In this paper, the communication between Over-Current Relay agents is realized using DNP(Distributed Network Protocol), which is the standard communication protocol of distribution automation system in KEPKO. The key words in OCR agent communication are defined and represented by use of DNP application function code. And the DNP index for OCR agent is defined. The proposed communication scheme is tested by use of Communication Test Harness, a test tool for DNP protocol to show its soundness.

This paper suggests an optimal parameter setting method by use of parametric protectability index, as the objective function. In this paper, a gradient based optimization method is used under the assumption that the initial values of a parameter is in a convex set including the optimal value, which is verified by a plenty of simulation studies. The proposed method is applied to a sample distribution network to shows its effectiveness.

The video game industry is obsessed by the perception of "Next Generation Game". Appearance of the next generation game console has required the video game industry to renovate new technologies for their entire production. This tendency increases a huge mount of production cost. Game companies have to hire more designers to create a solid concept, artists to generate more detailed content, and programmers to optimize for more complex hardware. All those high cost efforts provide great locking games, but the potential of next generation game consoles does not end there. They also bring possibilities of the new types of gameplay. Next generation game contains a much larger pool of memories for every video game elements. The entire video game used to use roughly 800 animation files, but next generation game is pushing scripted event well over 4000 animation flies. That allows a lot of very unique custom animation for pretty much every action in the game. It gives game players much more vivid and realistic appreciation of the virtual world. Players are not being able to see any recycling of the same animation over and over when they are playing next generation game. The main purpose of this thesis is that defines the concept of next generation game and analyzes new animation-pipeline to be used in the shooter games.

This paper has described in Electric Vehicle Battery Management System(EV BMS). EV BMS manages the input/output energy of the traction battery, and provides the optimum environment condition during charging/ driving through the communication with other controllers. In this paper, we introduce our BMS for Santa Fe EV. Hyundai Motor Company has been developed EV since 1990. Recently, Santa Fe EV has been demonstrating with the environmental friendly technology. Two year real road testing program with electric powered Santa Fe is being undertaken by HMC in Hawaii.

In this paper, a communication module is proposed to be applied to communication between over current relay (OCR) agents in multi agent protection system. A multi agent system can achieve a global goal beyond the ability of each individual agent by working together, in which it is the prerequisite for each agent to be able to exchange or share information or processing status with other agent. The proposed communication module is purposed to enable not only each agent to bring about its own goal, but also the whole protective system to provide much improved coordinated protection. It is applied to a self adaptive protection system for a distribution network using multi agent concept to show its effectiveness.

The digital current differential relaying scheme is widely used for primary protection of 765(kV) power transformer. The current differential relay pickup the internal fault at the threshold which is set at 30% of rating current. Margin of 30% include current transformer error 5%, relay error 5%, on load tap changer error 7% and margin factor 140% obtained from the field experience. In this paper transformer protection relay and relay setting rule of high voltage power system are discussed. And we verify the correctness of relay setting rule with current differential relay using Matlab simulation.
