In this paper, it will be tried to briefely talk about electronic system design. In these 20 years, electronic system such as other sciences has improved. From analog and digital circuits toward nano bio systems. It will be discussed the main methods of electronic system design not only in analog and digital systems but also about nano and bio electronics systems.

This study presents an analysis of voltage stability of the electrical power system with the integration of renewable energy and the improvement of the conventional analysis using the artificial neural network (ANN), which is mainly focused on the effect of distributed generator-solar (DG-Solar) towards the electric power system. Real power and reactive power margins of both voltage stability are expressed as VSM (P) and VSM (Q), respectively. They are obtained from the actual power-voltage (PV) and reactive-power (QV) curve, which is created for each series by a series of load flows by incrementing P and Q load. Then, the system will integrate with 5MW, 50MW and 100MW of DG-Solar to compare the electric power system before and after the integration. The results are observed and compared for both situations. After that, an analysis improvement is made by using ANN-based model to predict the values of VSM (P) and VSM (Q) without having to perform PV QV Curve and calculate VSM (P) and VSM (Q). IEEE 30-bus was chosen as the electrical power system. The load flow analysis and ANN-based model are simulated and developed by using MATLAB software.

Railways are one of the most commonly used modes of transport by a wide range of the population. Safety is an important factor in any transport system. Regular changes are being made to ensure safe and efficient travel of passengers. Yet, there are more problems need to be considered because of the high usage of railways. Fire accidents in rails are one of the major problems which threaten passenger's safety. To address these issues we propose a system in which the rail compartments are coupled electromagnetically whereas in the existing system the rail compartments are coupled mechanically. The foremost thing aim of the proposed system is to save the people life and the public assets. In this system, if a fire is sensed in a compartment, it will be isolated from other compartments by de-energizing the electromagnets in the coupling to prevent the spreading of fire. Then the location of the affected compartment is sent to the nearby railway station for rescue work. This system also aids in some emergency cases. Whenever a train is stopped in need of some external help, the location of the train is sent to the nearby railway station to address the emergency within seconds.

Inclusion of Distributed Generation in the power system facilitates many features like voltage profile correction, improvement of power factor, network reliability, loadability enhancement that improve the performance of the system. Vast increase in the energy requirements to cope up with emerging trends in the community, all types of loads like residential, commercial, Industrial etc demands network up gradation. The urgency of network restructuring may be differed by an appropriate deployment of Distributed Generation in the system. Whereas, it is found that improper allocation of DGs may also degrade the system performance due to increased power losses, declined voltage profile etc. Thus, now a day’s network operators are paying wide attention towards appropriate DG allocation. This paper introduces a Modified Transmission Parameters Method considering the loss minimization as a constraint, for Siting and Sizing the Distributed Generator (DG) for installation in Distribution System based on Two Port Transmission Equations. It demonstrates an implication of Distributed Generator in power system to attain the enhanced system loadability. It also analyses the number of buses swept up from the competition of being an optimal location for DG allocation. Thus, it can be said that the proposed method facilitates enhanced ability of the system to sustain load expansion without network upgrades along with evaluation reduced candidate locations for DG installation called as ‘Inapt Locations’.
