Abstract

The invention relates to a unit support platform used for model tests of pumped storage dynamic characteristics, comprising a frame, an umbrella support, a universal coupling, a detachable flywheel installed on the shaft of a water pump turbine, a model connecting plate, a fixed Standoffs, draft tube supports and grid bases. The invention can not only ensure the operation stability of the detachable flywheel at high mechanical speed, but also improve the angular compensation ability of the shaft system, reliably transmit torque and motion, and realize high efficiency and stability of the pump turbine shaft and the doubly-fed motor shaft transmission. The invention has a compact structure, takes up little space, has the characteristics of reinforcement, buffering and vibration reduction, and can effectively reduce the operation risk of the seawater pumped storage dynamic characteristic model test. The invention has the characteristics of buffering, damping and improving the dynamic performance of the shaft system, and is suitable for the dynamic characteristic model test device of the pumped energy storage unit with high mechanical speed and large moment of inertia and the dynamic characteristic of the conventional hydropower generating unit.

Description

technical field [0001] The invention relates to a support platform, in particular to a unit support platform used for model test of dynamic characteristics of pumped storage. Background technique [0002] With the transformation of the world energy system from fossil energy to renewable energy, my country and the rest of the world are exploring the theory and practice of promoting the consumption of renewable energy. As the world's largest renewable energy source, the driving force of hydropower development has changed from meeting the demand for power generation to regulating the dynamic quality of the system. The pumped storage power station plays an important role in compensating for the intermittency of renewable energy and undertaking the task of frequency regulation and peak regulation of the power grid. It can be called the "quick response force" of the power system. The seawater pumped storage power station is an important innovation of the traditional pumped storag...
