Introduction
AMF(Automatic Mains Failure) panel and generator(Battery) packages are designed to provide emergency power during a mains supply failure.
Existing system
The AMF panel (Automatic Main Failure) Device is widely used in the industries to control and detect the main failure.
But common type of AMF panels works as a power source switcher during a power failure.
In some cases the AC power monitoring is very critical and there are conditions which demand highly precise of parameters like input frequency and voltage.
Most of the AMF panels are insufficient of detecting the changes in frequency or voltage.
If the fluctuations in the above mentioned parameters exist, it can lead to disastrous results even in the damage of costly machinery.
Most of the existing AMF panel have a low speed switching relays which may lead to fatal results in long run.
Proposed System
To get an alternative to this scenario, we here follow a new approach to design an advanced Micro controlled AMF panel.
In this approach, an efficient Micro-controller will monitor the parameters of input main power supply.
Its high speed ADC will read the parameters in real time. Also it will hold some previous reference data so that it can detect the changes in the input power parameters(Voltage fluctuations).
The device uses a high speed, high power thyristor family components that will increase the switching speed hence the performance.
Working
During operation, the control panel of the AMF monitors the mains entering the circuit.
If a mains supply fails or there is any kind of voltage fluctuation, the panel disconnect the mains from the load, apparently gets connected to the battery and its output gets is given to the load. (The load being appliances, lights, etc in use within the house at the time of mains failure).
The Battery continues to supply to the load until the mains supply returns. As soon as the mains supply returns, the battery automatically detect, disconnect and stop the battery and the mains supply gets re-connected to the load.
The AMF panel reverts to the standby mode and remains ready to respond to any another accidental mains failure.
Advantages
It has a high speed switching relays.
Load saving characteristics.
Low power system (Consumes low power).
High speed switching relays.
Introducing this to the home appliances and by the use of GSM, the house owner has the provision of sending a message back to the device if he wants to switch off the device.
