Small hydroelectric power plants (SHPP) are accepted by the legislation of EU Member States to benefit from renewable energy promotion scheme through various market mechanism. The SHPPs are a particular form and case of hydroelectric power plants (HPP) and are having a maximum capacity of 10 MW. Since the green certificate (GC) promotion scheme was awarded in Romania (2008), a considerable number of SHPP were constructed and commissioned in the last years. These projects have the same philosophy as a large hydro, ...

Fatigue damage is determined from time signals of loading, usually in the form of stress or strain. However, there are many design scenarios when the loading, or fatigue damage process, cannot easily be defined using time signals. In these cases the design/operation engineer usually has to use a test based approach to evaluate the fatigue life of the structure or the component. Alternatively, a frequency based fatigue calculation can be used where the loading and response are represented using Power Spectral Densi...

Renewable energy is a key factor in the sustainable development of any modern society. The development of renewable energy project must continue to be part of a competitive economy and the research and innovation of this domain should be a priority. One of the renewable energy sources (RES) that are reliable, provides predictable energy, assures the energy supply in remote areas and at the end of the power transmission lines, are small hydro power plants (SHPP). In Romania SHPP are not new, being part of the devel...

The energy sector is an essential component in any nationпїЅs economy and well-being. The security and safety of any energy grid system is nowadays a strongpoint in mid and long term strategies when it comes to national development. Safety and security of energy supply is a multicomponent factor that includes: power generation systems, power transport and distribution systems and consumer management. The power generation units in Romania are very complex and they include different sources like coal, gas, nuclear, ...

Renewable energy is playing an important role in the development of any modern country. Numerous renewable energy sources are now harvested on a large scale with the main purpose to reduce the greenhouse gas emissions and diminish the use of fossil fuels. European Union member states agreed to achieve important quotas of renewable energy in their consumption until 2020 in energy and in transportation. Romania has the legislation aligned with the EU directives, therefore the government has issued specific legislati...
