im a college students...
i have been assign to design and build a micro-controller based Automatic Main Failure and Transfer Switch system (A.M.F.A.T.S.).
The problem is im not quite good in programming a system. if there an expert... please help me as soon as possible, ok?
The AMF Control Panel is a specially designed panel for standby generators. It consists of a state of the art microcontroller based AMF controller for monitoring, indicating and controlling the Mains and Generator for AMF operation.
The AMF Control Panel can be operated in following modes:
• AUTO
In this mode the AMF controller takes command of the total system operation.
Sequence of operation:
i.] At power ON, if Mains is healthy the Mains contactor is turned ON and load gets power from Mains.
ii]. If Mains is unhealthy, the controller starts the generator and transfers the load on the generator.
iii.] If the Mains recovers, the controller switches the load back onto Mains and shuts down the generator after cooling time.
iv.] In case there is a fault in the generator while running, the AMF controller takes action by indicating necessary alarms and/or tripping the generator depending on the fault.
• MANUAL
In this mode the starting / stopping of the generator and load ON/OFF can be done manually from the AMF controller. In this mode if any fault occurs in the generator while running the AMF controller takes necessary action by indicating alarms and/or tripping the generator.
• TEST
This mode is used to check the health of the generator. In TEST mode the generator is started and kept ON for a fixed duration. During this period the AMF controller checks for any faults in the generator. If any fault is sensed the controller displays the same. If the generator is found healthy GENSET OK is indicated on the display.
• BYPASS
In BYPASS mode the AMF controller acts just as an indicating instrument. The system is operated from the external switches provided on the Control Panel. No action is taken by the AMF controller in case of faults in this mode.
• HOLD
INDICATIONS ON LCD DISPLAY
The LCD display of AMF Controller indicates following parameters in scrolling mode:
i.) Phase Voltage
ii.) Phase Current
iii) Frequency
iv) Power Factor
v.) KVA
vi.) KW
