Remote substation monitoring and control

Automation of power distribution system has increasingly been adopted by power utilities
worldwide in recent years. As part of its efforts to provide a more reliable supply to the customer and to
enhance operational efficiency here we have developed substation automation. The automation of the
entire power system can be achieved by a proper monitoring and control. Monitoring refers to
monitoring of voltage in the feeders, transformer or P.Ts found in a substation whereas control refer to
actions such as feeder reconfiguration, fault dripping and other relay control actions.
This project presents the approach adopted in implementing the Substation automation system
and the benefits accrued through incorporating system. Electric power substation is an important part of
electric power system in delivery of electricity to consumers. The project hardware contains three
modules they are a remote voltage monitoring system, remote relay control and power system transient
analyzer. The voltage monitoring is used to remotely display the bus bar voltage. This module can also
be used for display of current and temperature of transformers by the addition of suitable transducer.
The remote relay control is used to remotely control 8 relays using RF waves. The range of these
systems depends on the number of power amplifiers used and the power supplied to the transmitters.
This module can be used for relay control in locations where human presence is not possible.
The transients occurring in power system can be observed in matlab using a C.T, this is
demonstrated in the third module
