Abstract - The purpose of this project is to acquire the
remote electrical parameters like voltage, current and frequency and send these real time values over gsm network using gsm modem/phone along with temperature at power station. This project is also designed to protect the electrical circuitry by operating an spdt relay. This relay gets activated whenever the electrical parameters exceed the predefined values. The relay can be used to switch off the main electrical supply. User can send commands in the form of sms messages to read the remote electrical parameters. This system also can automatically send the real time electrical parameters periodically (based on time settings) in the form of sms. This system can be designed to send sms alerts whenever the relay trips or whenever the voltage or current exceeds the predefined limits. This project makes use of a microcontroller. The controller can efficiently communicate with the different sensors being used. The controller is provided with some internal memory to hold the code. This memory is used to dump some set of assembly instructions into the controller. And the functioning of the controller is dependent on these assembly instructions. The controller is programmed using embedded c language

1. INTRODUCTION The distance between the generators and load may be in terms of hundreds of miles hence the amount of huge power exchange over long distances has turned out as a result of the lack of quality of the electric power. During the earlier development stages the issues on quality of power were not frequently reported. Demanding the quality of power being delivered at the user side has raised the alarm due to the increase in demand of electricity in the customer side. A huge amount of power is lost during the transportation of the general power which leads to the reduction in the quality of power received at substation.

To Improve the quality of power with suffer solution it is necessary to be familiar with what sort of constraint has occurred. Additionally if there is any inadequacy in the protection, monitoring and control of a power system. The system might become unstable. Therefore it necessary a monitoring system that is able to automatically detect, monitor, and classify the existing constraints on electrical lines.[1] Today electricity still suffers from power outages and blackouts due to the lack of automated analysis and poor visibility of the utility over the grid.WSN will give the utility provide the needed view by collecting information from the different sub-systems of the grid. A sensor node will decide information or to slightly delay this notification (whether to immediately notify the sink about this information.).PB COOP operation 1) The evaluation of sense data: we define three priority levels {0, 1, and 2} 2) The selection of a communication policy: priority 0-no further action is performed, priority 2-value is sent to the sink because it is considered as urgent and a notification needs to be directly sent, priority 1-we consider that value should be reported because it may signal as fault or a problem that is less urgent than priority-2 data.[2] Development of intelligent electronic devices (IED’s) brings a leap in the development of substation. Large scale development of IED’s create huge amount of data either recorder continuously or captured when IED’s triggered by an event such as a fault or disturbance. Criteria for the new system: cost, reliability, cyber security, scalability and maintainability and minimal co-dependencies.the high voltage substation includes the primary equivalent such as C.B, transformer, protection devices and the secondary equivalent such as monitoring, control and protection devices. In addition, due to large number of wires in a highly electromagnetically “polluted” substation switchyard
