求翻译：水力发电系利用河川、湖泊等位于高处具有位能的水流，当它流至低处时，它可以将其中所含之位能转换成水轮机之动能。是什么意思？

The hydroelectric Department in height has potential energy of rivers, lakes and other water, when it flows to the lower, it can be contained in the potential energy convert the kinetic energy of the turbine.

Hydroelectric power systems use rivers, and lakes, is located on a high, somebody who can help with the flow, and when it flows to the lower, it can be to one who knows one of the converted into kinetic energy of water turbines.

The water power sends the electrical system using the river, the lake equipotential line has the potential energy current of water in the high place, when it flows to the low spot, it may contain the potential energy to transform kinetic energy of the hydraulic turbine.

Hydropower use in high places such as rivers and lakes has a potential energy of the water, when you stream it to the lower, it can be the potential energy of a converted to the kinetic energy of a turbine.
