Problems solved by technology

On the one hand, the transition process theory and numerical calculations have fully considered the interaction of hydro-mechanical-electrical joint transition processes; on the other hand, the existing methods and results of separate studies of water, mechanical and electrical cannot meet the complex layout requirements of various water delivery systems. The needs of the design and operation of power stations (especially: large-scale long-distance underground hydropower stations, pumped storage power stations), so it is necessary to carry out the overall physical simulation of the transition process of hydropower stations including hydraulic systems, mechanical systems and electrical systems

Abstract

An overall physical model test platform for the transient process of a hydropower station comprises a circulating water system (1), an excitation simultaneous protection system (2), a speed regulation control system (3), a frequency conversion commutation system (4), a monitoring system (5), a load system (6), a measuring system (7), a model unit system (8) and a model water channel system (9). The transient process of major fluctuations, minor fluctuations and hydraulic disturbance and experimental researches on other related issues can be conducted on the platform. The overall physical model test platform has the advantages that the integration level is high, working performance is stable and reliable, operation is simple, control is precise, and various fundamentality and application fundamentality tests related to the transient process of the hydropower station can be effectively completed. The overall physical model test platform is suitable for large-sized, medium-sized and small-sized conventional model hydropower stations and model pumped-storage hydroelectricity stations.

Description

technical field [0001] The invention relates to a hydropower station model test platform, in particular to a hydropower station transition process overall physical model test platform. Background technique [0002] Model test and numerical calculation are two complementary research methods that are indispensable for scientific research and engineering application. Among them, model tests can not only verify the reliability and accuracy of theoretical analysis and numerical calculation results, but also observe and reveal the internal laws of physical phenomena, and promote the development of theoretical analysis and numerical calculation. [0003] The transition process of hydropower diversion power generation system is a complex dynamic process in which fluid, machinery, electricity, and even structure are coupled with each other. On the one hand, the transition process theory and numerical calculations have fully considered the interaction of hydro-mechanical-electrical j...
