Auto Power Supply Control From Four different Sources
Project Area of Specialization Artificial IntelligenceProject SummaryThe main objective of this project is to provide uninterrupted power supply to a load, by selecting the supply from any source out of 4 such as mains, generator, and inverter and solar automatically in the absence of any of the source. The demand for electricity is increasing every day and frequent power cuts is causing many problems in various areas like industries, hospitals and houses. An alternative arrangement for power source is a must. In this project uses four switches to demonstrate the respective failure of that power supply. When any of the switches is pressed it shows the absence of that particular source, switches are connected to microcontroller as input signals. A microcontroller of 8051family is used. The output of microcontroller is given to the relay driver IC, which switches appropriate relay to maintain uninterrupted supply to the load. The output shall be observed using a lamp drawing power supply from mains initially. On failure of the mains supply(which is actuated by pressing the appropriate switch) the load gets supply from the next available source, say an inverter. If the inverter also fails it switches over to the next available source and so on. The current status, as to which source supplies the load is also displayed on an LCD. As it is not feasible to provide all 4 different sources of supply, one source with alternate switches are provided to get the same function. The project can be further enhanced by using other sources like wind power also and then taking into consideration for using the best possible power whose tariff remains lowest at that moment.
Project ObjectivesThe main objective behind our project is to over come the problem of load shedding and circuit breakdown in our local region where long lasting and continius systems are still a theory, this project will be positively cost effecting. Installing such systems In our local region shall bring awareness among the people who are yet to be awared.
Project Implementation MethodThere are several steps implement to complete the project in which the first and the most necessary step is to design an accurate and perfect circuit to control and switching four different devices. The auto power supply control system is very convenient system for that consumers who want to attains uninterruptible power supply from different sources such as solar, main, generator and inverter.
Benefits of the ProjectThe system is highly efficient in remote areas.
Businesses relating to data information or software base operations has a highly need for such a project.
To stop the a major cause of illegal acts in business environment
Money saving/ data saving
Moving on from “Effort Reducing” to “Effortless”
Technical Details of Final DeliverableThis auto power supply control system works on the principle of auto function for switch over the load to other available source without wasting any time or switch off the load. Here for the demonstration purposes we have used the selection keys for switch off any source of supply. In this system, the microcontroller which is very essential component of this system always, keep sensing the whole available sources. When any source is switched off through the selection keys then the microcontroller shifted the load to the other supply source by giving the signal to the relay driver IC then the relay driver IC switched on the appropriate load relay. The whole function is done by the microcontroller is micro seconds and this shifted time can be changed during the programming of microcontroller. Here 4 load relays are used which are connected in parallel with load and 4 sources of supplies are also connected in parallel with these load relays. These load relays consist of normally open and close contacts and are operated through the relay driver IC. We have checked this system by connecting the lamp at output side as a load when any interruption is take place during the shifted time then the lamp is blinking but here there is no any blinking take place during the shifted time means there is no any interruption in supplying the power at output side.
