Automation Based Energy Management System in Industry Using PLC AND SCADA

Electronics and Electrical Engineering

Power is inevitable part in all industries. Power is generated in power plants, and transmitted through large distances to the loads which may be a small scale industry or a large scale industry or even a household. The power generated in power plants should be managed in order to facilitate the smooth operation of the system. The basic idea behind any power management system is to manage various loads. These loads are models for different areas of the city. If the load in any area increases then there is every chance that the power station may trip. Hence to avoid this from happening we have proposed a hardware based circuit. When any one load increases then one of the loads that are connected out of many is disconnected. The priority of disconnecting is variable and can be changed from time to time. The current requirement of different load is different as the time varies. Hence according to that changing priority we assign different priority to different load. When the current in any one load increases then the total load on the generation process increases. The excess load may cause the power plant to trip. The cost involved for restarting a power plant is much more. So when the load increases it is advisable to disconnect any one of the loads that are connected. This process is implemented in an automatic way in power management project.
