Automated control of complete equipment Francis turbine generator for hydro power plant
The stability, efficiency and cavitation corrosion of water turbine set are three main evaluation indexes. With the development of water turbine units towards the direction of large size and large capacity, its own natural frequency also decreases, and the frequency of the interference excitation force is the same order of magnitude, therefore, the stability of the operation of water turbine units becomes a more important problem. The design of turbine runner directly affects or determines the three major technical indicators, but at present, there is still a gap between China and foreign countries in the design of turbine runner. The dynamic characteristic analysis and comprehensive optimization design of turbine runner is a very meaningful and difficult research topic in turbine design. This article has carried on the beneficial research and exploration to this, the following main results: 1) from the water and the coupling effect of wheel, more systematic and comprehensive analysis of the wheel under the condition of the dynamic characteristics, including the wheel and blade are calculated respectively in the air and the natural frequency and main modes in the water, the rotating centrifugal force is calculated under the wheel structure in the running state and flow water pressure influence on the dynamic characteristics of the wheel, wheel under the operation condition are analyzed, the possibility of resonance. Through the comparison and analysis of the calculated results and the related test results, it provides the reference guidance for the design. 2) on the basis of computational fluid dynamics (CFD), developed a fluid-structure interaction (FSI), a calculation model for viscous fluid medium, using the ALE format to handle moving boundary between fluid and structure, fluid domain and solid domain respectively independent calculation, process control transfer fluid pressure and displacement and speed as the boundary conditions of the other party, solid coupling calculation. On the basis of ANSYS5.6, APDL programming language is applied to control fluid calculation and structure calculation to realize the solution of coupling system. The effectiveness of the proposed method and program is demonstrated by three examples, and the dynamic stress generated by the hydrodynamic pressure of the runner under different working conditions is calculated and analyzed. 3) the field test and calculation of a water turbine are carried out. Through comprehensive research and analysis, the causes of the turbine's violent vibration, noise and blade cracking are obtained, and the Suggestions for solving the problems are put forward. 4) on the basis of the dynamic analysis of the runner structure and combined with the hydraulic design of the runner, genetic algorithm was used for the first time in the comprehensive optimization design of the runner, and the software for the comprehensive optimization design of water efficiency and dynamic characteristics of the runner was developed. The above research constitutes a complete set of procedures and methods for the analysis of the dynamic characteristics of the runner. At the same time, each part can operate independently, which can be used to calculate the liquid-solid coupling vibration of the runner, the dynamic characteristics of the transition process and the comprehensive optimization design of the runner. The research results have been applied in forster technology co., ltd., and have been well received.
1.Francis turbine has the advantages of compact structure, high efficiency and can adapt to a wide range of water head of turbine type.
2.When the water flow through the turbine wheel, it enters to radial, axial flow, so it is also called the radial axial flow turbine;
3.Francis turbine is also called the Francis turbine. The water flow from the surrounding radial inflow runner, then approximate axial flow runner, runner by the crown, under the ring and the blade;
4.It is applicable to the head from a range of 20 meters of up to 700 meters, has the advantages of simple structure, stable operation, and high efficiency, but it is generally used in the head in the range(50 to 400 meters). Single output from tens of KW to several 101000 tile. At present this kind of turbine maximum output has exceeded 700000 kilowatts. A turbine is one of the most extensively used.
5.Francis hydro turbine generator unit is one of our common hydraulic turbines. It consists of hydraulic turbines, generators and other basic components.
