ALERATING SYSTEM DESIGN USING PIC16F877A FOR POWER DISTRIBUTION SYSTEM

Abstract

In the last few years we have witnessed a strong interest in the protection of Critical Infrastructures such as power distribution networks, power plants, refineries, water distribution, transportation systems, hospitals and telecommunication networks. This paper presents a full design of alerting system using PIC16F877A microcontroller for power distribution network. The proposed system is used to monitor the loads distribution of electrical cables, and works fast and easy to control the cables of distribution and measuring the loads and send warnings to the concerned authorities in case of fault. The alerting system aims to follow up the power meters of the electric company and make sure that all the cables running under allowed load without any defect (overload). The alerting system uses computers in monitoring and sending alerts in emergency situations from a safe place and away from the measuring devices (in the control room of the company). Computers are connected to the control unit via telephone network, where the computer provided with monitoring, warning and communication program and send the warning voice messages; meanwhile the control unit is responsible for receiving data from the measuring devices and then sends this data continuously to the computer and the computer will store the data. This alerting system is applied as real time application to Gaza Electricity Distribution Company and works well and shows good result.
