Universal power and cavitation stand for testing hydraulic turbines and reversible pump-turbine motor-generator units

Abstract

The power and cavitation stand of KhTZ is a universal device for testing model hydraulic turbines and reversible pump-turbine units of various types. The design of the stand, its power equipment, and measuring devices permit conducting comprehensive tests of models in a wide range of heads, right up to those close to the prototype. The introduction, on the stand, of a system for automatic control and stabilization of the test regimes and method of measuring regime parameters by means of the measuring and computing complex made it possible to reduce by about half the measurement errors and to raise the accuracy of the tests to the level attained at the best Soviet and foreign laboratories. On the whole, the values and stability of the test regime parameters, dimensions and layout of the models, and the measurement and test methods used on the stand correspond to the IEC recommendations and standards.
