Original Abstract

In the Czech Republic the environmental flow in streams is frequently exploited for power generation at small hydropower plants located at dams. The performance of hydropower plants is significantly influenced by the durability and service life of installed technical equipment, which in the case of small hydropower plants is often simple and inexpensive. The study presents the results of durability analysis based on the analysis of defects and failures of two turbines (Francis, crossflow Banki) installed on the bypass of the bottom outlets of the Sance Dam in the Czech Republic. Firstly, the durability of the equipment and the main types of turbine shutdowns are defined. Empirical probability distribution curves for time to failure are plotted for both turbine sets based on available records of incidents and reasons for individual shutdowns from 20 years of operation. The analysis shows the average periods between shutdowns and period length probabilities between shutdowns for each turbine set.
