Boiler Feed Water Pumps for Drum Level Control

Project Report from the year 2015 in the subject Engineering - Power Engineering, , language: English, abstract: The project was to convert the control of three boiler feed water pumps to Variable Voltage Variable Frequency (VVVF) drives having a capacity of 750 m3/H @ 220 Kg/Cm2 pressure and power rating of 6200 KW each. The main focus of this report is the design and development of the protection system, sequence of operation, bypass system, speed control system, drum level control and graphic interface. It also includes PID controller tuning for VVVF drive smooth control.
