变速抽水蓄能机组水力-电气耦合仿真技术研究
Research on hydraulic-electrical and electromechanical coupling simulation technology of variable-speed pumped storage units
摘要
Abstract
In order to effectively improve the safe and stable operation level of the power grid as well as the utilization rate of new energy resources,a refined model of a variable-speed pumped storage unit,including a pressurized water intake system,pump-turbine,alternating current(AC)excitation gene-rator,and governor,was established.In-depth calculation and analysis were conducted on typical hy-draulic transient processes of pumped storage power stations.The research results show that the numeri-cal simulation model of the AC excitation variable-speed unit can effectively simulate each working con-dition,and the simulation dynamic process is consistent with the actual operation process of the unit,with good results.When the variable-speed pumped storage unit increases or decreases the load under the governor power model of the power generation condition,the unit speed is controlled by AC excita-tion,and its speed can be quickly and accurately adjusted,and the active power on the stator side can also be quickly stabilized at the specified value.When the unit increases or decreases load under the governor opening model of the power generation condition,the unit output is controlled by AC excita-tion.The active power on the stator side can be quickly stabilized at the specified value,while the rota-tional speed of the unit is slowly stabilized at the specified value.关键词
