抽水蓄能发电系统中的新技术

抽水蓄能电站具有填谷调峰和事故备用等多种用途。它能够极大地改善电力系统的运行条件，因此，一定比例的抽水蓄能电站在电力系统中是必需的。但是在抽水工况下，利用水泵水轮机的特性进行功率输入调整比较困难，从而使得抽水工况下的电力供需调整具有一定限度。采用可调速抽水蓄能发电系统即可使这种情况得到有效地改善，简单介绍了可调速抽水蓄能发电系统的工作原理。

New Technology of Pumped-Storage Power Generation System

Pumped-storage power plants can undertake the tasks of filling valley and modulating peak. It can greatly improve the power system operating conditions, lower system power costs; therefore, a certain percentage of the pumped storage power station in the power system is essential. However, in the pumping conditions, the use of the characteristics of the pump-turbine power input adjustment is more difficult, so that the adjustment of power supply and demand may have certain limits. The new technology not only has the advantage of pumped-storage generation system but also has the ability of control the generation power with high speed, so that the new technology will be spread widely.
