The restoration process of the bulk-power transmission system following a partial or a total blackout, has two main issues during a restoration, these are voltage control and frequency control. Special attention is therefore given to the behavior of network parameters, control equipments as they affect the voltage and frequency regulation during the restoration process. During restoration due to wide fluctuations in the frequency and voltage it becomes very difficult to maintain the integrity in the system. Inability to control the frequency may lead to unsuccessful restoration. Repeated collapse of the system Islands due to tripping of generators due to either over frequency or under frequency causes delay in getting normalcy. This paper considers aspects of computer application in restoration and Islanding in the context of Maharashtra State power system. During conditions of blackout, the process of Islanding can satisfy the power requirements for a particular area, thus assisting the grid operator as well as helping in reducing the time required for the complex restoration processes. The main obstacle in the process of restoration or Islanding is the number of switchgears located at various locations with different configurations. © 2008 Elsevier Ltd. All rights reserved.

A different approach in system restoration with special consideration of Islanding schemes

The brain continuously receives the visual information or the information corresponding to some stimulus and elaborates and perceives this information. It uses electrical signals to process this information and then analyze it. The encoding of this complex information into simple electrical signal is done by the fundamental building block in the brain, called neuron. This paper deals with the effect of bidirectional communication with the neuron in the brain that is supplying the signals coming from the neurons externally and artificially to the brain and producing the same effect as that of the original signal. The paper also describes the hypothesis being investigated using data from an epileptic patient. The idea stated in the paper can help in developing an implantable neural system that can co- exist and bidirectionally communicate with the living brain tissue and thus substitute for the lost cognitive function due to damage and / or disease. © 2006 IEEE.

This paper highlights the Simulation of Multiple-Infeed Converter (MIC) System with the help of "Matlab / Simulink"As AC/DC systems become further integrated as multiple in feed converter (MIC) system can be expected to become more common. In this a) different categories of MIC systems are defined , b) the impact of AC system strength & c) Dynamic interaction between HVDC system connected to AC Buses in close proximity and performance of such systems are highlighted. Simulation results with the help of "Matlab/ Simulink" are presented which provides some insight into dynamic behaviour of 1 category of such systems.

The availability of electrical energy ensures development and progress while its non-availability means stagnation or 'back tracking'. The condition of 'No Power' [1] is the costliest state and leads to social, economical and production loss. Power system blackout means inconvenience and hardship to society. Uninterrupted power supply is essential for the national productivity and social structure and hence system must be made flawless at any cost. Reliable and disturbance free electric power supply is recognized as a key to 'Societal progress throughout the world'. Grid failure occurs due to continued overstressing, low frequency operation, increased load demand, peaking characteristics of the demand, ineffective load control, reduced level of security due to opening of interstate lines and violation of grid discipline. After occurrence of severe system disturbances, the system may split into parts, which may or may not survive depending on the load generation balance. The part system containing the generation sources and certain loads, which are planned to be separated from the main grid during system disturbance at, preconceived points either through under frequency and / or directional power relays are called 'Islands'[2]. During restoration due to wide fluctuations in the frequency it becomes very difficult to maintain the load-generation balance. Inability to control the frequency may lead to unsuccessful restoration. Repeated collapse of the system island due to tripping of generators either due to over frequency or under frequency causes delay in getting normalcy. In this situation the computer-computer links between the State Load Despatch Centre (SLDC) and Area Load Despatch Centre (ALDC) play a key role [3]. The priority during the restoration period such as railway traction, essential consumers such as water supply scheme, hospitals etc and lastly to the civil societies should be given. It is also necessary to have provision of disturbance recorder and event logger at power generation stations and various interconnected substations. These and other major aspects are considered in proposing the islanding scheme of the Pune city. Copyright © 2006 The Berkeley Electronic Press. All rights reserved.

This paper highlights the case studies of steel plant and Municipal Corporation taking into consideration the power quality improvements. The main reason we are interested in Power Quality is economic value. The increasing application of electronic equipment and Distributed Generation has heightened the interest in Power Quality in recent years and this has been accompanied by special development of special terminology to describe the phenomena. Meeting customer's expectations and maintaining customer confidence are the strong motivators behind maintaining the Power Quality. Distributed Generation has started gaining importance in our country and can become the answer for increasing the power failure. Power failure leads power interruption leading to insecure and unreliable Power System.

Improving power quality by distributed generation

A Novel Centroid Based Pulse Width Modulation (PWM)[1] switching strategy is proposed for full bridge inverter application. The objective of new switching strategy is to minimize both the THD and lower order harmonics. The proposed approach provides better performance in terms of improved THD and lower order harmonics when compared to other conventional PWM techniques. The Centroid Based technique (CBT) described here in is to give a high quality inverter output waveform without leading to significant switching losses. In the proposed centroid based switching strategy, the width of each switching pulse is proportional to the corresponding area of the sampled reference waveform while the position of each pulse in the time domain is aligned with the centroid of the corresponding area of the sampled reference waveform.
