The Controller Area Network (CAN) is a serial, asynchronous, multi-master communication protocol for connecting electronic control modules in automotive and industrial applications. CAN was designed for automotive applications needing high levels of data integrity and data rates of up to 1 Mbit/s. In this project Controller Area Network protocol is implemented using on chip Motorola Scalable Controller Area Network (MSCAN) of MC9S12DP256B 16-bit Microcontroller. The application we have taken up is “Monitoring of Temperature using LM35 based on Controller Area Network architecture” .The system is constituted of two CAN nodes, each CAN node is formed by a transceiver MC33388 and 16-bit microcontroller MC9S12DP256B. The first stage consist of the conventional sensor of temperature (LM35) that converts the room temperature into voltage signal, and then this signal is conditioned and then the signal is transmitted to the input of the A/D converter of the microcontroller. The A/D converted data is transmitted to the CAN node 2 using the CAN architecture. At node 2 the received temperature readings are displayed using an alphanumeric LCD display of size 16X2. Node 2 consists of a keypad through which user can enter the maximum operating temperature of the device. According to the maximum temperature value entered the node 2 can take decisions and controls temperature source which is at node1 by sending control signals via the CAN network as per the user requirements. In this thesis we have concerned with design techniques for implementation of CAN nodes for data monitoring and taking appropriate decision based on data in the control system. Implementation of CAN for temperature monitoring and controlling the device is successful and the same idea can be applicable to monitor tire pressure monitoring system, Adaptive Cruise control, power window and Engine management systems in Automotive. This leads to decentralization of control system in vehicles. This can be extended to industrial control applications.

Antennas have a big role in wireless communication system. Wireless Communication system requires compact, multi band antennas that can dynamically change some of its fundamental parameters such as frequency band, and gain. The novelty of the proposed work lies in using one conducting strips that support operation at different frequencies. Therefore the main motto is to obtain triple band of frequency to improve the frequency congestion in wireless communication system. Triple band Rectangular slotted Monopole antenna with parasitic line is designed by inserting a single strip on antenna because of this the antenna gives enhanced bandwidth with increased gain at all triple band frequencies, which attains a bandwidth of 8.75% for │S11│ ≤10dB return loss, 12.69% for │S11│ ≤10dB return loss and 5.06% for │S11│ ≤10dB return loss at centre frequencies of 2.4GHz, 5.2GHz and 8.1GHz respectively. The work carried here is applicable for ISM band (which is kept reserved for industrial, scientific and medical application), S-band, C-band and X-band at frequencies 2.4GHz, 5.2GHz and 8.1GHz respectively. These three frequencies are also well suitable for wireless communication.

The size of individual wind power plant is continuously increasing, while sites with good wind conditions often are located far from electrical loads. This often results in wind power plants connecting to weak transmission grids.Among the technical challenges, the voltage stability is identified as most critical to the stable operation of wind power plant within weak grid. If the wind power plant itself cannot provide sufficiently fast and extensive compensation, the typical solution for the voltage stability problem is to install dynamic reactive power compensation with fast voltage control capability, such as Synchronous Condenser. In analysing the electrical networks power flow solution is very essential. There are numerous power flow models for transmission as well as distribution systems. It is also evident from the literatures that several new models exclusively for distribution networks are being developed. This research work carried out on a dummy power system network having wind power plant and Power System Stabilizer (PSS). A MATLAB SIMULINK model for the same system has been developed to analyse that in case of three phase fault the coordination between wind farm and PSS could improve the transient stability of the power system.
