Some main points about the development of a practical system of tidal analysis and prediction are given in detail in this paper,including the main design of the system,automatical tide selection and optimization,the theory of analysis and predication,detailed design of the system,the tools of system development,and special features of the system.

With method of numerical aerodynamic shape optimization of CFD, we try to add aspirated hole as a design variable to automatic optimization of turbomachinery blade, hope to develop ability of blade and explore a effective method to improve flow, with which we can design higher performance turbomachine.

The article introduces a kind of decomposition-coordinate distributed optimal power flow algorithm which based on region division and auxiliary problem principle (APP).

Security Region Based Optimal Power Flow of Power Systems;

It brings the conventional optimal power flow algorithm a great deal of difficulty and challenge.

This paper reviews fundamental content of Demand-Side Management and primary theory of Optimal Power Flow of electric power system first,based on which a DSMmodel of OPF is brought out considering Interuptable-Load Management.

Analysis and research of OPF calculation;

One of the main motives of electric utilities is to find out the scheme with minimum generation cost by means of OPF.

Based on the theoretical analysis and the practical procedure of the Optimal Power Flow, this paper presents the practical strategy of OPF.
