This paper features on implementing the governor control automatically in steam turbines in the boilers that can be used in power plants. It mainly focuses on controlling the speed of the PA, ID, FD fans. Thus the boiler parameters in the boiler are constantly monitored and the steam is generated according to the need. The automation can be easily done using Remote Terminal Units (RTU) or PLC (SCADA). The turbine speed can be controlled and monitored. The SCADA is used to monitor the system, PLC (Programmable Logic Controller) is also used for the internal storage of instruction for the implementing function such as arithmetic, counting, timing, sequencing and logic to control through digital or analog input/output modules various types of machines processes.

The main criteria required for all the electrical and electronic device is the voltage. It plays vital role in a power quality. It is planned to provide a transformer with multiple taps and selecting the taps required for the moment will be automatically selected by the on-load changeover system which is operated by the controller. Computer acts as a controller with the aid of the C software. Voltage transducers are used to sense the voltage and ADC to convert into digital signals. These digital signals arte interfaced with computer which in turns operates the On Load Tap Changers (OLTC). Suitable taps are selected and its drive relays are operated by the computer through opto-coupler and switching transistors.Keywords
