Overcurrent relay is an important relay used to protect transmission and distribution feeders, transformer, bus coupler etc. It can be used as main or backup protection relays. The modeling of overcurrent relay and other protection relays is important in the research on the effects of network parameters and configurations on the operation of these relays. This research deal with modeling and simulation...
This paper presents an implementation to enhance the protection scheme of smart distribution grid. In order to improve the existing protection scheme used in Malaysia that is "Current Differential Protection", to a new level of protection that used the idea of combining the "Current Differential Protection" and "Fast Current Protection". This project was developed to...
Micro-grid system is an integrated energy system asit consists of distributed energy resources (DERs) and multipleelectrical loads operating in parallel or islanded grid. Theprimary objective of this project is to examine whether Microgridimplementation can reduce the cost of energy. It can bedetermined through the modelling bus bar system; 5-Bus TestSystem and 26-Bus Test System. This application...
This project present analysis and implementation of cross blocking feature as the solution for overcoming the mal-operation of the transformer differential relay in sympathetic inrush phenomena. The sympathetic inrush phenomena will occur to the transformers that connected in parallel. The inrush current will flow to the transformer that is already energized when energizing the second transformer...
In modern industrialized society, an Economic Dispatch (ED) of power generating units has always been occupied an important position in the electric power industry. This paper presents a Hopfield Neural Network (HNN) computation method to solve ED problem in power systems. HNN computation is expected to be reliable since HNN is essential for its progress. The objective of this paper is to describe...
