Hydropower is one of the renewable energy sources having the highest conversion
efficiency than other renewable energy sources. The hydro turbine is considered as the …

The hydropower station with a super long headrace tunnel is a significant development type
for hydropower energy. By constructing a super long headrace tunnel, the huge natural …

The current development trend of China's hydropower is moving toward ultra-high heads,
complex geological scenarios, ultra-large capacities, and the Tibetan region. The …

A robust fuzzy control method for fractional order hydro-turbine governing system (FOHGS)
in the presence of random disturbances is investigated in this paper. Firstly, the …

For a large hydropower plant (HPP) with long-distance tunnels, a surge tank needs to be
installed to ensure the safety of the HPP during hydraulic transients (ie, load changes in …

This study focuses on the critical issue: whether uncertainties in parameters make a
difference to transient characteristics. To solve this problem, a mathematical model is …

In a pressurized water conveyance system, such as a hydropower system, during hydraulic
transients, maximum and minimum pressures at various controlling sections are of prime …

Controlling pressure impact of water hammer is an important guarantee for safe and stable
running of pipeline systems. Previously, we proposed a spring self-adaptive auxiliary control …

Forces and moments increase rapidly in complex interactions while maintaining stability of
the shaft for the hydroelectric generating system in the load rejection process. These …

Successive load rejection is one of the most crucial transient processes for calculating the
maximum pressure in spiral case and maximum rotating speed of runner. One-dimensional …
