在保加利亚,为 Chaira 泵站制造了4台可逆式水泵——水轮机,是世界上水头最高的单级蓄能装置。本文在简单介绍发电站后,又讨论了机组的设计特性、结构强度和运行控制。Chaira 在东欧是最大的蓄能泵站之一,用4台机组可发电81.6万千瓦。Chaira 安装了单级可逆式水泵——水轮机,在发电状态下每台的转速为600转/分,水 In Bulgaria, four reversing pumps - turbines have been built for the Chaira pumping station - the highest single-stage accumulator in the world. After a brief introduction of power station, this paper discusses the design features, structural strength and operation control of the unit. Chaira is one of the largest storage pump stations in Eastern Europe, generating 816,000 kilowatts with 4 units. Chaira installed a single-stage reversible pump - turbine, each in the state of power generation speed of 600 rev / min, water
