Energy Monitoring System USING PLC & SCADAS

Abstract

-Power management has been one of the most talked about topics in the past decade or so because of the decrease in the energy reserves. Power shutdown is a major problem now-a-days and it occurs because a lot of power is wasted in industries. My project, ENERGY MONITORING SYSTEM deals with this problem in a simple and effective way by auditing the energy usage in industries. It checks power shut downs by knowing the large amount of energy wasted in industries. I perform all this in an automated process. In ENERGY MONITORING SYSTEM, Energy Meters, PLC’s and PC’s are used for performing its operations. Multiple energy meters with a single PLC which in turn connects with a PC. VB - serial communication is used to facilitate the communication between the PLC and PC. Several PLC's in a network can also be used. The network is obviously connected using RS-485 cables, which provide universality. But PC's are only compatible with RS-232. Hence we connect a converter (that converts RS-485 to Ethernet) between the network of PLC's and the PC. SCADA- Supervisory Control and Data Acquisition of industrial processes used for serial communication to facilitate communication between the programmable logical controllers and computer.
