Description

Small Hydro Power Supply System {SMALL HYDROELECTRIC POWER SUPPLY SYSTEM}

The present invention relates to a small power generation power supply system, and more particularly, to the small power generation power supply system that can ensure the stability of the power system and at the same time efficient power management by storing the generated electrical energy and discharge when necessary It is about.

In general, small hydro power means small-scale hydropower with less than 15,000 kW of capacity, but domestically, less than 10,000 kW (2003.1, Ministry of Commerce, Industry and Energy No. 192) is called hydropower. Small-scale hydropower generation is not different from general large-scale hydropower generation in principle, but considering that the large-scale hydropower generation has a negative effect on the environment, it can be said to be a small and technically simple hydroelectric power generation in harmony with local conditions.

Small hydro power generation is a clean energy without pollution and has a confirmed amount of 15MW in Korea, and has high energy density compared to other renewable energy sources. And development support projects are competitively active.

In addition, small hydro power generation has less CO2 emissions than other energy sources and is regarded as an eco-friendly low carbon green technology.It has the highest energy production per unit capacity among domestic renewable energy, and has a long history of applied element technology. It is a proven utility energy with low overseas dependency.

In the hydrophobic power generator as described above, the hydrophobic power generator is installed at a lower position than the storage facility, and the hydrophobic power generator is operated by the drop of water falling along the pipe line to produce electrical energy to supply electrical energy to the power system. As the load increases, the rotation of the aberration decreases, causing the power frequency to shake.

In this way, when the power frequency fluctuates as the load of the demand source increases, the amount of water discharged is increased by increasing the amount of water discharged through the governor control, thereby correcting the power frequency to supply stable electric energy.

However, in the case of the method of correcting the power frequency through the mechanical control to adjust the amount of water discharged through the governor control as described above, the mechanical aging of the mechanical device such as the governor is repeatedly generated, thereby increasing the physical fatigue, thereby causing mechanical aging. As it progresses very quickly, the service life of the hydro power plant is not only shortened drastically, and there is a problem in that it is not possible to respond quickly in an emergency due to the impossibility of quick response according to the load demand of the electric energy demand destination.
