Simulation Studies of an Integrated Overcurrent Relay Protection Scheme for Distribution Systems

This paper presents an integrated protection technique for power distribution systems. A novel integrated protection scheme based on overcurrent protection technique for distribution system is described, in which a specially designed protection relay is installed at each substation of a network and responsible for the protection of every line sections connected to the substation busbar The conventional directional overcurrent and the new adaptive accelerated protection algorithms with multiple settings are implemented into the relay to cover all the protected line sections. The paper includes studies of a typical multi section distribution network to demonstrate the principle of the scheme. Studies show that the new scheme not only offer the new protection features for individual power line section, but also provide the characteristics of integrated protection.

Design Integrated Distillation Columns for Binary Systems

The purpose of this study is to contribute methodologically, through a systematic study of the application of different optimization techniques to design integrated distillation columns in binary, for it established one optimization technique, deterministic, was optimized distillation column at steady state. For this part was used tabu search to solve the type binary problem. For each choice of the search whole continuous variables were optimized with the deterministic method for process design perturbation is applied to the molar fraction of the feed. It develops and implements the mathematical algorithm solving the problem, then validation of the methodology proposed dynamic simulation of the system is compared with and without control, with both traditional and integrated approaches.

Design of Virtual Simulation Experiment System based on VB and VRML

This paper introduces the design and Realization of NC simulation teaching system based on VB and VRML technology. The paper realize functions using the new Parallel development platform launched by Graphics Company for VRML environment （Cortona SDK）, and uses the object oriented programming method based on ActiveX technology in the technical system. Practice has proved that the system has good stability and strong simulation function.

Three-Dimensional Visual Analysis for Construction Layout of Reservoir Project

It is difficult to analyze the inter-relationship for the construction layout of a reservoir project scientifically and intuitively.According to the characteristics of broad field and huge information,the modeling methods of digital terrain and solid model as well as the techniques of texture mapping and scene navigation are adopted.The simulation system is developed by C program language,which includes the functions of the interactive navigation of 3D scene,the visual inquiry of project digital model information,the storage and management of project information.A certain reservoir is taken as a case.The 3D visual analysis for the construction layout and engineering information are obtained.The proposed system is of great advantages in dealing with large amount of information and the method provides a theoretical basis and technical support for the construction layout of a reservoir project.

Research and Simulation on the Small-scale Streaming Data Transmission Communication System based on ARM and FPGA

In this paper, we conduct theoretical research on small-scale streaming data transmission communication system based on ARM and FPGA. Compared with network layer IP multicast, it does not need to change the underlying structure of the network with the realization. Aa are day by day mature as a result of the embedded technical high speed development and the GPRS technology with use the embedded system essence small, special-purpose strong, the system simplification and the GPRS network cover characteristics and so on whole world. Under this basis, this paper proposes the new ARM and FPGA based small-scale streaming data transmission communication system. The implementation of the system proves its effectiveness.
