COMPARATIVE ANALYSIS OF POWER TESTING METHODS OF HYDROELECTRIC POWER PLANT UNITS

The paper considers a comparative analysis of existing methods of energy testing of HPP units, such as relative and absolute method. Energy tests are carried out in order to obtain operational and capacity characteristics of the turbine and units of the hydropower plant, which further allows the personnel of the hydropower plant to operate the turbine in optimal modes. Technical indicators recorded in the process of power testing are analyzed. Positive and negative sides of the methods are considered, appropriate recommendations for their use are given.
