摘要
抽水蓄能电站在电力系统中承担着削峰填谷、调频、调相、事故备用等作用,对保障电网平稳运行意义重大。随着泛在电力物联网的战略推进,电网提高了对电力系统各环节的性能要求。抽水蓄能机组通过改变转速,可显著提高其发电能力和调节性能,可更充分地发挥抽水蓄能电站的作用,电网对抽水蓄能变速机组的需求愈发强烈。
pumped storage power station plays the role of peak shaving and valley filling,frequency modulation,phase modulation and accident standby in power system,which is of great significance to ensure the smooth operation of power grid.With the promotion of the ubiquitous power Internet of things strategy,the power grid has improved the performance requirements of all links of the power system.By changing the speed of pumped storage unit,its power generation capacity and regulation performance can be significantly improved,and the role of pumped storage power station can be brought into full play.The demand of power grid for Pumped Storage variable-speed unit is becoming stronger and stronger.
