Digital Control for Three Phase Servo Stabilizer

This paper proposes the design and implementation of Digital Control For Three Phase Servo Stabilizer servo controlled voltage stabilizer in an industrial project. Since the voltage fluctuation comes in the power system, there are many problems developed in the line voltage like distortion, fluctuation, heating, noising, accuracy, power rating, voltage range (230+5%) and power capacity less than 600 VA. To remove these problems, we use voltage stabilizer before the equipment for protection. Mainly two types of stabilizers are present in the market world, one is automatic/line voltage stabilizer and other is (analog and digital) servo voltage controlled stabilizer/regulator. The proposed architecture consists of centralized control unit and distributed control unit. Centralized control communicates with distributed control via I2C communication. In case of failure of centralized control distributed control work. As a result when voltage is low or high servo motor adjust the wiper and gives constant voltage at the output to the set point provided.
