Апстракт:
In order to reduce the price of energy obtained from renewable sources, small and micro hydro power plants have lately been increasingly using pumps that which operate in the reverse mode, i.e. pumps as turbines (PAT). Pumps in the reverse mode have lower degrees of efficiency than conventional turbines, but their price of procurement and exploitation is also lower. The efficiency of PAT can be increased through constructive corrections of pumps. When selecting a PAT, it is essential to predict the performance the pump when it operates in the reverse mode based on its characteristics. There are various methods for predicting the performance of a pump that operates as a turbine. The paper presents the available methods for predicting the performance a centrifugal pumps when operating in the turbine mode. The authors analyze the applicability and reliability of particular methods, depending on the width of the work area in relation to the optimal operating point.
