In this paper we discuss about the power quality analysis for matrix converter. The proposed system consists of a Shunt Active Filter which improves the power quality by eliminating the Total Harmonics Distortion. Normally the Matrix Converter itself injects significant harmonics to the existing system. In proposed system the approach will completely remove the Total Harmonics Distortion & reduce the effect, which increase the Power Quality. The methodology has been tested and verified using the Mat lab/ Simulink. © Research India Publications.

In recent years renewable sources such as solar, wave and wind are used for the generation of electricity. Wind is one of the major renewable sources. The amount of energy from a Wind Energy Conversion System (WECS) depends not only on the wind at the site, but also on the control strategy used for the WECS. In assistance to get the appropriate wind energy from the conversion system, wind turbine generator will be run in variable speed mode. The variable speed capability is achieved through the use of an advanced power electronic converter. Fixed speed wind turbines and induction generators are often used in wind farms. But the limitations of such generators are low efficiency and poor power quality which necessitates the variable speed wind turbine generators such as Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous Generator (PMSG). A high-performance configuration can be obtained by using a PMSG and a converter in combination AC-DC-AC connect between stator & rotor points for providing the required variable speed operation. © 2014 Institute of Advanced Engineering and Science.

The research and design of embedded pulse monitoring instrument overcome the shortcoming of traditional pulse diagnosis system. The instrument has simple structure stable and reliable operation, high accuracy, low power consumption, good portability full featured function, and extensive application occasion. The real time monitoring system for cardiac patient physical state is based on wireless transceiver module technology. It can be taken by patient and keep the patient moment intact because it is miniature and portable .The system can monitor and record the physical states and moment parameters real time, and the provide auxiliary means for the correct diagnosis of doctor. With intelligent transceiver module, the sign of acute disease for patient can be found early, and then the patient can be helpe in time, the sudden death of patient can be avoid. The wireless transceiver module technology can be suite for short distance communication, and the transmission distance is limit only about 10 meters, and then it can be suitable for in-patient monitoring. © 2005 - 2014 JATIT & LLS.
