| Hydropower plant hydraulic transient is a delicate procedure, which contains complex relation between water, machine and electricity. It has a lot to the optimization of the inlet power generating system and the safely running of the hydropower plant. So, the researcher of hydraulic transient is very necessary in the Hydropower plant. On the study of the former researchers, several critical problems are studied. The main aspects as follows:1. Recall on the development of hydraulic transient, describe its research achievement and development prospect. Follow that, the main research aspect and its aim are presented.2. Mathematic model is founded, on the premise that is taking all energy lose, friction changing and all boundary limits into consideration. Computing chart and program is also given.3. 3-demension special curve is draw, in which the method of interpenetrating is used. This has the several features, such as easy to read, convenient to program, high credibility, visualization of the result. In all it is fit to the numerical simulation and analysis of water plant hydraulic transient.4. Derive the formulation of the scroll case and draft tube, which makes it easy to compute.5. According to the founded mathematic model, numerical simulation and analysis of hydropower transient of hydraulic plant software, which basedon Windows is developed in MATLAB. This can carry out every simulation about the hydroelectric generator unit's running status.The simulation is given on the real application of Zi Ping-pu project. Also handbook about how to use the software is given. 6. Give the overview of the whole paper, point out the weakness and defects of the paper. |
