摘要
可逆式机组水泵工况运行需解决大型同步电动机的启动问题。文章介绍一种电流源交 -直 -交变频器型全数字大功率交流变频调速装置在广州抽水蓄能电站 2期机组的应用 ,说明其工作原理、功能、配置及特点。由于应用此种变频调整装置 ,提高了设备的控制性能和运行可靠性 ,保证机组抽水工况的快速启动。
To solve the problem for large synchronous motor's start up to pump mode for reversible unit,the thesis introduces one kind of full digital giant power AC frepuency converter besed on the current source DC link converter and describes its configuration,function,operation principles.The adoption of this converter simplifies the coures of design,installation and commissioning and improves the control performance and operating realibility and ensures the quality of product and the quick start up.
