Smart grid revolutionizes the current electric power infrastructure by integrating with communication and information technologies. With wireless sensor network, smart grid enables both utilities and customers to transfer, monitor, predict, and manage energy usage effectively and costly. However, the increased application of wireless sensor network also introduces new security challenges, especially related to privacy, connectivity, and security management, causing unpredicted expenditure and disaster to both utilities and consumers. In order to build a reliable wireless sensor network for smart grid, an application review and taxonomy of relevant cyber security and privacy issues is presented in this paper. A unified framework for identification of applications and challenge issues of wireless sensor network in smart grid is developed.

Abstract

This project is developed for speed monitoring and control of induction motor through Internet. It consists of a microcontroller unit. The embedded controller is the CPU that decides the operation of the unit. The embedded controller used here is PIC16F73 microcontroller. Since the controller has the inbuilt peripherals it is called as embedded controller. An opto coupler with IR transducer is connected with the induction motor to sense the speed of the motor. According to the speed of the motor, the sensor sends signal to the microcontroller. The microcontroller sends corresponding signal to the PC through serial port. The software in the PC is developed for receiving the data and displaying the speed. The user can view the speed and also control the speed of the motor in online manner. When the user presses the specific button in the PC, the software sends corresponding signal through the Internet. The microcontroller receives the signal through USART and controls the operation of the motor. The microcontroller program is written in assembly language and the Design and port programs are written in ASP.Net.
