Study on Boiler Automation using PLC and SCADA

Various controlling mechanism are used to control the boiler system so that it works properly. In order to automate a power plant and minimize human intervention, there is a need to develop a Boiler Automation system. Safety and efficiency are always given a prime importance by the boiler manufacturers and steam users. Over the time, there has been a significant improvement in boiler performance as far as these to parameters are concern. As the technology advances, there is always a scope to perform still better on safety and efficiency. Study of wireless SCADA system, which is powerful setup for monitoring and controlling the various applications from remotely, placed, is presented. Wireless SCADA is required in those applications when wire line communication to the remote site is probability expensive or it is too time consuming to construct. The seminar discusses the concept of monitoring, recording and controlling of a small part of the boiler process. This is done by using PLC and SCADA. The PLC and SCADA are connected with a wireless medium that is the Bluetooth module. The boiler process consists of parameters such as, temperature, level, and pressure. The effect of these parameters, when they exceed their limit is shown in SCADA and its resulting control is done on the real time operation of the boiler. This is done with the help of Bluetooth module, which will be wirelessly used to connect the PLC and SCADA.
