摘要

小型水力发电厂(SHPP)是一种可能的可再生能源。它可以放置在小溪流上，没有任何高层建筑，这使得SHPP对环境友好。然而，一个SHPP有一个感应发电机，其运行效率在标称功率，但不是在较低的功率。本文研究了一种在低功率下通过降低定子电压来提高效率的方法。前面已经介绍了这种方法，现在的重点是描述降低定子电压的可能技术。对于每一种技术，将计算一年内节省的能源，并将与所用技术系统的成本进行比较，证明节省的资金。

Techniques to Increase the Efficiency of Small Hydro Power Plants with Induction Machine

A small hydro power plant (SHPP) is one possible type of renewable energy sources. It could be placed on small streams without any tall buildings, which makes the SHPP friendly to the environment. However, a SHPP has an induction generator which operates efficiency in nominal power but not in lower power. This paper deals with a method to increase the efficiency in low power with reducing the stator voltage. This method was described earlier and now the key point is to describe possible techniques to decrease the stator voltage. For each of these techniques energy savings in a year period will be calculated and financial savings will be demonstrated in comparison to the cost of the used technical system.
